The algorithm underlining the coordination technique is the security-constrained price-based unit commitment (SPUC) which is implemented in two states. At first, GENCOs apply priced-based unit commitment (without transmission security constraints), schedule their generating units and submit their energy and capacity bids to the ISO for maximizing their revenues. The ISO obtains transmission information as well from TRANSCOs via OASIS. Using the two sets of generation and transmission data, the ISO executes inter-zonal and intra-zonal congestion management and contingency analysis for minimizing line flow violations and the risk supplying loads. As part of this package, the ISO would have a chance to minimize both transmission flow and reactive (bus voltage) violations. If transmission flow violations persist after the adjustments are made, the solution would provide a signal to GENCOs, based on Benders decomposition, for modifying their initial bids. Accordingly, additional constraints will be introduced in GENCOs for rescheduling generating units and submitting modified bids to the ISO.","PeriodicalId":127699,"journal":{"name":"LESCOPE'02. 2002 Large Engineering Systems Conference on Power Engineering.

Magnitude is accepted as a significant detection and general classification index in field devices or later assessment analysis. Suitable methods of magnitude characterization are one of the bases of PQD measuring and monitoring. The magnitude of PQD can be determined in several different ways. The RMS voltage, peak voltage and fundamental voltage component are introduced to quantify the voltage severity levels in number of published standards. The paper presents the algorithms of the mentioned approaches implemented in Matlab for quasi real-time situation. The algorithms are FFT-based and/or wavelet transform based. They are validated with the example of the radial test system field voltage sag waveforms provided by the IEEE. The depth-duration characterization of voltage sags is illustrated with the mentioned different approaches. The most appropriate approach is suggested at the end of the paper according to the practical monitoring or measuring requirements. We develop a new PQ monitor with DSP chip infrastructure where all the methods are applied. The proper window length selection and technique to avoid oscillation is also discussed in the rest of the paper. The descriptive information obtained from the magnitude characterization can be used further to extract features for PQD detection and classification.","PeriodicalId":127699,"journal":{"name":"LESCOPE'02. 2002 Large Engineering Systems Conference on Power Engineering.
