Existing research has predominantly restricted ECS cable layouts to conventional radial or ring structures and employed graph theory heuristics for solutions. However, both economic efficiency and reliability of the OWFs heavily depend on their ECS structure, and the optimal ECS cable layout often deviates from typical configurations. In this context, this paper introduces a novel reliability-based ECS cable layout planning method for large-scale OWFs, employing a two-stage stochastic programming approach to address uncertainties of wind power and contingencies. To enhance reliability, the model incorporates optimal post-fault network reconfiguration strategies by adjusting wind turbine power supply paths through link cables. To tackle computation challenges arising from numerous contingency scenarios, a customized progressive contingency incorporation (CPCI) framework is developed to solve the model with higher efficiency by iteratively identifying non-trivial scenarios and solving the simplified problems. The convergence and optimality are theoretically proven. Numerical tests on several real-world OWFs validate the necessity of fully optimizing ECS structures and demonstrate the efficiency of the CPCI algorithm. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2409.12873v1-abstract-full').style.display = 'none'; document.getElementById('2409.12873v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 September, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2409.08191">arXiv:2409.08191</a> <span> [<a href="https://arxiv.org/pdf/2409.08191">pdf</a>, <a href="https://arxiv.org/ps/2409.08191">ps</a>, <a href="https://arxiv.org/format/2409.08191">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> </div> <p class="title is-5 mathjax"> Optimal Operation of Distribution System Operator and the Impact of Peer-to-Peer Transactions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Lin%2C+H">Hanyang Lin</a>, <a href="/search/eess?searchtype=author&query=Guo%2C+Y">Ye Guo</a>, <a href="/search/eess?searchtype=author&query=Nazir%2C+F+U">Firdous Ul Nazir</a>, <a href="/search/eess?searchtype=author&query=Zhou%2C+J">Jianguo Zhou</a>, <a href="/search/eess?searchtype=author&query=Chung%2C+C+Y">Chi Yung Chung</a>, <a href="/search/eess?searchtype=author&query=Hatziargyriou%2C+N">Nikos Hatziargyriou</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2409.08191v1-abstract-short" style="display: inline;"> Peer-to-peer (P2P) energy trading, commonly recognized as a decentralized approach, has emerged as a popular way to better utilize distributed energy resources (DERs).

In order to better manage this user-side decentralized approach from a system operator's point of view, this paper proposes an optimal operation approach for distribution system operators (DSO), comprising internal prosumers who engage in P2P transactions. The DSO is assumed to be a financial neutral entity, holding the responsibility of aggregating the surplus energy and deficit demand of prosumers after their P2P transactions while dispatching DERs and considering network integrity. Impacts of P2P transactions on DSO's optimal operation have been studied. Results indicate that energy matching P2P trading where only the total amount of energy over a given period of time is defined may affect quantities of energy exchanged between the DSO and the wholesale market, but not internal dispatch decisions of the DSO. Different levels of real-time power consistency may lead to different total surpluses in the distribution network. For the real-time power matching P2P trading, as a special case of energy matching P2P trading, the provided energy and total surplus are not affected. In other words, DSO can safely ignore P2P transactions if they follow the format defined in this paper. Case studies verify these conclusions and further demonstrate that P2P trading will not affect physical power flow of the whole system, but the financial distribution between the DSO and prosumers. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2409.08191v1-abstract-full').style.display = 'none'; document.getElementById('2409.08191v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 September, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.20733">arXiv:2405.20733</a> <span> [<a href="https://arxiv.org/pdf/2405.20733">pdf</a>, <a href="https://arxiv.org/format/2405.20733">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> </div> <p class="title is-5 mathjax"> Dynamic Microgrid Formation Considering Time-dependent Contingency: A Distributionally Robust Approach </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Liu%2C+Z">Ziang Liu</a>, <a href="/search/eess?searchtype=author&query=Cai%2C+S">Sheng Cai</a>, <a href="/search/eess?searchtype=author&query=Wu%2C+Q">Qiuwei Wu</a>, <a href="/search/eess?searchtype=author&query=Shen%2C+X">Xinwei Shen</a>, <a href="/search/eess?searchtype=author&query=Zhang%2C+X">Xuan Zhang</a>, <a href="/search/eess?searchtype=author&query=Hatziargyriou%2C+N">Nikos Hatziargyriou</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2405.20733v1-abstract-short" style="display: inline;"> The increasing frequency of extreme weather events has posed significant risks to the operation of power grids.

