PERFORMANCE ANALYSIS OF STABILITY AND VOLTAGE CONTROL USING P-F AND Q-V DROOP CONTROLLER FOR AN AUTONOMOUS AC MICROGRID

Abstract

The present scenario structure of grid accommodates complex network which increases instability. At the
same time, a small scale generating units using renewable energy sources is rapidly increasing. The increase in
renewable energy source brings the concept of distributed generation and micro grid in the research area. These
Distributed Energy Resources are interfaced to the conventional micro grid via power electronics converter. Hence these
converters bring the problems of power quality and stability. Hence in this paper the performance analysis of DG are
focused .To analyse the stability of the micro grid P-F and Q-V droop controller are used. The simulation was done in
MATLAB/Simulink Sim power system software.
