“…Based on the available scientific works, e.g. models shown in [3][4][5][6][7][8][9][10], it can be concluded that the reduction of model complexity does not lead to poor performance in comparison with the state-of-the-art models used in the literature, as long as the devices in question satisfy the given assumptions of angle distributions.…”

“…Based on the results, authors of this paper concluded that proposed aggregate models were suitable for preserving full information on the electrical characteristics of the modelled load mix. This approach was further developed in [8]. The main contribution of this work is a combination of detailed component-based modelling approach with the Markov-chain Monte Carlo routine allowing to account on user-load interaction.…”

“…The impact of computer power supplies and other electronic equipment on the network has been discussed in [26]. Similar studies have also estimated the impact of computer power supplies and other new harmonic sources on the grid [27,28]. Most computer power supplies incorporate passive PFC circuits due to strict emission standards [29].…”

Time Dependency of Current Harmonics for Switch-Mode Power Supplies

et al. 2020

This paper presents the time-dependent variance in the current harmonics emission by power supplies during power quality measurements. Power quality problems are becoming more significant with the adoption of power electronic-based circuits such as power supplies. The switch-mode power supplies are widespread as industrial, commercial, and domestic electrical loads. They draw non-sinusoidal current from the utility and inject current harmonics. Therefore, they are the reason for poor power quality and reduction in the power factor. The current harmonics emission from these power supplies depends on the circuit topology, operating conditions, and filter inside them. The harmonic emission estimations are critical for network operators; however, various uncertainties have made it a complicated task. The time-dependent stability affects the magnitude and phase angle of the harmonic current measurements and estimation of power quality indices. This paper investigates the variation in current harmonics emitted by the power supply during the initial unstable period under constant load and operating conditions.

“…However, as also stated in the literature review in [8], the problem is that the majority of already published works are focused only on specific customer categories or they are based on extensive measurements. In [9], a probabilistic approach for developing time‐varying harmonic current emission models of the residential customers is presented. In [10], a stochastic model of harmonic emission of aggregate residential customers is developed using a measurement‐based approach.…”
