“…Many investigative studies concentrate on optimizing the performance of feeders operating at medium voltages such as 11 kV [1][2][3]. This may be because most of the consumer unavailability occurs at these voltage levels, and because such feeders tend to be similar to one another and can therefore be represented generically.…”

The level of electricity distribution network risk in the UK is perceived to be increasing in the short term, and an asset management approach seeks to optimise the balance between capital expenditure and the risk to customer supplies. Further drivers that could lead to increased network risk can be anticipated in the longer term. Against this background, the paper seeks to model, analyse and quantify both short-term and long-term network risk, and has developed methodologies for doing so. These methodologies are illustrated by a case study based on the anticipated rebuilding of a key 132 kV switching station on part of the UK network.

“…Some years ago a research project was carried out in order to develop reliability based network analysis at the Tampere University of Technology (TUT) in cooperation with utilities and software suppliers [1]. The project resulted in prototype software for reliability analysis as well as a great amount of knowledge about the factors affecting distribution network reliability in general [2,3].…”

Asset management of electricity network is becoming more and more important in the near future due to fact that the need to reinvest in the network is increasing. To manage investments properly, both technical and economical constraints should be considered comprehensively already in the planning phase. In this paper, an integrated networkplanning tool with modern reliability and asset management functionalities is briefly presented. The tool is now integrated as part of the asset management process in Vattenfall. In this paper the utilisation principles of the tool is described. Furthermore, some simplified case studies both in short and long-term network planning is also depicted to shed light on how the tool is used in everyday practice.

“…This kind of study is applicable for completely new medium voltage distribution network as well as for aged existing networks, which should be renovated. In Reference [7] the studies with small fictional network are presented. In the following chapter, study with alternative solutions for real networks is presented.…”

SUMMARYElectric utilities are enforced to control trustworthily total lifetime costs caused by their network components without jeopardizing the reliability and security of the network. New distribution planning methods and procedures are needed in order to meet the expectations and performance targets of regulators, company owners, and customers in the re-regulated environment. One of the most challenging tasks for electrical utilities is the consideration of reliability as a part of long term planning of the network. In order to respond to these requirements, an advanced IT-solution has been created, which provides reliability analysis as a part of the network planning process. The software implementation and the developed models for reliability analysis are presented briefly in the paper. The focus of the proposed paper deals with studies in which alternative network solutions are evaluated using the developed application. For each alternative the total lifetime costs are calculated, including reliability costs. The optimal plan depends on the selection of reliability optimization criteria: the reliability costs may consist only of direct utility costs, but they can also include customer interruption costs and even the costs of voltage dips. The paper presents and evaluates results of example studies and discusses the correlation between the utility strategy and optimal network structure.
