摘　　要：蜂巢状有源配电网是一种通过规模化链接微网群,实现大规模分布式可再生能源高效接入的新型配网形态。针对蜂巢状配电网中微网群与互联基站协调运行机制复杂的难题,提出一种以系统运行成本最小为目标,基于多分块交替方向乘子法(block-wise alternating direction method of multipliers,BADMM)的分布式优化调度策略,有效克服了多基站与多微网之间协调运行的挑战。首先根据拓扑结构建立蜂巢状配电网的优化数学模型,然后以智能功率/信息交换基站为中心将蜂巢状配电网划分为多个区域,每个基站协调同步计算与其相邻微网的优化问题。最后通过算例验证了所提策略的有效性和收敛性,为大规模微网群的经济优化调度提供了参考。The honeycomb active distribution network is a new type of distribution network structure for large-scale microgrid clusters,which can realize efficient integration of large-scale distributed renewable energy.Aiming at the complex problem of the coordination operation between microgrids and smart power/information exchange stations(SPIES)in the honeycomb distribution network,this paper proposes a distributed optimal scheduling strategy based on block-wise alternating direction method of multipliers(BADMM)to minimize the operating cost.Firstly,a honeycomb distribution network optimization mathematical model is established according to the topology.And then the honeycomb distribution network is divided into multiple areas with SPIES as the center,and each SPIES coordinates and synchronously calculates the optimization problem of its adjacent microgrids,realizing the global optimization.Finally,the effectiveness and convergence of the proposed optimal scheduling strategy is verified by an example.
