报告摘要:

Conventionally, the economic dispatch problem for a large-scale power system is solved in a centralized way. In contrast to such kind of approach, a hierarchical decentralized optimization architecture is presented in this talk, by decomposing the centralized problem into decentralized local problems. Each local generator only solves its own problem iteratively, based on its own cost function and generation constraint. An extra coordinator agent is employed to coordinate all the local generator agents. Besides, it also takes responsibility to handle the global demand supply constraint based on a newly proposed concept named virtual agent. In this way, the global demand supply constraint and local generation constraints are handled separately, which would greatly reduce the computational complexity. In addition, as only local individual estimate is exchanged between the local agent and the coordinator agent, communication burden is reduced and information privacy is protected. It is theoretically shown that, based on the proposed architecture, each local generator agent can obtain the optimal solution of the economic dispatch problem. Several case studies implemented on the IEEE 30-bus and the IEEE 118-bus also illustrate and validate the proposed method.
