A framework of security-constrained adequacy evaluation (SCAE) based on analytical techniques is proposed to assess the ability of a bulk power system to supply electric load while satisfying security constraints. It encompasses three main steps: (a) critical contingency selection, (b) effects analysis, and (c) reliability index computation. Effects(More)
This paper provides a methodology to characterize the accuracy of PMU data (GPS-synchronized) and the applicability of this data for monitoring system stability via visualization methods. GPS-synchronized equipment (PMUs) is in general higher precision equipment as compared to typical SCADA systems. Conceptually, PMU data are time tagged with precision(More)
– A comprehensive model for stochastic load flow analysis in electric power systems is proposed for the purpose of estimating the statistics of bus voltage magnitudes , circuit currents and transmission line power flows. The proposed method is driven by a realistic non-conforming stochastic electric load model, defined in terms of few independent stochastic(More)
