综合提升新能源高占比受端电网小干扰和暂态电压稳定性的SVG优化配置方法
An SVG optimal configuration method for enhancing small disturbance and transient voltage stability in a receiving-end power grid with a high proportion of renewable energy
摘要
Abstract
Because of the weak supportive nature of new energy generation equipment,it is difficult for the voltage support capability of the receiving-end power grid with high penetration of new energy to meet the requirements for system safety and stability.Addressing the inadequacy of existing SVG configuration methods to fully enhance both small disturbance and transient voltage stability,a comprehensive optimization method for SVG configuration considering both aspects is proposed.In the first stage,the total investment and operational costs of SVG and the voltage stability margin during small disturbances of the system are considered.In the second stage,the impact of SVG access on transient voltage stability margin of the system after faults is introduced.Then,the optimal configuration scheme is obtained using an improved ideal solution method based on combination weighting and relative entropy distance.Finally,the PSD-BPA is applied to analyze a case study of a high-penetration new energy receiving-end power grid,validating that the proposed configuration method can effectively enhance the voltage stability of the system through SVG.关键词
