Event-triggered-based consensus approach for economic dispatch problem in a microgrid
Chao Song, Mei Yu, Wen TAN · Scientia Sinica Informationis · 2018
This study aims to propose an event-trigger consensus approach for the economic dispatch problem (EDP) that is encountered in microgrids. The proposed scheme was based on the consensus algorithm, wherein each agent participated in neighborhood information exchange and local computation. Then, the scheme was converged to an optimal dispatch after iteration. Each agent must sense only its local cost parameters, local load, and neighborhood communication. Furthermore, event-triggered feedback was considered to reduce the frequency of the computation and communication of agents with their neighbors. Communication bandwidth and energy can be saved to meet the goal of the EDP. Several simulation cases were presented to illustrate the effectiveness of the proposed scheme.
