Economic Analysis of Deep Peak Shaving Renovation of Thermal Power in High Proportion Renewable Energy Power System
With the large-scale penetration of renewable energy,the pressure of peak shaving in the power sys-tem is increasing.Therefore,timeseries production simulation is used to simulate the established model,with the economic optimization of coal-fired power generation cost and unit start/stop cost as the objective function,and then constraints are established around the objective function.The results show that the benefits of retrofitting the unit itself are much higher than adding energy storage devices,and the reduced cost of starting and stopping the unit is much higher than the benefits of renewable energy generation.
