Several large blackouts or interruption events in relation to the improper operation of IBRs under voltage distur bances have been reported in recent years. Although a consensus has been r eached that IBRs should be able to ride through various voltage disturbanc es while providing dynamic voltage support (DVS) to the grid\, it is still not clear how to achieve the optimal DVS. This talk will share our recent research efforts in improving the DVS performance of IBRs under abnormal voltage conditions. Three critical questions are answered via optimisation . 1) What is the maximum DVS capability of a single IBR? 2) How to impleme nt the maximum DVS without relying on the knowledge of grid model paramete rs? 3) How do multiple IBRs interact with each other in a network? The opt imisation-based methodologies open up an effective way to explore sophisti cated control strategies of IBRs under large disturbances\, and the resear ch findings complement and even challenge our physical intuition.\n\nSpeak er:\n\nBikash Pal is a Professor of Power Systems at Imperial College Lond on (ICL).

SIEMENS R&D collaborated with him to develop fast power flow and volt-var control tools in Spectrum Power\, an advanced module for distribu tion management system solution from SIEMENS. This is now commissioned in distribution control centres in Columbia\, Bosnia Norway and Azerbaijan se rving 15 million customers in these countries. GE commissioned sequel of p rojects with him to analyse and solve wind farm HVDC grid interaction prob lems (2013-2019). Prof Pal was the chief technical consultant for a panel of experts appointed by the UNFCCC CDM (United Nations Framework Conventio n on Climate Change Clean Development Mechanism). He has offered trainings in Chile\, Qatar\, UAE\, Malaysia and India in power system protections\, stability and control topics. He has developed and validated a prize winn ing 68-bus power system model\, which now forms a part of IEEE Benchmark S ystems as a standard for researchers to validate their innovations in stab ility analysis and control design.
