【 摘 要 】

With the growth of electrical load and development of clean energy, peak regulation of power system has been paid more attention to, in which case pumped-storage plant becomes the most efficient and economical way against peak load and the ensurance of safe and stable system operation. However, the dispatch and operation mode of pumped-storage plant is a little unreasonable at present in our country, due to the insufficient acknowledge of plants' function orientation in different regions. This paper studied the standard of classifying pumped-storage plants, by dividing the plant function into three types security oriented, peak shaving oriented and renewable energy accommodation oriented, based on the local load characteristic, structure of power supply, accommodating capability of renewable energy, nuclear energy, etc. Finally, according to the current and future development situation of five Chinese regions, the function orientation partition of pumped-storage plant is given, which has profound guiding and practical significance for pumped-storage plant dispatch and operation.
