Utilization of Energy Sources in Hybrid PV/FC Power Assisted Water Pumping System

In this paper, the mathematical analysis of solar photovoltaic (PV) system and proton exchange membrane fuel cell (PEMFC) system is presented. The renewable energy (RE) sources e.g. PV system and PEMFC are integrated for hybrid PV/FC power generation. The PV system is considered as primary electrical power generating RE source, and the PEMFC is utilized as power backup source in unfavorable environmental conditions of PV system. Furthermore, in cloudy days, the solar PV system is not capable to generate sufficient power to the load applications due to this a PEMFC can be utilized for power generation.

For transient analysis of this hybrid PV/FC power generating system, a water pump load is considered. A Fuzzy logic based maximum power point tracking (MPPT) technique is proposed to achieve maximum power point (MPP) through the PV system. A three phase induction motor (IM) is taken for water pumping system (WPS) application and the complete proposed system is designed in MATLAB/Simulink environment.
