摘要：
It is an important problem for smart grid to guide flexible resources participating in the optimal operation of the power grid, and the zoning and diversifying of the AC/DC hybrid distribution network also bring about new challenges. A two-level optimization for the AC/DC hybrid distribution network considering the participation of flexible resources is proposed. Firstly, the flexible resources model on both the supply and demand sides is analysed. The peak and valley periods are divided and a reasonable TOU price is formulated by clustering the loads. The operation flexibility evaluation index is defined from the perspective of supply and demand balance. Secondly, considering the demand response, wind & solar uncertainty and other factors, a two-level optimization model of the AC/DC hybrid distribution network considering flexibility and economy is established. In this model, the upper level takes the flexible load scheduling strategy as the decision-making unit, and the lower focuses on the operation strategy of flexible supply resources and solves it by using the distributed robust optimization. Finally, the simulation results of an example verify the rationality and effectiveness of the proposed optimization. © 2022, Power System Technology Press. All right reserved.
