“…The simplest current source method uses the sequence component framework by injecting ideal current sources into the power network [8]. In a later contribution, the solution is directly obtained in the phase domain for three-phase unbalanced systems [9].…”

This paper presents a review with a concise description and analysis of the fundamentals, characteristics, analytical details, merits, and drawbacks associated with existing methods in frequency and time domain for harmonic analysis in practical power networks. The description and analysis are centered on methods developed in the harmonic domain, hybrid frequency-time domain, and time domain, respectively. Validation of the reviewed methods for harmonic analysis, against one of the widely accepted digital simulators, such as EMTP, EMTDC, or MATLAB/SIMULINK, is reported in the cited individual contributions.

“…This procedure may be Newton-Raphson-based technique [47][48][49][50] or a technique based on the injection current response of the network [49,50]. In each of these methods, the signal level at harmonic sources must be known, estimated or calculated.…”

SUMMARYThe increased use of power electronic controlled equipment, such as variable speed drives, automated production lines, personal computers and non-linear electronic devices in power systems has given rise to a type of voltage and current waveform distortion called as 'harmonics'. Harmonic can be defined as the undesirable components of a distorted periodic waveform whose frequencies are the integer multiples (non-integer multiples in case of inter-harmonics, and the frequency less than fundamental frequency in case of sub-harmonics) of the fundamental frequency. Presence of these harmonics results in increased losses, equipment heating and loss-of-life, and interference with protection, control and communication circuits as well as customer loads. The research has been underway since very beginning for control of power system harmonics and to supply consumers with reliable and 'clean' fundamental-frequency sinusoidal electric power that does not represent a damaging threat to their equipment. This paper, therefore, reviews the progress made in power system harmonics research and development since its inception. Attempts are also made to highlight the current and future issues involved in the development of quality and reliable electric power technology for future applications. A list of 145 research publications on the subject is also appended for a quick reference.

“…Due to its simplicity, one of the methods of greater acceptance for harmonic propagation studies is the current injection method which was introduced at the beginning of the 1980s by Pileggi et al [1] and by Mahmoud and Shultz [2]; and then diffused in literature by Densem et al [3] and by Acha and Madrigal [4], just to mention a few. Broadly, this method consists of the following processes.…”

“…However, although this method arose precisely in distribution systems (see Pileggi et al [1] and Mahmoud and Shultz [2]), nowadays it is more frequently used in transmission networks, where the process 1 is solved in most cases by using Newton-Raphson method or its decoupled version; the process 2, admittance calculation for linear loads, is solved by means of the nodal voltages of the previous process and one suitable model that represents the nature of the load for which some model of CIGRE Working Group 36-05 [5] can be used. The last process, harmonic voltage calculation, is easily achieved if one dispose of the admittance matrix, whose preparation is dependent on the previous two steps, and the nodal current vector, both given in eq.…”

This work presents a method for calculating harmonic voltages and currents in radial distribution networks. The proposed method is an extension of the backward/forward sweep method for load flow studies in distribution systems and as such preserves its good convergence characteristics besides of not requiring of any network matrix. The method was tested on an eight-node one-phase radial test feeder and results were similar to those that were obtained by the well-known current injection method. Also it was tested on a 2000-node network, showing this way that this is a more suitable method for large three-phase radial distribution networks.
