Designing of Stand-alone PV/FC Hybrid System for Sale Electrisity

摘要

Development of renewable energy sources have shown perfect potential as a form of contribution to conventional power generation systems. This paper presents a hybrid system based on photovoltaic (PV) module and PEM (proton exchange membrane) fuel cell (FC) considering sale electricity to distribution network and improve its reliability. This paper presents a system that moreover supply the electricity of system load, capable to sale electricity to DN and by electricity injection causes DN reliability improvement. The revenue from selling electricity to DN is considered as the system profit (SP). An optimization to maximize the SP using GAMS environment is applied. Hourly optimal rate of sold electricity to the DN due to changes in solar irradiance, the optimal rate of PEMFC hydrogen consumption and stored hydrogen in the tank are determined. This study proves this claim that moreover load electricity provision, electricity can also be sold to DN by proposed hybrid system and by injection the electricity to DN was increased its reliability in consumers load supplement.
