Evaluation of the successive restoration of electricity supply to customers in distribution networks in connection with the regulation of electricity supply continuity

Abstract

The restoration of electricity supply to customers after a failure in the distribution network often represents a complex process consisting of many steps (manipulation) to be undertaken in the network. As a result of this various customers on the same feeder affected by the failure perceive a different number of differently long supply interruptions. This paper deals with the influence of the methodology of evaluating supply interruptions on conventional reliability indices and on the costs of penalty payments. This influence is demonstrated with using real operational data from the overhead network of one distribution company for the period of five years.

“…The level of simplification, however, affects the accuracy of results and the possibility of simulated measures. A view on comparing different approaches to capturing (describing) the process of successive supply restoration, even in connection with data from a control system and evaluation of selected supply continuity indices, was developed in [5]. This study highlights the differences caused by measuring duration of supply interruption only through the outage duration, which is then credited to all affected customers irrespective of the real duration (and also numbers) of interruption suffered.…”
