摘要

本文通过孤岛结构的选择,讨论了微电网中电压和频率的控制问题。所提出的控制方案被用作前馈补偿策略,以减少非线性效应并补偿负载的动态。在此基础上,引入了分布式电源系统的数学孤岛模型,设计了电压和频率控制器,实现了快速稳定的响应和零稳态误差。通过Matlab-Simulink软件对系统在不同负载条件下的运行情况进行了校核。仿真结果表明,设计的控制器构成的闭环系统具有鲁棒性。

Advanced feed-forward strategy to dynamic control of the islanded micro grids
In this paper, by choosing the islanded structure for DER, the problem of voltage and frequency control in micro grids is discussed. The proposed control scheme has been used as a feed forward compensation strategy to reduce the nonlinear effects and to compensate for the load dynamics. Thus, the mathematical islanded model of DER system has been introduced and then, the voltage and frequency controllers have been designed to achieve fast and stable response and also zero steady state error. The operation of system in different load conditions is checked by Matlab-Simulink software. The simulation results show the robust operation of closed loop system composed with designed controller.
