要約(英語): This paper presents a novel method for monitoring and control of voltage stability of electric power systems. The proposed method is useful for analyzing the voltage profiles under various operating conditions until maximum loadings are reached. A continuation power flow method with predictor and corrector scheme is used to deal with the singularity of the power flow Jacobian, which successfully describe PV curves. The paper also proposes a novel method for optimal voltage regulations using voltage control devices of generators, on-load tap changers, shunt capacitors and reactors. An optimization problem is formulated as MILP problem where the objective is to minimize the control operations subject to operation constraints. Novelty line in the proposed formulation that takes account of possible situations of infeasibility of the control problem, where feasible region disappears and then voltages cannot be regulated within the specified upper and lower bounds. Even in such cases, the proposed formulation works successfully to minimize the total voltage violations exceeding their bounds. It is demonstrated that the proposed method provides successfully the voltage profiles with PV curves as well as the optimal control of the voltage control devices.
