摘要
针对微网输电线路中阻抗不同影响分布式电源(DG)的输出电压问题,在微网分层控制中引入一致性算法和事件触发控制。将各DG的输出电压偏差值进行触发等级划分,根据不同的电压偏差等级触发不同的电压补偿方式。针对各DG之间通信延时问题,对一致性算法进行优化。在MATLAB/SIMULINK仿真平台对事件触发电压补偿及改进延时一致性算法的有效性进行验证。
Aiming at the problem that output voltage of the distributed generator(DG)is affected by different impedance in microgrid electric transmission line,consistency algorithms and event-triggering control are introduced to the hierarchical control of the microgrid.The trigger condition is divided according to the output voltage deviation value of DG,and different voltage compensation modes are triggered by different voltage deviation levels.The consistency algorithm is optimized for the communication delay among different DGs.The effectiveness of the event trigger voltage compensation and the improved delay consistency algorithm is verified on the MATLAB/SIMULINK simulation platform.
