The Fuzzy Approach to Energy Losses Calculations in Low Voltage Distribution Networks

Abstract

The occurrence of electric energy losses is connected with the energy production, transmission and distribution processes. The proper computing of electric energy losses is one of the most complex problems in power distribution system analysis, demanding consideration of many factors. The accessibility and credibility of data used in calculations is of the greatest importance here. The careful analysis of system losses is desirable in this respect. "Tis article presents the mathematical model of electric energy losses in low voltage networks with application of fuzzy sets theory. Usage a fuzzy approach makes possible to improve loss calculations accuracy. Theoretical statement is illustrated by an example which corresponds to Polish distribution system.
