Assessment of flicker impact of fluctuating loads prior to connection

With the acceptance of IEEE Std. 1453, many utility companies in North America are facing problems in applying the recommended concepts. These problems center around difficulties in predicting flicker produced by specific customers or loads before they are connected. The discussions in this paper are intended to serve as an overview of some of the methods that are commonly used, mostly outside North America, to perform pre-connection flicker assessments of fluctuating loads.
