Nodes in electric distribution networks are greatly differentiated and are very often nonlinear
and/or unbalanced. They can create significant harmonic pollution, with harmonics that …

Throughout the last years, with the liberalization of the energy market, the localization of the
sources of power quality disturbances has become a nodal point for operators and …

As the ratio of nonlinear loads fed from grids are increasing day by day, harmonic pollution
problems seem to be more and more serious. Problems related to harmonics are the main …

A measurement system, based on high-performance Global Positioning System (GPS)
receivers and general-purpose acquisition (DAQ) boards, for the evaluation of the …

This article investigates the feasibility of using a simplified approach, based on the
measurement of power ratio parameters, for harmonic emissions assessment at the point of …

A number of proposals have been made to account the different sources of harmonics in
power system and relate it to a harmonics‐based revenue structure. Any suggested method …

In power systems, knowledge of system state is required to operate management and
control issues, such as energy dispatching and protection coordination. The authors have …

In a liberalized electric market, the knowledge of the system status is required to deal with
management and control issues, such as energy dispatching and protection coordination. In …

The harmonic active power is used to determine the location of polluting loads, the direction
of harmonic power flow and to estimate how consequential a certain current harmonic …

In modern power networks, the issue of power quality (PQ) is becoming very important
because of the increasing of load which sensitive to current disturbances. This is mainly due …
