Modelling of Wind/Micro Hydel Turbine driven Induction Generators for Distribution Load Flow Algorithms

Induction generators are very popular in Wind and small scale Hydro based generations which are available in distribution side. For such induction generators, this paper proposes two models which can be used for backward-forward sweep based radial load flow algorithm. The first model is developed using the solution of quadratic equation. In the second model, a methodology has been used which simplifies the induction generator into a two bus system such that the computation got reduced significantly. Using these models, reactive power drawn by the generator and sizing of capacitor to compensate the reactive power is calculated. The methodology is applied to a practical Indian distribution network and the results have been presented.
