摘要：
The access of large-scale distributed generations resulting great challenges to the structure, operation procedures, control methods and protection configuration of traditional distribution network. In order to solve the problem of centralized management and optimal control of large-scale distributed generations, energy storage systems and multitype loads in distribution network, a distributed active and reactive power optimization control method for active distribution network was proposed in this paper. Firstly, the active distribution network was divided into several regions. The goal of maximizing the distributed generation consumption, minimizing the grid voltage deviation and the network loss in different regions was set up. The sub-optimization model of each region was established. Then, according to the boundary information exchanged between adjacent regions, the sub-models of each region were solved by accelerated alternating direction method of multipliers (A2DM2). After iterative calculation, the approximate global optimal solution is obtained, which realizes the decoupling of active distribution network and the distributed control of each region. The proposed method can not only ensure the operation economy of active distribution network, but also improve the voltage quality of power grid and the self-consumption level of distributed power supply. Meanwhile, the impact of power reversal on the upper-level power grid are reduced. Finally, the effectiveness and feasibility of the proposed method are verified by simulations. © 2020 Chin.
