An MPC strategy for automatic generation control with consideration of deterministic power imbalances

This paper presents a Model Predictive Control (MPC) approach for Automatic Generation Control, suitable for tackling deterministic frequency deviations in a multi-area interconnected power system. The current Proportional-Integral (PI) controllers were compared to the implementation of MPC in a single area and also in all areas of an interconnected system. In a direct comparison, the MPC-based frequency control proved to be superior to the traditional PI control scheme. Moreover, the effect of inaccuracies between the MPC model and the dynamic model of the power system was studied. The proposed controller was found to be robust against inaccuracies of the model and possible external disturbances.
