Benefit Analysis of Pumped Storage Power Station in East China Grid under the New Power System
With the strategic context of promoting sustainable development and achieving the goal of"carbon peak and carbon neutrality",building a new power system is an important measure.As the core component of the new power system,pumped storage plays an indispensable role in promoting the efficient consumption of clean energy,replacing system capacity,saving coal and reducing emissions,and other dynamic benefits.With the increase in the proportion of external power and non-adjustable power sources in the region,the demand scale of East China Power Grid for pumped storage has further increased,and the operation mode and function efficiency of pumped storage power stations have also adjusted.In this paper,by constructing a simulation model of power system production and operation,considering the similarity of power grid structure in various provinces and cities of East China Power Grid,taking Anhui Power Grid as an example,the typical constraints and optimal objective function method are used to carry out power balance analysis.The results show that in the power grid with large installed capacity of thermal power and lack of primary energy,the construction of reasonable scale pumped storage power stations plays a great role in promoting new energy consumption,providing capacity,and saving coal and reducing emissions.
