Fuzzy Logic Based PV-Battery system for a Standalone Microgrid

Abstract

This paper proposes a standalone microgrid in integration with photovoltaic array and battery storage system based on fuzzy logic MPPT technique. Solar PV systems are affected by variables like temperature and irradiance and have nonlinear I-V characteristics. Fuzzy logiv MPPT can handle nonlinearities better than any other conventional MPPT technique. in addition with the battery storage system the microgrid can be operate in both islanded mode and grid connected mode. To simulate this system with Solar PV and battery storage system MATLAB Simulink is used. This model can be used more efficiently for remote locations or villages where electricity supplies are not present or it gets affected by too much load shedding. Microgrids in integration with the renewable sources is the future for electrical power generation.
