A novel Grid Forming Controls (GFM) model in PSS/E for 100% renewable power grid
A technical presentation on the topic 'A novel Grid Forming Controls (GFM) model in PSS/E for 100% renewable grids'. Increased proliferation of Inverter Based Resources (IBRs) and retirement of conventional power generation has resulted in depleted short circuit levels and has raised stability concerns in operating electric grids. Majority of the IBRs today are Grid Following (GFL) meaning they require a voltage and frequency reference for their Phase Locked Loop and 'follow' and latch onto, in order to inject current to the grid. As short circuit levels drop, GFLs suffer from instability raising concerns. Grid-forming inverters (GFMs) are a promising solution in this regard as they behave as voltage sources behind an internal impedance, providing both voltage and frequency regulation. This talk will focus on a novel positive sequence model developed in PSS/E that has several levels of control that works in both grid connected and islanded mode of operation. Alongside an outer layer that generates Voltage and Frequency reference, a V-Q, P-F droop based current controller is utilized eventually form a voltage source interface. Simulation results will be shown that demonstrate stability in 100% renewable grids. During this presentation Tamojit present his work on GFM.
We invite all those interested in clean energy and the future of our renewable grid to join us for this insightful session.

Biography:
Tamojit Chakraborty works as a Senior Studies Engineer at Siemens Energy, UK. He holds a Masters degree from Arizona State University and has previously worked at Mitsubishi Electric and Electric Power Engineers. He has over 8+ years of experience and specializes in modelling of renewable (Wind, Solar, BESS, Hybrid Plants) and conventional generation in both RMS (PSSE, PSLF, TSAT) and EMT (PSCAD) domain. He has performed generator interconnection and grid code compliance studies as a power systems consultant. His expertise includes custom model development in PSSE and PSCAD. Recently, he has specialized in HVDC studies for grid access, particularly for offshore wind projects, performing dynamic performance studies, modeling, and simulations in PSCAD.
