Robust Optimization Configuration of Pumped Storage Power Station Capacity Considering Source Load Uncertainty
In response to the capacity configuration problem of pumped storage power stations in wind solar thermal pumped storage combined power generation systems,an economic operation model of the combined power generation system is established.The model aims to minimize the amount of wind and solar waste,minimize the system's power generation cost,and minimize the construction and operation costs of pumped storage power stations.Considering the uncertainty of new energy output and load in the system,a two—stage robust optimization model with a min max min structure is introduced to obtain the minimum operating cost of the system in the worst scenario of new energy output and load.The capacity of pumped storage power stations is determined based on the minimum operating cost.Using actual data from a city level power grid,the model was solved based on column and constraint generation algorithm.The calculation results verified the effectiveness of the model and algorithm,providing reference for the planning,construction,and operation of the system.
