At present, the coupling of virtual power plant (VPP) and active distribution network (ADN) has been further deepened. Aiming at the optimal dispatching problem of ADN with VPP as a market participant, it is necessary to study the coordinated interaction between various flexible resources in ADN and uncertainty factors in VPP in different time stages. On this basis, with the goal of minimizing the comprehensive cost of ADN and maximizing the market revenue of VPP, a two-stage dispatching method for ADN considering VPP transaction is proposed. In the day-ahead stage, according to the flexibility boundary of the system, a bi-level optimization model is established considering the dispatching of flexible resources in ADN and day-ahead clearing of the VPP. On this basis, the bidding scheme of VPP and the operation strategy of ADN are adjusted in real time. Finally, an improved IEEE 33-node system is taken as an example for simulation analysis, and the results show that the proposed model can improve the market competitiveness of VPP and the operational flexibility of distribution networks both, which provides a reference for optimal dispatching under the future marketization development of power grid.
