Utilization of Solar PV Panel Arrays for Supply Part of Main Pumps Power Demand in a Typical Pumped Storage Hydro Power Plant

The small and medium scale pumped storage hydro power plants are very useful manner of power generation for safe supply of extra electrical power demand of some urban and rural areas during peak hours in many under development countries. But the electric power consumption of the main transfer pumps of these power plants, which usually work continuously about ۱۲~۱۶ hours on a daily basis, is a considerable amount of electric power that is usually supplied via the national cross country electrical power grid network. Usually, renewable energy sources utilization are more economic in “Hybrid” combination with other conventional electric power sources in under development countries. Otherwise, they have not significant chances to be utilized and effectively developed in these countries. In this paper, a typical ۱۰۴۰ MW nominal capacity pumped storage hydro power plant, with a total main pumps power consumption of about ۵۰ MW is studied for seeking opportunity for supply part of their electrical power demand via hybrid power generation of a series of solar PV panels (i.e., a small solar PV power plant) and simultaneous electrical power get from national cross-country power grid network. This study resulted that about ۱۲% of the main pumps power demand can be generated via a suitable design and proper arrangement of series of solar PV panel arrays.
