As an important development direction of the active distribution network, it is of significant research value to coordinate the active-reactive power resources of the AC/DC distribution network for improving the characteristics of system operation. First, taking the AC/DC distribution network based on multi-terminal soft open point (SOP) as the research object, an active-reactive power dispatch model of the AC/DC distribution network is constructed with the objective of minimum operation cost considering the key equipment operation constraints for the energy storage, flexible load, SOP, photovoltaic inverter, and the constraints of peak-shaving and valley-filling and voltage offset. Secondly, in order to adapt to the uncertainty of photovoltaic output, a data-driven two-stage stochastic-distributionally robust optimization model is constructed. Then, the model is solved based on the column and constraint generation algorithm. Finally, the 72-bus and 38-bus AC/DC distribution networks are used to verify the effectiveness of the proposed model.
