A novel methodology for measurement-based low-voltage loss estimation

Abstract

This paper presents a unified loss theory, a measurement and computation method for the determination of network losses. This approach enables to jointly treat and compare the different components of losses such as reactive current, time-variance, asymmetry and harmonic currents, thus making it possible to evaluate the effect of different loss-reduction investments. Further a stochastic loss computation method is introduced, and compared to the previously shown method. Finally, measurement results and their evaluation are presented.
