The impact of voltage dips on industrial installations can be very high. However, regulation within the European Standard EN 50160 is not detailed as the cells within the general table are not filled. As there is no reference on the expected number of voltage dips, the responsibilities for network operator and customer are unclear. Therefore the customers face challenges to make analysis on required mitigation measures. The Dutch Regulator requested the network operators to prepare a proposal for a regulatory framework regarding voltage dips. This paper presents the initial proposal for the MV distribution network. Based on the effect of various types of voltage dips to the reduction of active-power for aggregated customers, voltage dip severity weighting factors are developed and used to build the proposal
