In this paper, the power structure, the peaking capacity of the power grid and the impact of wind power on the peak shaving capacity are comprehensively studied. At the same time, considering the volatility of load and wind power, a joint planning model of pumped storage-nuclear power-wind power installation is constructed.
Advantages of pumped storage hydropower. High volatility between on-peak/off-peak electricity prices drives energy arbitrage opportunities. Pumped storage is often considered the only proven grid-scale energy storage technology. A strong push for "carbon free generation" creates immense demand for energy storage products.
