With the development of technologies, demand for good quality electric power is increasing day by day. In Distributed Generation Systems (DGs), can cause serious problems such as sensitive equipment's malfunction, temperature riseof machines. Therefore, detection events in system more important to take further actions. The existing classification methods have high computational time with low ac...

In this paper, the main Power Quality (PQ) problems are presented with their associated causes and consequences. The economic impacts associated with PQ are characterized. Finally, some solutions to mitigate the PQ problems are presented.

This paper describes two hardware prototypes and estimation schemes for determining the parameters of a simple, physically based, point-of-use electric utility model using transient measurements. Parameters of the utility model are estimated using data collected by the prototypes. Frequency-dependent effects observed in previous work in this area are modeled. Performance of the techniques given...
