Hybrid Stand-Alone Photovoltaic/Batteries/Fuel Cells System for Green Cities

Abstract

In this paper sizing, simulation and optimization approach has been used to study the power management of a stand-alone hybrid PV/batteries/Fuel Cell power system. The main objective is to optimize and develop control strategies of a hybrid stand-alone power system to meet the desired electric load of a residential community energy to achieve cost effective and ecosystem friendly solutions for green cities. The chosen city is located in Bejaia region, a coastal region in the east of Algeria. Proposed Photovoltaic system with batteries and Fuel cells is used to produce energy without interruption. Hydrogen is generated by electrolysis process powered by excess energy of the system. An application is made for two days at Bejaia region supplying a residential house and the obtained results show that the proposed system using solar PV, batteries and Fuel Cell energy systems integrated with an electrolyzer for hydrogen production offers the best performance. Simulation and results were done under Matlab/Simulink environment.
