Wind Speed Variation Impact on Transmission Loss Reduction in Electricity Market

In this paper, effect of wind speed variation on its output has been obtained and analysis has been carried out for transmission loss minimization. Mixed integer nonlinear programming (MINLP) approach has been utilized for determining optimal location and number of DFIG as distributed generators considering minimization of transmission loss. The impact of wind speed variation has also been incorporated in the optimization model for obtaining the impact of DFIG output on the transmission loss. The capability curves of DFIG have been modeled in an optimization model and impact of wind speed variation for 24 hrs has been considered to obtain the impact on DFIG output and thereby on the transmission loss. The total real and reactive power loss, optimal DG location, 24 hr optimal schedule of conventional generators and DG output has been obtained. The effect wind variation is determined on the location and output of DG. The proposed MINLP based optimization approach has been applied for IEEE 24 bus reliability test system.
