Concept of Accumulation of Energy from Photovoltaic and Wind Power Plants by Means of Seawater Pumped Hydroelectric Energy Storage

摘要

The article deals with the problem of accumulation of energy generated by wind and photovoltaic power stations. It notes that efficiency and reliability of electricity supply provided by wind and photovoltaic power may be achieved by using of back-up or storage power systems. There has been mentioned the ranges in cost of various electricity accumulation technologies. The authors consider the technology of construction a pumped-storage hydro power plant directly in the sea. Design parameters of storage reservoir of such hydro power plant have been estimated as well.
