Socioeconomic factors are the main factors affecting pumped storage power generation, followed by energy structure. Under the “30·60” 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.
Second, the energy storage operation model of the power supply side under the high proportion of wind power access is established, and the impact of new energy access on the system balance and energy storage configuration is explored.
Reveal the current regional competition pattern that pumped storage power generation is facing. Pumped storage power generation is mainly distributed in central-east regions, with an unbalanced spatial distribution. Socioeconomic factors are the main factors affecting pumped storage power generation, followed by energy structure.
Reasonable planning and construction of pumped storage power stations, to circumvent the uneven spatial distribution of pumped storage power generation (PSPG), can provide effective support for the stable operation of the power system.
Economic development relies on electricity, and early pumped storage construction was demand-oriented, with the core role of “peak adjustment and valley filling”, i.e., lowering the peak load of the grid, increasing the load in the low valleys, and maintaining the stability of the grid to make its operation more economical.
In summary, three main factors have the greatest impact in the reliability upgrade: parallel redundancy, low voltage and cell capacity. For each modular BESS based application, the impact has been quantified as follows: Energy application: The inclusion of modular parallel redundancy increases the reliability up to 21.78 %.
