| Summary: | Under the guidance of the "double carbon" goal, renewable energy has witnessed rapid growth in accommodation demand. In order to realize the complementary advantages of microgrid and renewable energy in the county and improve the accommodation rate of renewable energy, a ADMM-based interactive operation strategy for multi-scenario county-level multi-microgrid is proposed. Firstly, a scheduling model for independent microgrid operation is established to realize the optimal scheduling strategy in the day-ahead pre-scheduling plan. Secondly, a multi-microgrid energy interactive operation model is established, which is iteratively solved with the ADMM algorithm to obtain the global interactive energy between microgrids. Finally, the Shapley value method is used to allocate the benefits of the microgrid group and reduce the system operation cost of each sub-microgrid. The case study shows that the proposed method can not only improve the accommodation rate of renewable energy and realize the economy, but also reduce carbon emissions and realize low-carbon operation. |
