Abstract

This paper studies the design and performance of a WES / PFCS hybrid electrical power system. This system consists of Wind Energy System, WES, and Pem fuel cell system PFCS. The design of this system depends on the hourly energy balance technique. When the power output from WES, Pew , exceeds the load demand, PL , the exceed power used
by the alkaline electrolyser to produce hydrogen . Then the H2 is compressed and stored in pressurized storage tanks. Also, when Pew < PL this means that there is deficit power and the stored H2 is utilized for generation electrical power by the PFCS to overcome the deficit on the system. The methodology which developed here has been applied on EL-Zafarana site as a case study. EL-Zafarana is a remote site located at the coast of the red sea, Egypt.
