Expected to 2020, China Southern Power Grid (CSG) installed capacity of pumped‐storage power plant (PSPP) will reach 7,880 MW. This paper summarises the operation situation and describes the main functions of PSPP in CSG, mainly Guangzhou PSPP and Huizhou PSPP. According to the characteristic of Guangdong power system, various functions such as peak‐valley load regulation, frequency control, phase shifting, emergency reserve, and black start‐up of PSPP are studied here. At the same time, this paper points out the existing problems, such as economic operation of PSPP in CSG needs to be optimised and presents corresponding proposals for improvement.
