Damping Improvement of Inter-Area Oscillations Using Large-Scale Wind Farms

Abstract

This paper investigates the ability of large scale wind farms in damping improvement of inter area oscillations in power systems. Considering the increasing penetration level of wind farms in power systems, their contribution in damping improvement of oscillations will be of great importance. The purpose of this paper is to employ the synchronverter control model for wind farms in order to enhance the inter area oscillations. To perform required simulations, the wind farm as well as its controllers are thoroughly modeled in DIgSILENT Power Factory using DSL programming. The Kundur two-area test system is utilized for time domain simulations to demonstrate the capability of wind farms with synchronverter control models in damping improvement of inter area oscillations. Simulation results reveal the suitable performance of the investigated method in the event of various disturbances including short circuit faults and mechanical torque variations of synchronous generators.
