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 to the increasing use of non-linear power electronic devices draws non-sinusoidal current and creating a current distortion. As a result there is increasing need for PQ to be monitored to establish the type, sources and locations...
The present article extends a previous work where a state estimation technique was applied to a power distribution system to determine the amplitudes and phase angles of the harmonic currents injected at its buses. The nodal harmonic voltage amplitudes and phase angles were presented as the state variables and the corresponding current parameters were then obtained indirectly through calculation from...
Due to an increase of power-electronic equipment installation and other harmonic sources, the identification and estimation of harmonic loads are of concern in electric power transmission and distribution systems. Conventional harmonic state estimation requires a redundant number of expensive harmonic measurements. In this paper, we explore the use of a statistical signal-processing technique, known...
