Pumped Hydro Electric Energy Storage for Rural Electrification.

      Аннотация: Nowadays, due to the ever increasing demand of electricity and the rise of environmental concerns, renewable energies are becoming the best option for electrification especially for rural electrification. The biggest problem of wider use of renewable energy sources is energy storage. This research deals with the pumping storage system analysis. The water reservoir serves for daily and seasonal energy storage, thus basically solving the energy storage problem. The electrical energy produced in excess by the renewable energy system is converted in potential energy by pumping water to a higher elevation where it can be stored indefinitely and then released to pass through hydraulic turbines and generate electricity. The estimation of energy demand for day and night time, stored energy, reservoir dimension and parameters of hydroelectric plant are presented.
