Source Load Interval Coordinated Scheduling of New Energy Grid with Load Fluctuation

Abstract

Abstract In order to reduce the impact of load fluctuation brought by new energy interconnection, the operation cost of power grid is increased. Considering the characteristics of load fluctuation, this paper studies a new energy grid source load interval coordination scheduling method. Based on the characteristics of source load fluctuation and demand side load fluctuation of new energy grid, the dispatching principle is established. In this paper, the flexible operation region of new energy grid is calculated, and the target function of power grid source load interval is constructed. Numerical results show that the proposed method can improve the economy of energy storage unit and power system, and the comprehensive benefit is positive in different scenarios.
