Reasonable maintenance strategy can decrease power grid operation costs and enhance competitiveness of power grid. Therefore, according to the principle of system condition-based maintenance, an equipment imperfect maintenance model is built based on a modified Kijima II model, which considers electrical equipments' maintenance outage model and repair outage model and the effects of equipment maintenance...
The purpose of this paper is to formulate, document and present a novel optimal distribution substation bus design methodology considering reliability and economics. A simple test system is used to evaluate and compare four common distribution substation bus configurations. Capital, maintenance and operating costs including the costs of system losses as well as the expected customer outage costs have...
Traditionally, reliability evaluations for substation configurations and distribution networks are performed separately and substation reliability evaluation only focuses on a single substation. This paper presents a technique to assess the reliability of multiple substations with associated distribution networks. Based on Markov modeling, a clustering approach, a linear programming algorithm and...
The paper discusses the modeling of substations for reliability, dealing with each equipment and its influence in the topology. The study consider the power availability for each load, using either an analytic and a simulation model. Some results and a software implementation are presented.
One of the most important purposes of reliability assessment of distribution network is reducing interruptions for customer service. In this paper reliability of large distribution network of a city is calculated based on probabilistic method. After analysis the reliability indexes, some solutions are introduced to improve weak zones. By comparing results and using simple approaches we can improve...
