Under the "dual carbon" goals, the large-scale integration of distributed photovoltaic (PV) systems into the distribution network introduces new issues and challenges for active-reactive power optimization. This paper proposes a coordination optimization strategy for active-reactive power in distribution networks, considering the siting and sizing of reactive power compensation devices. The strategy first involves optimizing the placement and capacity of Static Var Compensators (SVCS), which significantly reduces overall investment and operating costs. Subsequently, an active-reactive coordination optimization model is established for the distribution network, aiming to maximize distributed PV accommodation, minimize daily operational network losses, and minimize voltage deviation at PV grid connection nodes. The optimal operational strategies for PV, energy storage, and SVC are obtained. The improved particle swarm optimization algorithm is used to solve the model, and the optimal operation strategy of PV, energy storage and SVC is obtained. Finally, the effectiveness of the proposed strategy is validated through case studies conducted on the IEEE 33-bus system. This optimization strategy not only reduces operational costs and curtails PV curtailment but also enhances the coordination between active and reactive power within the system.
