摘要:
In this paper, an uncertain economic dispatch problem (EDP) is considered for a group of coopertive agents. First, let each agent extract a set of samples (scenarios) from the uncertain set, and then a scenario EDP is obtained using these scenarios. Based on the scenario theory, a prior certification is provided to evaluate the probabilistic feasibility of the scenario solution for uncertain EDP. To facilitate the computational task, a distributed solution strategy is proposed by the alternating direction method of multipliers (ADMM) and a finite-time consensus strategy. Moreover, the distributed strategy can solve the scenario problem over a weight-balanced directed graph. Finally, the proposed solution strategy is applied to an EDP for a power system involving wind power plants.
