SVPWM based double loop control method of a three phase inverter for Microgrid Application

Abstract

Many AC Microgrids required an inverter for converting power from DC to AC. Many control techniques are available and need a flexible control method which can able to regulate both the voltage at DC and AC side. The DQ method is developed in this paper by incorporated with space vector pulse width modulation (SVPWM) technique. A distribution generator (DG) is considered in this paper for connecting to utility grid through an inverter controlled by proposed double loop control technique. One voltage controlled loop and one current controlled loop are used in proposed control method to regulate both voltage and current. This paper showcases comprehensive findings using MATLAB/Simulink.
