“…PHC: (13) UPF: (14) Equation (12)- (14) show that the resulting compensated currents from all strategies with very different performances have a similar structure. They can be represented by the product of a scalar, and a vector which is a function of voltages.…”

This paper gives a new insight into the concept of load compensation under distorted voltages. Achieving both unity power factor (UPF) and perfect compensation of current harmonics are not possible where a competition will arise between these two important factors. Through evaluating the present control strategies, a generalized, optimal, and flexible control strategy (OFC) for harmonic compensation of utility lines is proposed. The proposed control strategy, which provides a unified and highly flexible compensation framework has the ability of programming for perfect current harmonics compensation, or (UPF) accomplishment, or other newly defined objectives such as maximizing the power-factor subject to some adjustable constraints on the level of current harmonics and unbalancing via an on-line optimization algorithm. The strategy can fulfill the IEEE-519 standards requirements, while guaranteeing the best achievable power factor and optimum required rating for the compensator. Theoretical concepts and practical features of the proposed control strategy have been shown through extensive simulation studies using MATLAB/SIMULINK programs.

“…UCR and LCI are complementary, using the same procedures to be calculated, and the results presented by both are concordant with other indices published and improved in the case of the capacitors presence. Thus, the experimental values of the used indices will be compared with the HGI, [10], the SRI, [21], and the DAQ, [20], to verify their performance and to prove the better results in the presence of capacitors.…”

“…Finally, there is another set of methods in the literature based on the current decomposition, [9,20,21,28]; among them, the NonColinear Index (NCI), [21], and the Non-Linear Index (NLI), [20], these will be used in the experimental results assessment in this paper. Another of those methods is the Load Characterization Index (LCI), [9], proposed by Herrera and Salmerón, which is based on the decomposition of current at the input of the load into two components: a current component which introduces harmonic distortion into the system and a second current component which does not introduce harmonic distortion, and whose harmonic distortion is the same as that of the voltage.…”

A method has been presented for the allocation of responsibilities between a utility and a consumer with reference to the distortion of 3-phase voltage waveforms at the point of common coupling. The input data required for applying this method are the measured voltage and current waveforms at the point of common coupling. The frequencies in the measured waveforms are estimated and a Kalman filter is used to estimate the phasors at these frequencies. Subsequently, the parameters of the electrical system of the industrial load have been estimated using the recursive least-squares technique. With these estimated data, the individual contributions to the distortion of the 3-phase voltage waveforms have been calculated. The proposed method has been illustrated by means ofa practical example.
