Suppression for Transient Voltage in Renewable Micro-grid by Power-Synchronous-Reactive-Compensation

This proposed a transient voltage suppression method for renewable micro-grid based on power-synchronous-reactive-compensation (PS-RC). Firstly, the main circuit and control system of PS-RC is introduced. Then, with the case study presented in this paper, the function of PS-RC in suppression of transient voltage with a time-domain simulation is validated, which is analyzed from the perspective of voltage stiffness. Moreover, the disturbance in micro-grid is divided into grid-connection and off-grid.
