Abstract

Abstract: ABSTRACT： A smart substation, which represents the development trend of advanced substation technology, is an important part of a smart grid. The configuration of smart substation could have significant impacts on the secure and economic operation of the distribution system concerned, and is an important problem to be addressed. Given this background, this paper studies the intelligent upgrading strategy of substations in power distribution system with reliability indices considered. First, we construct the intelligent upgrading optimization model of substations in power distribution system to minimize the upgrade costs of existing conventional substations and the interruption costs of customers, with considering the constraint conditions that two reliability indices including the system average interruption duration index （SAIDI） and average energy not supplied （AENS） dont exceed a given threshold. Secondly, we present a fault clearing model for power distribution system and propose an accurate assessment method for the users outage time. Then, we linearize the users outage time and outage cost function to obtain a mixed integer linear programming model for the intelligent upgrading strategy of substations, which is solved by efficient commercial solvers. Finally, the IEEE RBTS-Bus 4 distribution power system and an actual medium voltage distribution network in Denmark are served for demonstrating the basic characteristics of the presented method.

Key words: distribution system, smart substation, reliability, outage time assessment, mixed integer linear programming
