Non-iterative Coordinated Dispatch of Virtual Power Plant-Transmission Network Considering Time-period Decoupling
摘要
Abstract
A coordinated dispatch model of virtual power plant(VPP)-transmission network based on the feasible region equivalent projection theory can avoid iterative solving,thereby ensuring solution stability.However,with the large-scale integration of energy storage systems,time-period coupling constraints decouple the VPP feasible region into a high-dimensional space,significantly increasing the difficulty in characterizing the feasible region.Therefore,a non-iterative coordinated dispatch method of VPP-transmission network considering the decoupling of time-period coupling constraints is proposed.First,the epigraph theory is applied to eliminate internal variables of the VPP in the objective function,thereby reducing model complexity.Second,Lyapunov optimization is used to decouple the coupling constraints,and the vertex searching method is employed to characterize the equivalent projection of the VPP feasible region.Finally,the original VPP model is replaced by this feasible region projection to participate in transmission network dispatch,achieving the non-iterative solution for the VPP-transmission network coordinated dispatch model.Simulation results demonstrate that the proposed method can significantly improve the characterization efficiency of equivalent projection of the feasible region and ensure that the non-iterative coordinated dispatch achieves the same optimality as the integrated dispatch.关键词
