Abstract

Abstract: With the deepening development of UHV AC and DC interconnected power grid, the requirement of power system for voltage and reactive power regulation is becoming higher and higher. As a result, the application of FACTS will hold out a cheerful prospect. However, there is still a lack of effective approaches which are suitable for engineering application and guiding dynamic reactive power compensation. A trajectory-correction sensitivity analytical method is proposed accordingly, which is based on static sensitivity, time domain simulation and trajectory sensitivity, and combines the dynamic analysis and static analysis. The method can reflect the comprehensive effect of dynamic reactive compensation and provide a quantitative index for the optimization of the dynamic reactive power compensation. Through the instance of IEEE39 bus systems and UHV AC and DC interconnected power system, the rationality and validity of the method is verified.

Key words: dynamic reactive, configuration location, UHV, AC and DC interconnected power grid, trajectory-correction sensitivity analysis, static sensitivity, time domain simulation
