Abstract

The harmonic content of supply voltages increases the power consumption of the loads and imposes economical losses on customers. However, the level of economic effects and also the role of power quality instruments for decreasing power losses are unknown. In this paper, an improved model for aggregated loads is proposed. Based on this model, the effects of voltage harmonics on load power consumption and its economical aspects are investigated. The model parameters are identified by practical means, such as capacitor bank switching or load switching methods. The proposed model is verified by comparison of the simulated and measured results. Keywords: voltage havmonics, modeling, parameter identification, power consumption.