During long-duration extreme weather events, microgrid formation (MF) is an essential solution to enhance the resilience of the distribution systems by proactively partitioning the distribution system into several microgrids to mitigate the impact of contingencies. This paper proposes a distributionally robust dynamic microgrid formation (DR-DMF) approach to fully consider the temporal characteristics of line failure probability during long-duration extreme weather events like typhoons. The boundaries of each microgrid are dynamically adjusted to enhance the resilience of the system. Furthermore, the expected load shedding is minimized by a distributionally robust optimization model considering the uncertainty of line failure probability regarding the worst-case distribution of contingencies. The effectiveness of the proposed model is verified by numerical simulations on a modified IEEE 37-node system. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.20733v1-abstract-full').style.display = 'none'; document.getElementById('2405.20733v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 31 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">5 pages, 5 figures, Accepted by PES General Meeting 2024</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2404.16974">arXiv:2404.16974</a> <span> [<a href="https://arxiv.org/pdf/2404.16974">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> </div> <p class="title is-5 mathjax"> DRL2FC: An Attack-Resilient Controller for Automatic Generation Control Based on Deep Reinforcement Learning </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Dimitropoulos%2C+V">Vasileios Dimitropoulos</a>, <a href="/search/eess?searchtype=author&query=Syrmakesis%2C+A+D">Andreas D.

However, the increasing digitization and interconnection of power grid infrastructure expose AGC systems to new vulnerabilities, particularly from cyberattacks such as false data injection attacks (FDIAs). These attacks aim at manipulating sensor measurements and control signals by injecting tampered data into the communication mediums. As such, it is necessary to develop innovative approaches that enhance the resilience of AGC systems. This paper addresses this challenge by exploring the potential of deep reinforcement learning (DRL) to enhancing the resilience of AGC systems against FDIAs. To this end, a DRL-based controller is proposed that dynamically adjusts generator setpoints in response to both load fluctuations and potential cyber threats. The controller learns these optimal control policies by interacting with a simulated power system environment that incorporates the AGC dynamics under cyberattacks. The extensive experiments on test power systems subjected to various FDIAs demonstrate the effectiveness of the presented approach in mitigating the impact of cyberattacks. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.16974v1-abstract-full').style.display = 'none'; document.getElementById('2404.16974v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 25 April, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">2 pages, 2 figures, submitted to the 14th Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2306.07082">arXiv:2306.07082</a> <span> [<a href="https://arxiv.org/pdf/2306.07082">pdf</a>, <a href="https://arxiv.org/format/2306.07082">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Cryptography and Security">cs.CR</span> </div> </div> <p class="title is-5 mathjax"> Residual-Based Detection of Attacks in Cyber-Physical Inverter-Based Microgrids </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Intriago%2C+A">Andres Intriago</a>, <a href="/search/eess?searchtype=author&query=Liberati%2C+F">Francesco Liberati</a>, <a href="/search/eess?searchtype=author&query=Hatziargyriou%2C+N+D">Nikos D.

