With the increase of capacity of wind power to the power network
the inluence to the power quality of the network beaomes more and more serious
therefore the the evaluatin and contol of the wind farm power quality to the network is more and mor important. In this paper
a kind of comprehensive power quality evaluation method which combines the ideal weighting method with probability distribution is proposed. The power quality index test value is processed in accordance with the definition of probability distribution. Then
the combined weighting method of AHP and entropy method is used to determine the comprehensive weight of each index. Finally
the power quality of the single wind farm PCC point and wind group are sorted by the ideal solution
and the power quality grade is obtained. AHP
entropy method and abrupt decision method are compared to verify the superiority of the method.
