Lookahead Control based framework for power system applications

Robustness of the power system can be enhanced with appropriate autonomic control action following the disturbances. Predictive optimal tuning of real time control parameters from the finite set of control actions is considered in this paper to prevent from impending system deterioration. We present the formulation of generic, higher layer model based Limited Lookahead Control (LLC) approach that can be applied to variety of power system applications. System model including the lower level controller , load dynamics and network is used to assist the controller action. Discrete time control decisions are made based on the optimization of the predicted response to a limited horizon from the developed model. Finally, we present a case study to demonstrate the applicability of the proposed framework. Nine bus multi-machine power system benchmark is considered for voltage control with the finite set of capacitor tuning.
