摘要

Converters can provide reactive power support for the power system and offer advantages such as fast response and flexible control. This paper aims at enhancing power system security by utilizing the reactive power capacity of converters. A voltage security margin index is introduced and an optimization model is developed to improve the voltage security margin index by optimizing the converter control parameters. The effectiveness of the proposed model in enhancing voltage security is validated through case studies on a 39-node system.
