A Study of a Damping Control Based Predictive Strategy on an Inter-Area Power System

This paper investigates the predictive control strategy, which is studied for the purpose of stability enhancement of a two area power system with the existance of wind farms and a static synchronous compensator. The model predictive strategy is used to control the active output power of a doubly fed induction generator. On the other hand, the static synchronous compensator is used to compensate for the reactive power output. To reduce the inter-area oscillations, a damping controller is designed and introduced to the system. A linearization technique is utilized to extract the state space matrix of the study system. Simulation studies are carried out using Matlab/ Simulink software. The test results showed that the power output produced from the model predictive controlled wind farms is less vulnerable to fluctuation than power generated from wind farms using the conventional maximum power tracking. Furthermore, the inter-area oscillation of the power system was reduced using predictive control compared to the conventional damping controller.
