Comparison of Archimedean Screw and Normal Pump in Pumped Storage Generation Combined with Wind Power Generation

Renewable energy resources such as wind energy have a disadvantage that the quality of output power is lower than that of fossil fuel resources. To solve this problem, pumped storage power system with Archimedean screw is designed. The structure and principle of operation are introduced and the advantages and disadvantages are discussed according to the theory and the simulation. In this paper, comparison has been done by collecting and analyzing the data and simulated the system on different condition to show the differences of the two types of pumps working on the pumped storage system.
