ANFIS based control strategy for frequency regulation in AC microgrid

Abstract

Driven by the present day environmental concerns, distribution generation sources for electricity generation is increasing at a rapid pace. This makes a fundamental creation of microgrid as changing nature of distribution generation sources changes the quality of generated power. To avoid adverse effects of the unpredictable variations in RES many control concepts have been proposed in literature. This work considers autonomous mode of AC-microgrid. Under the effect of sudden changes in load and wind speed variation, the ANFIS scheduled PID controller is proposed and its comparative performance analysis is also shown. The simulations are carried out using MATLAB® the results of which show a ANFISPID controller behaves less oscillatory behavior.
