Comparison Analysis of Virtual Inertia Control Methods for Smoothing Power Production of Grid Connected Wind Farm on a Power System

This paper presents comparative study of Virtual Inertia Control System (VICS) techniques for smoothing power production of enormous wind farm which connected to the electric grid system. Four commonly used VICS methods, synchronous generator model-based, swing equation based, droop-based approach, and frequency-power response-based, are compared in terms of effectiveness in smoothing wind farm power production and damping frequency fluctuation of the power system. The VICS is applied on the inverter based STATCOM/BESS which connected to 9-Bus power system model. The PSCAD/EMTDC has been used to perform the simulation analyses. The simulation study demonstrates that the frequency-power response-based VICS is superior for minimizing power fluctuation from the wind farm.
