Abstract:

In recent years, Henan Province’s power load, power supply structure and the pivotal position in the national power grid have undergone tremendous changes. In 2016, the maximum load has reached 52.08 million kW. The structure of  power supply has been transformed from depending mainly on thermal power into basing on the coexistence of thermal power and external adjustment. Henan power grid begin to become the thermal power center for central China power grid and the hub for interconnecting Northwest, North China and Central China power grids, the three major regional power grids. The original pumped storage power stations cannot meet the need of power development.  In order to ensure the safe and stable operation of the power grid, it is urgent to replan the layout of pumped storage power stations in Henan Province. It makes relevant discussion and recommendations.
