AI 中文摘要
大规模微电网通常由虚拟电厂聚合的多个跨区域子电网组成。当前基于共识的方案无法保证子电网间的差异化需求特性。本文研究由通信权重诱导的分布式集群共识控制来解决大规模微电网的经济调度问题，通过精心设计通信权重实现预期集群。设计了基于特征向量中心性的有向连通图通信权重矩阵设计方法，使通信网络邻接矩阵有给定主导特征向量，各集群代理有相同特征向量中心值。在此基础上设计分布式集群经济调度方案，即主从集群共识控制器，驱动边际成本实现多共识以在分布式电源间分配功率，VPP收集的各子电网功率缺额可按预定比例分配给公用电网以维持供需平衡。文中强调所用加权网络是有向连通的，且只有少数集群能访问主节点信息，还进行了相关仿真验证方案有效性。
英文摘要
A large-scale microgrid typically consists of several cross-regional subgrids aggregated by a virtual power plant (VPP). However, current consensus based schemes can-not guarantee the feature of differential demand between subgrids. Thus, distributed cluster consensus control induced by communication weights is investigated in this paper to solve the ED problem of a large-scale microgrid, which can achieve the expected cluster via well-designed communication weights. A communication weight matrix design method for a directed and connected graph based on eigenvector centrality is designed, which enables the adjacency matrix of the communication network to have a given leading eigenvector and allows agents in each cluster to have the same eigenvector center value. Based on this, a distributed cluster ED scheme, namely a leader-follower cluster consensus controller, is designed to drive marginal cost (MC) to achieve multiconsensus, thus allocating power among DGs. In addition, the power deficit of each subgrid collected by a VPP can be allocated to utility grids according to predetermined ratios, thus maintaining power supply-demand balance of each subgrid. For this scheme, it should be emphasized that the weighted network used is directed and connected; meanwhile, leader information only can be accessed by a few clusters. Correspondingly, relevant simulations are attached to verify the effectiveness of the designed scheme.
