New pumped storage power station operating in joint with chemical energy storage and clean energy system
In this paper, a new type of pumped storage station with faster response speed, wider regulation range and better stability is proposed.The flexible operation level of the traditional pumped storage power station can be improved by the variable speed pumped-storage technology.Combined with chemical energy storage, the failure to second-order response speed and the insufficient safety reliability of pumped storage power unit could be solved.With the better solar energy and site resources, the integrated performance can be improved by the optical storage system installed in the future pumped storage station.Through the characteristics analysis of the new type pumped storage power station, three kinds of optimal station locations are proposed, namely, the load concentration area, the new energy concentration area and the ultra high voltage direct current (UHVDC) receiver area.Taking the new pumped storage power station as an example, the advantages of multi-energy cooperation and joint operation are analyzed.It can be obtained that the frequency and load regulation of power grid will be more flexible, and the service capacity to the main power grid is much stronger in the future.
