Moreover, the existing methods of line loss optimization in distribution network have some problems, such as high computational complexity, low efficiency, and local optimality༎Therefore, a two-layer optimal configuration model of distribution network is constructed. The upper model determines the installation location and capacity of distributed power supply and energy storage by using the lowest economic cost of the system. The lower model establishes the optimal configuration model of wind-solar and storage integration by taking the active power network loss and voltage deviation as the objective function. Besides, the Improved Whale Optimization Algorithm (IWOA) was used to solve the optimization result in the upper and lower layers’ model. Based on the IEEE-33 node power distribution system, a simulation is conducted and the effectiveness and superiority of the model and algorithm are verified.
