A load flow algorithm for practical distribution systems comprising wind generators

The power world is ambling towards eco-friendly distributed generation (DG), their integration into the distribution network poses challenges to existing load flow techniques. As wind energy is used as a DG power source, its impact on the distribution system needs to be analyzed. This requires a load flow algorithm capable of simulating both radial and weakly mesh systems along with Wind Turbine Generating Units (WTGUs). The compensation based distribution load flow algorithm is extended including WTGU modeling in the present work. The algorithm is used to study the system behavior with respect to losses and voltage profile with varying wind speeds. The algorithm may easily be extended to a generalized/practical distribution system for the selection of WTGU location.
