Effects of operational modes of distributed wind generators on distribution networks

This paper investigates the impacts of a wind generator's control mode on voltage profile, power loss, and transient stability of a distribution system. A doubly fed induction generator (DFIG) type wind turbine is operated in its different modes (power factor or voltage control) to investigate their influence on a nearby combined heat and power (CHP) plant based on a synchronous generator. Simulation results indicate that although the integration of a wind turbine in a distribution network improves voltage profile and power loss, operational modes of a DFIG and nearby synchronous generator control may interact negatively which could lead to a reduction in damping of the system.
