Fuzzy Logic Based Energy Management System for Grid Connected Solar PV System

Abstract

Expanding access to electricity continues to be a significant problem, especially in rural and remote areas, due to geographical and infrastructure constraints that impair power supply reliability. A sustainable solution for the same is the incorporation of renewable energy sources, including photovoltaic (PV) systems. However, the intermittent nature of solar put an emphasis on need of an efficient energy management system, to optimize generation and consumption. A rule-based fuzzy logic controller (FLC) for an energy management system (EMS) in a grid-connected photovoltaic system is proposed in this work. With the help of fuzzy logic control for intelligent decision-making, alternates between available power sources, maximizes energy extraction from renewable source generation, and reduces reliance on grid supply. This allows for effective power demand management, improves operational efficiency, contributes to economic and environmental benefits.
