Robust Primary Control of AC Micro-Grid and Analysed Effect of Noise

Abstract

This paper investigates the effect of random measurement noise in grid connected microgrid. The primary control of grid-connected microgrid with four distribution generations (DG) units, is performed with and without measurement noise. The different power system stabilizers (PSSs) structures are utilized in primary control action for synchronous machine rotor speed and rotor angle control. The comparison of time-domain response having without any PSS, with conventional PSS (Delta Omega PSS and Delta Pa PSS), MB-PSS and robust Fuzzy Logic based PSS, is done. Using a typical test microgrid model, the performance of robust controller as a power system stability agent is accessed via time domain simulation of the
