摘要：
Aiming at the urban distribution system including multi-type microgrids, a distributed cooperative optimal scheduling strategy is proposed for urban distribution systems considering the demand response characteristics of multi-type microgrids. Through the coordination of power interaction among the multi-type microgrids and distribution networks, as well as the power of internal equipment in multi-type microgrids, the overall operation costs of urban distribution systems including multi-type microgrids are reduced. Firstly, the energy consumption characteristics of multi-type microgrids are analyzed, which include industrial microgrids, commercial microgrids, and residential microgrids. Then, an optimal scheduling model for urban distribution system including multi-type microgrids is constructed considering both the economy of multi-type microgrids and the distribution networks. In order to preserve the privacy information between each entity and reduce the influence of prediction information inaccuracy on the optimization results, a distributed solving method based on rolling optimization is proposed. Finally, by comparing the case study results in different scenarios, the effectiveness of the proposed model and algorithm in improving the operation economy of each microgrid and distribution system is verified. © 2022 Automation of Electric Power Systems Press.
