Optimum Size of Battery-less Energy Sources Autonomous Hybrid Power System for Water Pumping Applications

Abstract

The main target of this research is to study the techno-economic performance indicators of a battery-less photovoltaic/ wind turbine generator autonomous hybrid power system (PV/ WTG - AHPS), applied irrigation system to pump underground water. HOMER software package is used in the data analysis. A numerous amount of data samples were thoroughly investigated to choose the best overall configuration, with respect to the least net and flat rate of energy cost. A case study was undertaken on a pilot isolated agricultural project in Alminia city in Egypt. The findings appear to be well substantiated and supportive to the conclusion that the suggested combination of the PV/WTG-AHPS with 27 kW of PV arrays, 10 kW rating of a wind turbine generator, 14 kW sized power converters and 450 m3 storage water tank was found to be the most optimal system configuration for 15 kW peak AC submersible pump with average 110 kWh/day load demand.
