Abstract

In this paper, an angular frequency dynamic-based control technique is proposed to control interfaced converters between the power grid and renewable energy sources. The proposed control technique can guarantee a stable operation of power grid under high penetration of renewable energy resources through providing the required inertia properties. The synchronous generator characteristics combined with the basic dynamic model of the interfaced converter can shape a second order derivative of the grid angular frequency consisted of converter power and virtual mechanical power derivative with embedded virtual inertia to prevent from the power grid instability as well as generate active and reactive power with appropriate inertia. Simulation analyses are performed in Matlab/Simulink to confirm high performance of the proposed control technique.
