Long and short term market competitiveness evaluation model of pumped storage unit

With the "double carbon" goal of our country, the electric power industry needs to build new power system with new energy as the main, vigorously develop wind power, photovoltaic and other renewable energy sources to accelerate the process of decarbonization, and pumped storage power station, as the most mature technology energy storage method in the world at present, has the characteristics of large capacity, fast response and high reliability. The construction will be accelerated to provide important support and guarantee for the safe operation of the new power system. In order to give full play to the advantages of pumped storage power stations, it is necessary to evaluate the competitiveness of pumped storage units reasonably, so that pumped storage power stations can better participate in the operation of the power market. In order to clarify the competitiveness of pumped storage units in the long and short term market, a long and short term market competitiveness evaluation model of pumped storage units based on the order graph-fuzzy comprehensive evaluation method is proposed to study what kind of power market is more suitable for pumped storage power stations to participate in.
