Abstract

Abstract:

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.

Key words: micro-grid, consistency, event triggering, distributed, communication, economic dispatch
