Home Energy Management System Based on The Photovoltaic – Battery Hybrid Power System

Abstract

This paper introduces optimal energy management for a grid-connected photovoltaic - battery hybrid power system. Management of power flow is necessary to minimize electricity cost which subject to power balance, solar output, and battery capacity. The conditions of simulation model testing depend on the load profiles in each day and the energy unit rate with time of use rate (TOU) pricing. The simulation study cases consist of seven cases. The results show that the system with the PSO technique and the FLC application can reduce the energy cost in significantly. In addition, the simulation accomplished to verify the system usefulness to enhance home energy management system by reducing the peak demand.
