In a competitive market where all producers must participate in the market, WPPs (wind power producers) face two sources of uncertainty: (i) future market prices, and (ii) their production capability in coming hours. In this paper a risk-constrained optimal self-scheduling method for a WPP considering the uncertainty associated with market prices and wind generation is proposed. IGDT (Information...
It has been shown in the literature that partial discharge (PD) pulses can be localized in transformer windings successfully using sectional winding transfer functions. But it is necessary to have the transformer design data to use this method. So the method can not be employed in the cases that transformer design data are not available. Another method for estimating PD location in transformers is...
In this paper an algorithm for PD localization based on using multi-conductor transmission line model is introduced. In this algorithm sectional winding transfer functions are computed using the winding model. To calculate the parameters of the model including resistances, inductances and capacitances between different turns of the winding, it is necessary to have design data of the transformer. Since...
This paper uses detailed model for computation of sectional winding transfer functions that are necessary for partial discharge (PD) localization in transformer windings. In order to increase the accuracy of PD localization in practical cases, the circuit of PD detection impedance is included in the model. Also to increase the reliability, the use of calibration pulses is included in the localization...
