Evaluating the coordination between daily curves of probabilistic wind DGs output power and load demand

In this study wind DG units based on various time-dependent load models in radial distribution networks are optimally allocated. For this, while considering Daily Probabilistic output of wind DG units, a multi-objective index (IMO) based on analytical expression is defined. In previous studies, only two indices of real and reactive power losses (ILP and ILQ, respectively) have been considered in IMO, but in this paper, the voltage deviation as an index (IVD) beside other two indices is minimized. In this paper the impact of different optimal power factors of a wind DG (OPFwS) is also evaluated. To reveal the validation of the proposed method, the 33 and 69 bus systems have been examined. Finally, the impression of load models on the wind DG penetration and the coordination level between daily wind DG output and demand curves for each load model are discussed.
