Solutions from a national Smart grids demonstration site exploring a fiber-optic communication infrastructure
The paper presents general background and drivers for the development of Smart grids technologies in Norway, with emphasis on the need for and status on developing national demonstration sites for technology testing and validation. The paper further presents the demonstration site which is being dev...
Regulation of quality of supply - an innovation driving force? Novel equipment for reducing customers' interruption costs by bypassing switches during maintenance
The paper deals with localization of phase-to-phase shortcircuits on a medium voltage (MV) feeder with distributed generation (DG). Fundamental frequency currents and voltages are utilized for estimating the distance to the fault location. Loads and DG connected to the feeder cause errors in the est...
General framework for maintenance management
This report outlines a general framework for maintenance management of distribution systems assets. The maintenance management process proposed covers both the maintenance activities as well as the triggering conditions for reinvestment analysis. The importance and use of risk assessment in maintena...
Incorporating short interruptions and time dependency of interruption costs in continuity of supply regulation
Customer costs related to interruptions and voltage problems: Methodology and results
This paper presents the methodology and main results of the most recent Norwegian customer survey on consumer valuation of interruptions and voltage problems. The survey provided cost estimates that have been incorporated in the quality of supply regulation, in terms of the cost of energy not suppli...
Trends in quality of supply in a liberalized electricity market
Trends in Quality of Supply in A Liberalized Electricity Market
It is a question of concern if - and how - the vulnerability of the electric power grid and probability of interruptions is increasing as assets are ageing and components are being utilized closer to their limits. These aspects may have severe long-term consequences which it is of vital importance t...
Interruption Costs and Consumer Valuation of Reliability of Service in a Liberalised Power Market
This paper addresses the methodological issues related to data normalization and the estimation of customer average interruption costs that are suitable for incorporation into performance-based regulation regimes. The paper describes methods and algorithms developed to calculate individual and secto...
