The increased use of electricity-dependent devices has posed many concerns to the power industry. The devices like electric motors, printers, generators, transformers, computers, etc are widely used in today’s world. The electronic devices increase the non-linear load to the power system which leads to the power quality (PQ) issues by which the electrical devices may get affected with fluctuation causing equipment failure, power system failure, etc. In order to resolve the PQ related issues and harmonics mitigation occurred due to nonlinear load power filters were introduced in decades ago. This paper deals with the review of existing researches that uses power filters and other methods for power quality improvement. The paper also gives gaps and the current state of the art in the recent researches which have futuristic scope in the research domain.

“…Mitigation of power quality distortions is an active topic of research [4]. Studies in this field agree that to properly mitigate power quality distortions it is essential to detect the occurrence of the distortions and to identify their specific types [5]. Many automatic classifiers of power quality distortions have already been developed [1].…”

Automatic classification of power quality distortions has gained interest in research due to the proliferation of distributed power systems with renewable sources. To train and test a classification system, data with power quality distortions are required. Most studies generate synthetic data from mathematical equations, since real distortions are difficult to record. A possible alternative is to use public datasets of real disturbances. However, there are strong differences among public datasets. In this paper, existing datasets of power quality distortions were compiled and their main features were analysed and compared. To the best of our knowledge, this is the first work reviewing these datasets. To identify the datasets, the most cited papers on this topic were surveyed. In addition, systematic searches were conducted in four popular scientific repositories. As a result, four available datasets were identified. They included a limited number of samples (20-44) and types of distortions. Sampling frequencies and recording conditions were appropriate and the two main fundamental grid frequencies (50 and 60 Hz) were also considered. Although these datasets are appropriate for partially testing automatic classifiers, a remaining research effort is to provide comprehensive datasets with hundreds of samples and several types of distortions.

“…The unbalancing power consumption nature is determined by the electrical receiver's type. And if in industrial premises, where motor and other three-phase symmetrical loads prevail over single-phase electric receivers, the currents and voltages negative sequence components have the greatest values [7][8][9][10][11][12][13], then in rooms containing 1045 (2022) 012145 IOP Publishing doi:10.1088/1755-1315/1045/1/012145 2 mainly communal single-phase electric receivers, it is the zero sequence currents and voltages symmetrical components that take the greatest importance [14][15][16][17][18][19]. The criterion for evaluating additional active power losses is the power loss coefficient, which represents the active losses ratio in an unbalance mode to the corresponding losses caused by the positive sequence currents flow only [20]:…”

The article shows that the operation modes in three-phase four-wire 0.38 kV electrical networks are objectively associated with unbalancing power consumption. As a result, significant additional electrical energy thermal losses occur in the neutral conductor’s internal electrical networks and external electrical networks l elements, which not only increase the electrical energy consumption, but also create conditions for the fire-hazardous occurrence single-phase short circuits. A mathematical model is proposed, an algorithm and a program for calculating the limit zero sequence values flows in external neutral conductors and internal 0.38 kV electrical networks are developed. Numerical calculations are made and tabular these limit values data for different conductors’ sections made of various conductive materials are presented. The unbalancing operation modes calculations in operating external and internal 0.38 kV electrical networks have been made, on the basis of which the proposed methodology has been tested. The technical means use effectiveness for the operating modes balancing in existing electrical networks with unbalance power consumption is proved.
