Spatiotemporal distribution pattern and analysis of influencing factors of pumped storage power generation in China

Under the "30 & sdot;60" dual carbon target, the construction of pumped storage power stations is an important component of promoting clean energy consumption and building a new type of power system. This article aims to depict the spatiotemporal distribution pattern and main influencing factors of China's pumped storage power generation (PSPG) and provides practical support for planning power station construction and promoting clean energy development in the future. The main conclusions can be drawn as follows: (1) From 2012 to 2020, PSPG was mainly distributed in the central and eastern regions, with an inverted "U" trend in power generation except for in Guangzhou and Zhejiang provinces. (2) The development direction of PSPG showed a fluctuating and spreading trend from East China to North China, but the development focus was still in East China. In addition, the western regions showed a low-low autocorrelation, while the central and eastern regions showed a high-high autocorrelation, highlighting the issue of spatial imbalance. (3) Socioeconomic factors were the main factors affecting PSPG, followed by energy structure, and the impact of natural factors was relatively weak.
