Abstract:
Microgrids are much capable to meet power demand locally. However, its reliable and secure
operation with the existing network does require a thorough evaluation of associated technical risks
and their effective rectification schemes. A self-excited induction generator (SEIG) wind-powered
microgrid (MG) has gained wide attention from researchers due to its constrained operating conditions. In the islanded mode of wind-powered microgrid, small disturbances and load variations in
the three-phase system can cause issues related to frequency and voltage imbalance. This research
is focused on technical limitations in terms of voltage and frequency. A control strategy based
on static synchronous compensator (STATCOM), pitch angle control (PAC) and energy storage
system is investigated and implemented for stabilization of microgrid transients during the island
for different scenarios i.e with and without control mechanism, tripping of any SEIG unit and isolation of common load. Simulations are conducted in MATLAB/Simulink and obtained results
demonstrate the effectiveness of the proposed control scheme.
