Hybrid Renewable based Dc Micro grid using Fuzzy Control Technique for Energy Management System

Abstract

This concept proposes an approach for the hybrid renewable base in Energy management for stand-alone applications. Energy charging process is non-linear, time-varying with a considerable time delay so it is difficult to achieve the best energy management performance by using traditional control approaches. A fuzzy control strategy for battery charging or discharging used in a renewable power generation system is analyzed in the paper. To improve the life cycle of the battery, fuzzy control manages the desired State Of Charge (SOC). A fuzzy logic-based controller to be used for the Battery SOC control of the designed hybrid system is proposed and compared with a classical PI controller for the performance validation. The entire designed system is modelled and simulated using MATLAB/Simulink Environment. The proposed concept can be implemented to fuzzy control technique using MATLAB/SIMULINK software.
