Fuzzy Logic Control for Solar based PV-Battery Storage System with MPPT Technique

Abstract

Renewable energy sources like solar and wind are getting more research attention as a result of technological breakthroughs in these fields and a corresponding decrease in price. Due to its widespread availability, solar energy promises to be a sustainable answer to rising demand. However, the sun irradiance's unpredictable nature creates practical difficulties. This paper describes the control of a solar and battery storage based micro-grid in grid linked mode to meet the requirement for optimal coordination. The maximum power point tracking (MPPT) control is a feature of the PV array. Battery storage and charge controllers are dotted across the micro-grid to sustain erratic solar generator output. The FUZZY control mode is used to run the grid-side inverter. The Simulink Environment in MATLAB was used to create the model. The two instances of constant load and variable irradiance and variable load and variable irradiance have both been studied. The outcomes clearly demonstrate the effectiveness of the control strategy in preserving the balance of voltage, frequency, and power at PCC.
