Abstract
With three test systems, the paper demonstrates the ability of system-wide harmonic state estimation (HSE) to identify remote harmonic sources and estimate load admittance of a power system, from a few synchronised, partial and asymmetric measurements. Implemented offline or online, it turns multipoint measurements to system-wide measurements in a very economical way. System-wide HSE provides an efficient power quality tool for assessing the impact of hidden harmonic sources on the overall performance of power systems
