Energy Management on Grid Connected Hybrid Renewable Energy Sources using Fuzzy Logic

Abstract

Renewable energy, such as wind, solar energy, is desirable for power generation due to their unlimited existence and environmental friendly nature. This paper deals with system integration and fuzzy logic based controller design for power management of a grid connected Hybrid renewable energy source (HRES). The hybrid system is the combination of photovoltaic (PV) array, wind turbine, and battery storage via a common current source interface multiple-input dc-dc converter. This converter is used to integrate the renewable energy sources to the utility grid. A two- level control system is implemented, comprising a Fuzzy logic controller, which ensures the power management between intermittent RE generation, energy storage, and grid, as well as local controllers for the photovoltaic, wind unit. Simulations are performed in MATLAB/Simulink.
