Conception of low voltage network loss reduction based on integrated information

Abstract

Significance of business and technical information system integration in distribution utility using geographical information system (GIS) is presented in this paper. Motives for GIS base creation are depicted as basis for network operation improvement and loss reduction. Improvements of software for network planning and analysis that include GIS elements are described, specially those related to future loss reduction application. Conception of loss reduction based of collected GIS and energy data in Serbian distribution networks is presented. Presentation is gradual: from the most detailed data set to the least detailed but necessary data set collected in distribution utilities.

Multi-criteria assessment of the smart grid efficiency using the fuzzy analytic hierarchy process

“…In this paper fuzzification is implemented by triangular fuzzy numbers, and the value of fuzzy distance of 2 is used; on boundaries, (1,1,3) is used for 1, and (7,9,9) is used for 9. It is used a fuzzy distance of 2 for odds (3,5,7), and a fuzzy distance of 1 for pairs (2,4,6,8), as recommended in [33], because the most consistent results can be expected.…”

“…A smart grid is usually defined as an electrical grid that intelligently integrates the actions of all users connected within itproducers, consumers, and those who are both, with the purpose of efficiently producing electricity and delivering it sustainably, economically, and safely [1]. The smart grid promises a variety of efficiency gains for utilities, like the reducing distribution line losses through minimization of reactive power and more precise voltage control [2]. Furthermore, the smart grid should enhance utilities" ability to monitor and measure the effectiveness of end-use energy-efficiency programs, and to better manage energy costs on the customer side, which is confirmed by the numerous projects and organizations that were initiated to facilitate the evolution of the Smart Grid [3], [4].…”
