| Summary: | With the rapid development of various load side resources such as adjustable loads and electric vehicles, how to accurately regulate them has become an important research point. In order to give full play to the regulation ability of flexible loads in distribution networks, a hierarchical cluster regulation method for flexible loads in distribution networks based on improved alternating direction multiplier method is proposed. Firstly, the flexible loads are clustered hierarchically using the BIRCH clustering algorithm. Secondly, based on Nash negotiation theory, the original problem is decomposed into two sub problems: cost minimization and revenue allocation, and a flexible load cluster regulation model for distribution networks is established. Then, an improved alternating direction multiplier method is proposed by introducing an adaptive variable parameter acceleration factor. Finally, a simulation example is used to verify the effectiveness of the proposed method. The results show that the proposed method can effectively achieve cluster regulation under access of large-scale flexible loads, and its convergence performance is better than the conventional methods. |
