摘要
针对微网电能质量问题的复杂性和多样性,提出了基于目标配置的多目标广义比例积分误差校正控制方法的微网SVG电能质量综合控制装置,实现了最优补偿目标确定和最佳容量分配,解决了传统PI控制方法对变化的交流信号跟踪效果欠佳的问题。仿真分析和实验结果表明,所提方法实现了电能质量综合控制装置对微网电能质量问题的多目标复合控制,有效解决微源和各种新型负荷带给微网的多种能质量问题。
Aim at the complexity and diversity of power quality in the micro-grid, the generalized proportional-integral controller based on multi-goal optimization is proposed in this paper, which is applied to the comprehensive control device of power quality to realize the optimal compensation aim and the optimal allocation of compensation capacity. The problem that traditional PI control method is unable to track the ac reference signal is solved as well. The simulation model based on PSCAD and physical test platform are put up to demonstrate the effectiveness of the proposed methods. The simulation and physical results show that the all the issue of the micro-grid power qualities are managed by the comprehensive control device of power quality with the proposed methods. The purpose of all the issue of the micro-grid power qualities are managed by a device only.
