基于事件触发的微网分布式经济调度策略

针对传统微网系统分布式控制中通讯负荷重和有功功率经济分配问题,文中提出了一种基于事件触发的有功功率控制策略。各分布式电源在传统一致性算法的基础上采用事件触发方式,有效地减轻了通讯负担。各分布式电源通过事件触发控制器与邻居通信并相互交换有功功率信息,经事件触发控制算法得到最优有功功率值,实现成本最小化下功率经济分配。最后通过MATLAB/Simulink平台搭建微网系统模型,仿真验证了控制策略的有效性。

An Event-based Distributed Economic Scheduling Strategy for Micro-Grid

To solve the problems of heavy communication load and economic distribution of active power in distributed control in the traditional micro-grid system, an event-based active power control strategy is proposed. Based on the traditional consistent algorithm, each distributed power source adoptes the event triggering method, which effectively reduces the communication burden. Each distributed power source communicates with its neighbors through the event trigger controller and exchanges active power information with each other. The optimal active power value is obtained through the event trigger control algorithm, and the economic distribution of power is realized under the minimum cost. Finally, a micro-grid system model is established by MATLAB/Simulink platform, and the simulation experiment verifies the effectiveness of the control strategy.
