Abstract [en]

Power systems are becoming older and more intense. Thus, disturbances are inevitable and it is important to develop a powerful methodology to lessen the damages afterward. This paper proposes a new linear formulation based on an approximated version of AC power flow model to compromise between speed and accuracy of decision making process. In the proposed method, voltage and reactive power violations as well as transmission system overloads are alleviated by either or both of generation rescheduling and load shedding. The developed method adopts the line flows and square of voltage magnitudes as the problem state variables. Simulation results on the IEEE-RTS96 system reveal that the proposed method outperforms both the conventional and heuristic approaches from the execution time and the computational effort viewpoints while keeping the accuracy of the results.
