Advancements in Power System Control and Protection

The field of power systems is witnessing significant developments in control and protection technologies, driven by the increasing integration of renewable energy sources and inverter-based resources. Researchers are exploring innovative solutions to enhance the reliability, efficiency, and resilience of power systems. Notably, advances in energy control strategies, data-driven analysis, and fault location methods are improving the overall performance of power systems. Some of the key areas of focus include the development of advanced control strategies for wind farms and HVDC systems, data-driven approaches for post-event analysis and fault location, and the impact of inverter-based resources on protection systems. Particularly noteworthy papers include: The paper on the Energy Control Strategy to Enhance AC Fault Ride-Through in Offshore Wind MMC-HVDC Systems, which presents a novel energy control scheme that combines storage and dissipation of surplus power to ensure safe operation of offshore wind farms. The paper on Data-Driven Post-Event Analysis with Real-World Oscillation Data from Denmark, which demonstrates the effectiveness of Extended Dynamic Mode Decomposition in identifying the main contributors to oscillations in power grids. The paper on Analytical Phasor-Based Fault Location Enhancement for Wind Farm Collector Networks, which proposes a general compensation framework to improve fault location accuracy in wind farm collector networks. The paper on Understanding Regional Inertia Dynamics in CAISO from Real Grid Disturbances, which presents a measurement-based framework for estimating grid inertia and highlights the importance of regional inertia monitoring for ensuring grid reliability.
