摘要：In recent years, with the development and application of distributed generation, multi-microgrid structure has gradually become a future development form. However, new challenges have been brought to optimal operation due to its structural dispersion, complex composition, and information barrier. This paper proposes a distributed optimal operation model and solution method based on alternating direction method of multipliers (ADMM) algorithm. The original problem is decoupled into several independent sub-problems including distribution network and microgrids. Based on the second-order cone relaxed power flow model and the chance-constrained method, the model is optimized to realize the optimal operation of a distribution network with multi-microgrid. Finally, a case study is presented based on the modified IEEE33 node system, and the result illustrates the feasibility of the ADMM algorithm and it is applicable to optimize the operation of distribution networks with multi-microgrid.
