An H2 preview control method is applied to Load Frequency Control (LFC) and the control performance improved by the prediction of load variation is examined based on numerical examples. The performance of the preview control is measured by the power system inertia constants, which are required for recovering the same control performances with the standard H2 control. We report that the use of load demand prediction has a good effect on recovering the power system inertia constants.
