Investigating the Electrical Integration of Wind Power Based Embedded Generation into Utilities' Networks

摘要

Recently wind power based embedded generation (WPBEG) has received considerable attention world-wide. Generators of such power plants are usually connected to utilities' electrical networks at distribution levels. Previous experience has shown that the integration of such generators into utilities' distribution networks (DNs) could create safety as well as tecnical problems. Such problems include contribution to the fault currents, stability, voltage fluctuation, and problems to the automatic voltage control, etc. Therefore, the operation of DNs that include WPBEG requires investigation both during steady state and dynamic conditions. This paper reports an investigation conducted on a simulated system consisting of a windfarm integrated into a DN using Alternative Transient Program (ATP). The investigation covers two main aspects; the effect of the integration of the wind farm into a DN on the settings of protective relays of electrical feeders and its effect on the power quality of the electrical supply. Results obtained from various simulated case studies are presented and discussed.