The work identifies a research gap in modeling and analyzing stealthy intermittent integrity attacks in MGs, which are designed to maximize damage and cancel secondary control objectives. To address this, the paper proposes a nonlinear residual-based observer approach to detect and mitigate such attacks. In order to ensure a stable operation of the MG, the formulation then incorporates stability constraints along with the detection observer. The proposed design is validated through case studies on a MG benchmark with four distributed generators, demonstrating its effectiveness in detecting attacks while satisfying network and stability constraints. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2306.07082v1-abstract-full').style.display = 'none'; document.getElementById('2306.07082v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 June, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Accepted at IEEE Transactions on Power Systems</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2304.03615">arXiv:2304.03615</a> <span> [<a href="https://arxiv.org/pdf/2304.03615">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> </div> <p class="title is-5 mathjax"> An investigation of factors affecting Fast-Interaction Converter-driven Stability in Microgrids </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Saridaki%2C+G">Georgia Saridaki</a>, <a href="/search/eess?searchtype=author&query=Paspatis%2C+A+G">Alexandros G.

Interactions between the fast control loops or between the fast control loops and passive elements of the grid, have been reported in literature and have led to introducing a new type of stability: the Fast-Interaction Converter-driven Stability (FICDS). In this paper, factors affecting the FICDS, such as tuning controller parameters, line parameters, number of interconnected inverters, are explored in four microgrid topologies, operating in grid connected and islanded mode. With the use of an impedance based model which tracks the poles of the CDS transfer functions of each system, their stability has been assessed. The obtained results have been verified via time-domain simulations. Simulations from the islanded microgrid of Gaidouromantra in Greece showcase the impact of the control parameters on the operation of the system and indicate the need for further investigation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2304.03615v1-abstract-full').style.display = 'none'; document.getElementById('2304.03615v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 7 April, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Accepted for presentation to the International Conference on Power Systems Transients (IPST2023) which will be held Thessaloniki, Greece, June 12-15, 2023</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2205.11171">arXiv:2205.11171</a> <span> [<a href="https://arxiv.org/pdf/2205.11171">pdf</a>, <a href="https://arxiv.org/format/2205.11171">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Cryptography and Security">cs.CR</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1109/JSYST.2023.3305757">10.1109/JSYST.2023.3305757 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Distributed Energy Resources Cybersecurity Outlook: Vulnerabilities, Attacks, Impacts, and Mitigations </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Zografopoulos%2C+I">Ioannis Zografopoulos</a>, <a href="/search/eess?searchtype=author&query=Hatziargyriou%2C+N+D">Nikos D.

Towards this goal, distributed energy resources (DER), including rooftop solar panels, battery storage, electric vehicles, etc., are becoming ubiquitous in power systems. Power utilities benefit from DERs as they minimize operational costs; at the same time, DERs grant users and aggregators control over the power they produce and consume. DERs are interconnected, interoperable, and support remotely controllable features, thus, their cybersecurity is of cardinal importance. DER communication dependencies and the diversity of DER architectures widen the threat surface and aggravate the cybersecurity posture of power systems. In this work, we focus on security oversights that reside in the cyber and physical layers of DERs and can jeopardize grid operations. Existing works have underlined the impact of cyberattacks targeting DER assets, however, they either focus on specific system components (e.g., communication protocols), do not consider the mission-critical objectives of DERs, or neglect the adversarial perspective (e.g., adversary/attack models) altogether. To address these omissions, we comprehensively analyze adversarial capabilities and objectives when manipulating DER assets, and then present how protocol and device-level vulnerabilities can materialize into cyberattacks impacting power system operations. Finally, we provide mitigation strategies to thwart adversaries and directions for future DER cybersecurity research. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2205.11171v4-abstract-full').style.display = 'none'; document.getElementById('2205.11171v4-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 23 May, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">IEEE Systems Journal (2023)</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2105.06092">arXiv:2105.06092</a> <span> [<a href="https://arxiv.org/pdf/2105.06092">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1109/TSG.2016.2624633">10.1109/TSG.2016.2624633 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Voltage Regulation Support Along a Distribution Line by a Virtual Power Plant Based on a Center of Mass Load Modeling </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Moutis%2C+P">Panayiotis Moutis</a>, <a href="/search/eess?searchtype=author&query=Georgilakis%2C+P+S">Pavlos S.

