TLDR
In this paper, the authors proposed an approach to quantifying the distortion caused by a single customer, when there are many customers in the network, by isolating the contributions to waveform distortion from a customer side and the supply side.Abstract:
In this paper, we propose an approach to quantifying the distortion caused by a single customer, when there are many customers in the network. We have described a method for isolating the contributions to waveform distortion from a customer side and the supply side. The voltage and current measurements at a single point are sufficient. This approach will be useful in arriving at equitable ways of settling customer complaints, sharing the cost of waveform distortion through rate structures, penalties, etc. The principle is illustrated using six example loads. The method proposed can be implemented in any power quality measurement device, which monitors the voltage as well as the current harmonics simultaneously.read more

A control algorithm for compensation of customer-generated harmonics and reactive power
TL;DR: In this paper, a new control algorithm for a shunt active power filter to compensate harmonics and reactive power required by nonlinear loads is presented, which provides an additional feature of compensation of either only harmonics, or both harmonics or both reactive power simultaneously, based on the desired capacity of the APF.

Survey of harmonic levels on the Southwestern Electric Power Company system
TL;DR: A survey of current and voltage distortion levels measured at 76 different sites is presented in this paper, where the authors use data at a particular nonlinear load site to show how US utilities may be failing to collect the correct revenues from power factor penalty clauses.
