Abstract

The present work describes a novel control strategy applicable to power electronic converters intending to provide ancillary services to the electrical power grid in terms of power factor compensation. This objective is achieved through a nonlinear control strategy centered on nested control loops based on super-twisting sliding modes and nonlinear optimal tracking control. To make the power converter output track a desired reference current to inject the required reactive power for the power factor compensation at a power system node. Simulation results demonstrate the effectiveness of the proposed control scheme by guaranteeing unitary power factor regulation in the face of abrupt load variations.
基于电力电子变换器最优控制的动态功率因数校正
本文描述了一种适用于电力电子变流器的新型控制策略,旨在为电网提供功率因数补偿方面的辅助服务。这一目标是通过基于超扭转滑模和非线性最优跟踪控制的以嵌套控制环为中心的非线性控制策略实现的。使功率变换器输出跟踪所需的参考电流,以在电力系统节点注入功率因数补偿所需的无功功率。仿真结果验证了该控制方案的有效性,保证了系统在负荷突变情况下的功率因数稳定。
