Research on new energy control optimization scheme based on dynamic voltage stability index

Abstract

Abstract This article presents a new energy control parameter optimization method based on the dynamic stability feature. We determine the voltage stability degree of the clean energy access system through the dynamic stability feature and then optimize the control parameters of the clean energy station according to the voltage stability degree of the system. By modifying and optimizing the control parameters of the external loop of the wattless power control, the clean energy has a stronger reactive power support capacity during the low-voltage ride-through period, enhancing the stability of the clean energy access system.
