报告简介：
The lecture will discuss dynamic security concerns on island systems with high penetration of RES focusing on frequency. In particular, the security rules that can be embedded in unit commitment to provide secure, optimal schedules will be derived using analytical calculations and data driven approaches. The application of classic Decision Trees for on-line dynamic security assessment of the island of Crete will be analyzed. Furthermore, the application of Optimal Classification Trees for the island of Rhodes will be presented and the results of the various methods compared. Finally, the improvement of the results achieved by classifier retraining will be discussed.

TSO/DSO Collaboration- Local Flexibility Markets
报告时间：2023年11月04日 上午9：30-10：30

报告简介：
The adoption of DG and RES within the distribution network is on the rise, leading to a gradual displacement of conventional power stations. This shift necessitates the availability of ancillary services and flexibility from DG and RES sources. To address this evolving energy landscape, one strategic approach involves the establishment of market mechanisms that bring TSOs and DSOs into an expanded market structure. These mechanisms can take two forms: centralization within the existing balancing market or decentralization through the introduction of local markets. In this presentation, an analysis of these market models and the variations of them will be provided. The various products (balancing, voltage/frequency, congestion, etc.) offered within these markets will be analyzed and key findings gathered from multiple European research projects will be presented.

报告简介：
New CHIL and PHIL experimental setups, applications and considerations implemented in the Electric Energy Systems Laboratory (EESL) of ICCS-NTUA will be presented and discussed. The presentation will commence by showcasing the interaction between a hardware inverter controller and a hardware protection relay implementing an islanding detection scheme, in a CHIL setup. Next, the design and testing of an adaptive protection scheme, adjusting setting groups of three feeder relays using industrial communication protocols (IEC 61850, DNP3) in a CHIL setup, will be presented. Moreover, the CHIL testing of an industrial controller for Grid Code Requirements compliance, facilitating the integration of renewable energy sources and advanced technologies into the grid, will be highlighted. In the realm of microgrids, the HIL testing of a developed in-house energy management system will demonstrate cutting-edge performance in simulating and refining real-world microgrid operation using a digital twin, optimizing renewable energy utilization. Emphasis will be placed on the combined CHIL and PHIL setup, investigating the interaction between a controller for seamless microgrid transition and a hardware PV inverter. A critical factor for the successful PHIL implementation is to have a stable but at the same time accurate setup, thus our recent work in the frame of ERIGrid 2.0 project, published at IEEE Transactions on Industrial Electronics on extended range of high-fidelity setups for PHIL testing will be presented. Lastly, the presentation will highlight the benefits of Geographically Distributed Real-Time Simulations and the work carried out within ERIGrid 2.0, enabling comprehensive power system analysis and optimization over larger areas.
