Load frequency control and tie-line damping via virtual synchronous generator

Abstract This paper proposes the participation of the virtual inertia of wind generation in the control of load frequency and damping of oscillations in interconnection lines. The proposed approach considers high penetration of Wind Farm Power Plant (WFPP) connected to hydro generation area. Virtual wind inertia has been widely investigated to control frequency in an interconnected system. As the WFPP is usually connected to the grid through static converters, they can act quickly to provide the Load Frequency Control (LFC) with fast dynamics. Therefore, the main idea is to include an additional fast control action with the objective of aiding the frequency stabilization to damp oscillations in interchange power line. It seeks to reduce the inverse response of hydro power plant and maintain a scheduled wind power. A hydro-wind power system is used to show the effectiveness of the proposed approach.
