摘要
微电网容量有限,而系统中越来越多的非线性负载使得系统的电能质量面临巨大挑战.逆变器作为距离非线性负载最近的控制器,对系统的稳定性至关重要.以典型的整流性负载为代表,在传统PI双环控制的基础上,通过理论推导,对微电网逆变器的控制策略进行了改进,通过Matlab/Simulink建模仿真,验证了该策略的有效性.
Abstract
The power quality of micro-grid is faced with a great challenge due to the fact that the capacity of the micro-grid is finite but more and more nonlinear load is used in the system.The inverter is very important to the whole system as the closest controller to nonlinear load.In this paper,a modified control strategy is proposed for the micro-grid inverter with rectifier load, based the traditional double-loop PI control.The results of Matlab/Simulink simulation prove the validity of the proposed strategy.
