Research on Planning and Optimal Operation of Variable Speed Pumped Storage

Combining hydropower market economy and safe dispatching, the paper puts forward a mathematical model for optimal dispatching of variable-speed hydropower generating units, and an online transaction mode that takes into account energy saving and consumption reduction. The power generation sequencing method is determined according to the unit quotation method, and energy consumption indicators are introduced according to reservoir storage. Water volume, etc., adopt a differentiated power plan, open power generation rights trading, and adjust the trading market to ensure the economic benefits of hydropower plants while achieving the goals of energy conservation and environmental protection.
