Pumped storage plays an important role in promoting the optimal allocation of power generation resources and maintaining the safe and stable operation of power grid. Reasonable pumped storage dispatch mode can maximize the operating income and system benefits of operators. The United States has mature experience in power market mechanism and pumped storage dispatch mode. This paper mainly sorts out three dispatch modes of pumped storage in the American power market environment: self-dispatch, semi-dispatch and full-dispatch, compares and analyzes the specific practices and application areas of optimization objectives, operation constraints and optimization benefits. Besides, the paper analyzes the differences and reasons of optimization results under the three dispatch modes through an example of joint dispatch of pumped storage and thermal power units in a given region. Finally, based on the summary of the pumped storage dispatch mode in the United States, the paper puts forward the enlightenment of pumped storage dispatch mode in power market environment in China.
