dcterms.abstractThis paper presents a novel model for optimal coordinated voltage emergency control (OCVEC). It takes account of the dynamics of loads and discrete/continuous nature of controls with coordination of dissimilar controls at different geographical locations in order to keep the desired voltage profiles against voltage collapse during an emergency. An integration index of the bus voltage deviation is adopted as the voltage stability performance index. The sensitivities of this performance index with respect to controls are derived using the optimal control theory. Since the sensitivities can be evaluated using the fast quasi-steady-state time domain simulation results, the intractable OCVEC model can be transformed into a tractable problem of quadratic programming. The effectiveness of the proposed model and its solution strategy is validated by case studies on the New England 39-bus and Nordic 32 power systems.-
