Efficient Power Management of Grid operated MicroGrid Using Fuzzy Logic Controller (FLC)

Abstract

The exponential increase in electrical energy demand in the current scenario makes the world to turn towards the use of renewable energy sources naturally. The best way to utilize the renewable energy sources is in the form of microgrid. Microgrids are having multiple distributed energy sources and energy storage elements located nearer to the consumer. This paper implements a Fuzzy Logic Controller that efficiently manages the loads in a grid operated Microgrid. In this paper, maximum power point tracking (MPPT) with fuzzy logic controller is used for a grid operated microgrid constituted by solar system and battery. The system consists of Photo Voltaic (PV) system with MPPT controller, Battery with Buck boost converter, Inverter, critical and non-critical loads and utility grid. The simulation results prove that the efficiency of the fuzzy logic controller for different irradiation level with different load conditions has been improved.
