Abstract
This paper presents a methodology that allows performing the optimized and coordinated management of reactive power injection in power systems with wind farms and other sources of reactive injection, such as capacitor banks or static voltage compensators, minimizing the losses in the transmission power system. The variation in wind speed is characterized by the Weibull distribution. The values of this distribution are used as input data for the optimal power flow model whose output provides a sample of values for defining the confidence intervals of the injected reactive power, as well as the voltage values in each bus of the electrical system. The proposed methodology was tested using a real 140 buses system to determine the dispatch of reactive sources available in the power system. The results found by the proposal can help to make a better management of the available reactive sources in the real-time operation.
