With the development of modern electricity equipment, voltage dips may bring more and more economic losses, which need a proper method of evaluation. In this paper, a time varying quality loss function, utilizing the Tobit model, is used to predict economic losses due to voltage dips. This quality loss function is more flexible and closer to practical situation.
In recent years, consumers of power energy pay more and more attentions on power supply quality, they demand high level supply quality. Therefore, the cost of power quality becomes a main issue to utility engineers when they consider power quality problems. For many industry customers, the main components of power quality costs are short interruption, voltage dips and harmonic costs. The data used...
