Closed-Loop V-f Control Strategy for PV-Battery Energy Storage System in Stand-Alone Microgrid

Abstract

The colossal increase in energy consumption owing to modern day’s lifestyle has led to the need for penetration of alternative sources of energy. Due to low inertia, microgrid may prone to several disturbances due to various unforseen conditions, which results in unstability. A glimpse of this paper encapsulates the two-stage integration of P–V array in stand-alone microgrid with integrated V-f controller to generate a pulse width modulation (PWM) signal to inverter’s gate. It is basically a close loop strategy to stabilize the system under several malicious content caused due to increase in demand or due to faults with less oscillation, an effective battery energy storage system is also designed to enhance the efficiency of the system. The overall model is simulated in MATLAB Simulink, and the results clearly validate the overall strategy.
