Dynamic Partitioning Based Reactive Power Optimization Method for Distribution Network with Renewable Energy and Energy Storage

This paper proposes a dynamic partitioning based reactive power optimization method for distribution network. Firstly, the reactive power regulation characteristics of different devices are analyzed, the modularity function expression in the power system is derived, and a dynamic partitioning strategy for the distribution network is proposed. Next, a mathematical model for multi-objective optimization of distribution network is established, and an improved particle swarm optimization (PSO) algorithm is proposed. With the proposed improved PSO, a multi-objective power optimization control strategy for distribution network is proposed. Finally, the effectiveness of the proposed control strategy is verified through simulation.
