摘要

This paper presents a comprehensive approach to evaluate the effects of voltage and reactive power control methods for local and coordinated control schemes applied to wind generators (WGs) in distribution networks. Considering uncertainties related to variation of load demand, wind speed and outage of WGs, the approach employs a Monte Carlo-based framework to ascertain the benefits and drawbacks of each scheme with respect to the resulting statistical attributes of voltage profiles, tap activity of on-load tap changers and total active power losses. A 20 kV radial distribution network with four identical feeders, which resembles a typical case in Germany, is used for numerical tests.