Classic stability methods are not well-suited for these dynamic systems as they involve centralized gathering of information and computation of the system's eigenvalues, processes which are oftentimes not privacy-preserving and computationally burdensome. System operators (SOs) would nowadays have to be able to quickly and efficiently assess small-signal stability as the power grid operating conditions change more dynamically while also respect the privacy of the distributed energy resources (DERs). Motivated by all these, in this paper we introduce a framework that comprises a computationally efficient, privacy-preserving, distributed and compositional stability assessment method. Our proposed method first calls for representative agents at various buses to exchange information with their neighbors and design their local controls in order to meet some local stability conditions. Following that, the agents are required to notify the SO whether their local conditions are satisfied or not. In case the agents cannot verify their local conditions they can augment their local controls using a global control input. The SO can then warrant stability of the interconnected power grid by assembling the local stability guarantees, established by the agents, in a compositional manner. We analytically derive the local stability conditions and prove that when they are collectively satisfied stability of the interconnected system ensues. We illustrate the effectiveness of our proposed DSA method via a numerical example centered around a three-bus power grid. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2003.07475v1-abstract-full').style.display = 'none'; document.getElementById('2003.07475v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 16 March, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">8 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1710.04131">arXiv:1710.04131</a> <span> [<a href="https://arxiv.org/pdf/1710.04131">pdf</a>, <a href="https://arxiv.org/format/1710.04131">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Computers and Society">cs.CY</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/978-3-319-64635-0_15">10.1007/978-3-319-64635-0_15 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Validating Intelligent Power and Energy Systems - A Discussion of Educational Needs </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Kotsampopoulos%2C+P">Panos Kotsampopoulos</a>, <a href="/search/eess?searchtype=author&query=Hatziargyriou%2C+N">Nikos Hatziargyriou</a>, <a href="/search/eess?searchtype=author&query=Strasser%2C+T+I">Thomas I.

Additionally, automation and information technology plays an important role in order to operate and optimize such cyber-physical energy systems with a high(er) penetration of fluctuating renewable generation and controllable loads. As a result of these developments the validation on the system level becomes much more important during the whole engineering and deployment process, today. In earlier development stages and for larger system configurations laboratory-based testing is not always an option. Due to recent developments, simulation-based approaches are now an appropriate tool to support the development, implementation, and roll-out of smart grid solutions. This paper discusses the current state of simulation-based approaches and outlines the necessary future research and development directions in the domain of power and energy systems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1710.02315v1-abstract-full').style.display = 'none'; document.getElementById('1710.02315v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 October, 2017; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2017. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">8th International Conference on Industrial Applications of Holonic and Multi-Agent Systems (HoloMAS 2017)</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1710.02312">arXiv:1710.02312</a> <span> [<a href="https://arxiv.org/pdf/1710.02312">pdf</a>, <a href="https://arxiv.org/format/1710.02312">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Systems and Control">eess.SY</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/978-3-319-64635-0_12">10.1007/978-3-319-64635-0_12 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> An Integrated Research Infrastructure for Validating Cyber-Physical Energy Systems </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/eess?searchtype=author&query=Strasser%2C+T+I">Thomas I.

The intermittent nature and limited storage capabilities of renewables culminate in new challenges that power system operators have to deal with in order to regulate power quality and ensure security of supply. At the same time, the increased availability of advanced automation and communication technologies provides new opportunities for the derivation of intelligent solutions to tackle the challenges. Previous work has shown various new methods of operating highly interconnected power grids, and their corresponding components, in a more effective way. As a consequence of these developments, the traditional power system is being transformed into a cyber-physical energy system, a smart grid. Previous and ongoing research have tended to mainly focus on how specific aspects of smart grids can be validated, but until there exists no integrated approach for the analysis and evaluation of complex cyber-physical systems configurations. This paper introduces integrated research infrastructure that provides methods and tools for validating smart grid systems in a holistic, cyber-physical manner. The corresponding concepts are currently being developed further in the European project ERIGrid. <a class="is-size-7" style="white-space: nowrap;"
