“…A new sensitivity index dV/dIR is employed to place STATCOM by replacing optimal capacitor in [17] to analyze the voltage recovery time for the generator and load buses and its effectiveness has been compared with the existing sensitivity index dV/dQ. The research in [18] represents that trajectory sensitivity index (TSI) based approach to improve FIDVR issues and post fault scenarios through optimal location selection for STATCOM. Due to high penetration of solar PV and induction motor loads the FIDVR related issues are minimized through a unique PV-STATCOM controller in [19].…”

Reliable and efficient power flow in the electrical grid is crucial given network expansion and the incorporation of numerous renewable sources. Microgrids are becoming more and more important in the global energy sector due to its numerous benefits. The variable nature of distributed energy resources (DER) in microgrid makes large-scale DER integration potentially unstable for system voltage. Grid regulations place restrictions on the voltage control of DER unit, which raises the need for reactive power support. Proper placement of flexible AC transmission system (FACTS) under post-fault conditions may enable faster voltage recovery. In this work, battery energy storage system (BESS) and static synchronous compensator (STATCOM) have been considered for improving the post-fault voltage in DER integrated weakly grid-connected microgrid system. Two operation scenarios have been considered for analyzing the behavior of BESS and STATCOM individually at post-fault situation. According to the results of the simulation, BESS requires lesser rating than STATCOM for faster recovery of post-fault voltage of the system.
