Research on Three Engine Pumped Storage Units with a Water Head of over 800 Meters
China's resource endowment is characterized by rich coal,poor oil and low gas,which makes China's energy structure mainly based on fossil energy.Under the guidance of the"double carbon"goal,the new energy system with non-fossil energy as the main body is bound to be the general trend of the future,and photovoltaic and wind power have become the main force of new energy under the new energy system,but photovoltaic and wind power have randomness and volatility,and the impact on the power grid is relatively large.In order to efficiently absorb and absorb the main power supply of photovoltaic and wind power in the future,avoid the waste of new energy,and ensure the safety of the power grid,the pumped storage hydropower station will inevitably be the main force of energy storage in the future,and the three engine pumped storage units has more unique energy storage advantages,including a wider range of application of the head,a wider amplitude of the head,a faster response to the power grid,and a lower project cost.Combined with the actual situation of photovoltaic and wind power,this paper discusses the new energy storage scheme under the main force of photovoltaic and wind power,and the research and exploration of high-quality consumption of new energy by three engine pumped storage units.
