Reliability worth assessment of distribution system with large wind farm considering wake effect

The main purpose of this paper is to evaluate the reliability worth of a distribution system with large wind farm. In particular, the wake effect between wind turbines is considered. According to reliability worth indices, the proper wind farm capacity, layout, engineering parameters and connection point with distribution feeders are chosen. Then, main factors that affect the system reliability worth are identified, and the impacts on the whole distribution system are analyzed. The contribution of this paper is the study of wake effect impact on the reliability worth of a distribution system with wind farm. Besides, the effects of wind farm layout, such as spaces between turbines, wind farm rotating angle, and connection point with the distribution system, on system reliability worth are also discussed. A reliability test system RBTS and a wind farm with 18 turbines are used to illustrate the proposed method.
