Classification of hydropower stations? If it can be divided into energy storage and the like, be specific! Online, etc

There are many classification methods for hydropower stations. According to the nature of water resources used by hydropower stations, they can be divided into three categories:

① Conventional hydropower station: using natural rivers, lakes and other water sources to generate electricity;

(2) Pumped storage power station: when the power grid load is low, the surplus power is used to pump the water from the lower reservoir to the upper reservoir for storage, and when the power grid load is high, the water is released for power generation, and the tail water is discharged to the lower reservoir to meet the needs of power grid load such as peak shaving;

(3) Tidal power station: use tidal energy formed by tidal fluctuation to generate electricity.

According to the utilization mode and regulation capacity of natural water flow, hydropower stations can be divided into two categories:

(1) Radial-flow hydropower station: a hydropower station with no reservoir or small reservoir capacity and no or little regulation capacity for natural water;

(2) Reservoir hydropower station: a hydropower station with a certain storage capacity and different regulation capabilities for natural water flow.
