Abstract
This paper indicates that the AC Microgrid consists of four different distribution generation sources a Solar PV array, a DFIG-based wind energy conversion system, and a hydro and diesel generator power station. During the disturbance in grid utility and generation of renewable power is not enough than diesel generators are used to meet the load demands. Diesel generators are used as an emergency power source. This paper examines the impact of the implementation of different power system stabilizers on renewable-based DGs wind (DFIG) and PV and also on diesel, hydro power synchronous generators of grid forming AC Microgrid. Various PSSs like local or conventional PSS controllers, multi-input based MBPSS controller, and Linear Quadratic Gaussian (LQG) controller are implemented on hydro, diesel generators, DFIG, and Solar PV systems of the AC microgrid for the elimination of electromechanical oscillation in distributed generation. The performance of different PSSs is compared by simulation of grid-connected AC Microgrid by using MATLAB/SIMULINK software. The simulation result demonstrates the performance of the LQG Controller over conventional PSSs and MB-PSS Controller under fault conditions.
