Introduction
Within 5 years, the pumped storage power station will pump 2.09 billion kWh of electricity annually and generate 1.682 billion kWh of electricity annually. Figure 5. Power consumption/power generation of the pumped storage power station during 2018-2022 (billion kWh). The typical daily operation strategy of the power station is shown in Figure 6.
In terms of the pumped storage price mechanism, most of the existing studies focus on the price mechanism of pumped storage power stations at a certain stage, including the current two-part price mechanism and the bidding mechanism under the market environment, and the horizontal comparison of the multi-stage price mechanism is lacking.
In the operation strategy of pumped storage power stations, the operation model of pumped storage power stations in different countries is also different. The operation model of Japan’s pumped storage power station mainly includes a leasing system and an internal accounting system.
The total power generation duration of pumped storage is 8 hours, 6:00-8:00 and 18:00-21:00, respectively, generating 5008.27 MWh. The total pumping time is 7 hours, 1:00-3:00, 13:00-15:00, and 24:00 respectively, and the total electricity consumption for pumping is 6575.34 MWh. The energy conversion efficiency is about 76.17%.
