Optimizing the location and capacity of various flexible resources is an important technical route to achieving the goals in the construction of dual carbon and new power distribution system. Therefore, considering the economy and safety of planning operation, a two-stage coordinated planning method for renewable distributed power supply (DG), soft open point (SOP) and energy storage (ESS) of an active distribution network DG is proposed considering violation risk. In stage 1, the location and capacity of DG, SOP and ESS are optimized with the objective of minimizing comprehensive cost and violation risk. Stage 2 is multi-objective operation optimization combining SOP, network reconstruction, on-load tap changers, capacitor banks, demand response and energy storage. The hybrid method of the LDBAS algorithm based on grey target decision technology and second-order cone optimization is used to analyze the planning model. The proposed two-stage model is simulated in the IEEE-33 bus system, and the result proves that the coordinated planning model can effectively improve system operational efficiency, enhance flexibility and reduce operational safety risks and economic costs.
