1Emergency alleviation of thermal overloads using model predictive control

Abstract—An approach inspired of Model Predictive Control is proposed to determine a sequence of control actions aimed at alleviating thermal overloads in emergency conditions. The algorithm brings the line currents below their limits in the time interval left by protections, while accounting for constraints on control changes at each step. Its closed-loop nature allows to compensate for measurement noise and model uncertainties. Index Terms—Thermal overload, emergency control, model predictive control, constrained optimization I
