چکیده:

This paper presents a survey on the research and applications of the pumped storage based on the published papers in trying to provide a suitable picture of thedevelopment of this electric load regulation approach. Moreover, the paper summaries two separate pumped storage power plants projects, one in America(Seneca) and another in Iran (Siah Bishe) from the following point of view: 1-The operation of power plant generator/motor during day and night2-Introduction of starting system in motors state 3-Technical, economic and environmental aspects of such power plant4- Determination of system efficiency. Since there are some experiences with Siah Bishe power plant project, the performances of the plant in dynamic stability improvement of the network following asymmetrical short circuit is analyzed. Based on the obtained results, it becomes clear that the plant can have great effect on the recovery of the network dynamic and transmitted energy between the synchronous machines installed in the plant and thenetwork. High speed response is the most important factor which enhances the small signal stability of the system. This function of the plant can be critical in the faultevents.
