“…A newly developed was introduced using the voltage -current ratio for harmonic source detection at the PCC [10]. This method requires the measured voltage and current at the PCC as well as the utility and custome's equivalent impedance values.…”

“…This method requires the measured voltage and current at the PCC as well as the utility and custome's equivalent impedance values. Reference [10] concluded that this does not only detect the harmonic source, but it also determines the contribution between the parties. Reference [28] developed a current-voltage ratio for harmonic current source detection.…”

“…The amount of harmonic distortion present at the PCC is subjected to the installation of a customer and the background harmonic as part of the utility side [9]. The background voltage distortion can no longer ignored or assumed to be minimal, as in some cases, it caused high harmonic currents at the PCC [10]. Currently, there are no guidelines that is limiting the background harmonic, it becomes a need for the National Regulator to develop a guideline to lead power quality engineers during the planning processes.…”

“…The location of harmonic source detection has been part of research since the 1990's [11] as the non-linear loads became part of the power system. Many methods and techniques have been developed and reported in the literature to detect harmonic source [8], [9], [19]- [26], [10], [12]- [18]. These methods and techniques have been in discussion and scrutinise on certain issues.…”

Ensuring the quality of power supply is a main target of the power utility companies worldwide. Harmonic distortion is one of the power quality problems that can result either from upstream (utility side) through background harmonic, downstream (customer's side) through non-linear loads, or renewable energy generators. The detection of harmonic sources at the point of common coupling (PCC) is a major concern for both utilities and customers. Various methods have been proposed since the 1990s to be used for harmonic source detection. These methods have been classified into three categories based on the direction of active power flow, reactive power, and voltage-current ratio. In this paper, a systematic literature review is done on the state of the art of current research on the harmonic source detection methods, in order to select the method that gives better practical and commercial results to be used when multiple customers are connected at the PCC. This systematic literature review recognized that most studies concentrated only on harmonic source detection between a customer and utility but the practical power system has multiple customers connected to the PCC with different load conditions. Therefore, the results obtained from this paper review will be useful for researchers and engineers working in the modern grids, who aim to develop a practical and commercial method to quantify the harmonic contribution for different customers and utility.INDEX TERMS Harmonic distortion, harmonic source detection, renewable energy sources and distributed power generation.

“…However, a variety of studies have shown that the current source models are not sufficiently accurate. For instance, most recent evaluation methods [3–5] have been developed based on the Norton or Thévenin equivalent circuits. In [6, 7], it has been demonstrated that the new methods with such detailed models result in a better evaluation of the harmonic behaviour.…”

This study addresses the validation of harmonic models for power generation units considering practical aspects associated with test-bench and on-site measurements. A new method is proposed for the harmonic model validation. This method has been developed within the joint research project 'NetzHarmonie,' which deals with the study of harmonic emissions of renewable energy sources in the power system. The main idea for model validation is to compare the harmonic voltagecurrent characteristic of the model with the measured harmonic voltage-current pairs. This idea is implemented in a practical process by considering measurement uncertainties as well as the time variation of harmonics. In the validation process, measurement data should meet the given requirements to verify whether they are suitable for the task of validation. The application of the proposed model validation process to photovoltaic and wind power generation units with different topologies and power classes is thoroughly addressed as well. The application of the proposed process is illustrated in detail for selected harmonic orders from these measurement campaigns. This study aims to provide a scientific foundation for the consideration of the harmonic model validation of power generation units in future standards.
