The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.
The bidding strategy of energy storage power station formulated in most papers relies on the day-ahead predicted price and regulation demand, and the effectiveness of the bidding strategy is based on the premise that day-ahead forecast is accurate [9, 10, 11].
In recent years, battery energy storages stations (BESSs) account for the largest proportion in large-scale energy storage power station projects due to its advantages such as rapid response, high integrated power, decreasing cost year by year and short construction cycle.
It is a tool for power conversion and reserve. At present, the comprehensive efficiency of the PSPS is about 75% (the ratio of power generated to power consumed) in China, which is also called "using 4 degrees to produce 3 degrees”. The PSPS is the best tool for energy storage.
The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.
1. Introduction The PSPS is a special hydropower station, which can use the electricity to pump water up to the upper reservoir when the energy demand is low, and release the water back down to the lower reservoir to generate electricity when the energy demand is high.
