Abstract:
When the distributed power supply is connected to the distribution network, the local voltage of the distribution network exceeds the boundary and the network loss increases. In this paper, an active-reactive coordinating voltage control method is proposed. Aiming at minimizing network loss and voltage deviation, the explosion generation mode, mutation rule and selection strategy of the traditional fireworks algorithm are improved, which improves the convergence speed of the algorithm and enhances the global search ability. It is used to solve the IEEE33 node system with distributed photovoltaic generations, and the performance of maintaining voltage stability and reducing power loss of the proposed method is verified.
