PRELIMINARY EVALUATION TOOLS FOR WIND-PUMPED STORAGE ENERGY GENERATION SYSTEM

Abstract

Energy demand never ceases to increase with larger cities, urbanization and migration to the cities. However, supplying the remaining and important rural areas with electricity remains costly. Exploring the off-grid energy generation is therefore a promising solution. After an exhaustive qualitative evaluation on different energy generation system, this study has chosen the Wind-Pumped Storage Hybrid (WPSH) system to be evaluated. A simulation tool was built to take the wind energy and convert it into pumping power to store water in a reservoir that will supply a hydro-turbine, generating electricity to a domestic area. A preliminary evaluation was done in Kajang for a selected day of July 20 2020. The result shows that the wind fluctuations and energy demand fluctuations affect the WPSH system’s capability to deliver sufficient energy through 24 hours. During the day, the amount of water accumulated in the reservoir is insufficient to meet the energy demand. It is only after 7.00 p.m that the system will be able to meet the demand and reserve a surplus of water in the reservoir.
