In recent years the undergraduate engineering curriculum of several areas has started to incorporate the study of harmonic distortion on electrical systems. Several education simulation tools have been developed and investigated, most of them a short time ago. However, to the best of our knowledge, there is not any literature review on this topic. In this work, we present for the first time a systematic survey on educational tools to model and simulate the effect of power harmonics on industrial electrical networks. As a result, several improvement aspects have been identified and recommendations and implications for future research have been provided. For that, a retrospective study has been accomplished, showing a growing trend toward simulation and modeling. The key teachers’ perceptions to incorporate these practices are the ease of the teaching‐learning process and the importance of modeling and simulation in the industry. The main research challenge is the conduction of integral assessments that comprise both tools’ quality and use experience, and their contribution to achieve learning outcomes. Statistical tests should be used to validate the academic results obtained. This is a major challenge, since only a few of the existing studies incorporate such tests. Other implications for future research refer to the involvement of a higher number of students in the evaluations and the use of free software in the development of the applications.

“…Electrical loads are analyzed in two groups: static and dynamic loads [20][21]. Due to the fact that the traditional static load models are not sufficient to represent the transient behavior of real electrical loads, there is a need for the dynamic load modeling in electrical system simulations.…”

Smart grid is a developing field for energy researchers. It offers technological improvements to have more controllable, reliable and sustainable power grids. Especially, the decreasing trend of fuels has pressurized to pay researchers' attention to renewable energy sources such as solar systems and wind turbines. The renewable energy sources generate electric power in different characteristics. Therefore, power converters are needed to integrate these sources in a grid to provide power flows among the sources and loads. This study presents Matlab/Simulink models of power converters and dynamic load structure, which are useful for smart grid simulations. These simulations can be used for research and educational purposes. Characteristic parameters of the models are suitable for existing devices. For power converters, Pulse-width Modulation technique is utilized that it is widely used in industry. The designed power converters and dynamic load models are tested in a microgrid application. The simulation results show that the designed power components are useful for smart grid simulation studies.

“…The generated periodic discontinuous current involves fundamental and odd harmonics components. These harmonics cause problems for the power distribution systems such as additional losses and dielectric stresses in capacitors and cables resulting in increasing peak currents in windings of rotating machinery, transformers and bringing about unwanted operations of relays [5]. These rectifiers have also the problems of poor power quality in terms of poor power factor at input AC mains, slowly varying rippled DC output at load end and large size of AC and DC filters [6].…”

“…As one of these techniques, an active PFC boost power electronic rectifier provides a stable level at the output DC voltage, a high-power factor at the input AC power and also draws nearly sinusoidal current from the supply. These advantages make active PFC boost rectifier a popular configuration for AC/DC power conversion applications [5].…”

Static series compensator (SSC) topologies including shunt connected power electronic rectifier with no energy storage have some potential advantages such as an extra saving and the ability exists to compensate longer dips. However, this topology has the disadvantage that the uncontrolled DC link is connected to the supply with a shunt rectifier during the fault, and more importantly, the conventional diode bridge rectifier (C-DBR) does not draw sinusoidal current from the supply and inject current harmonics to the network. In this study, an improved topology for the SSCs using a single-switch active power factor correction (A-PFC) boost rectifier is proposed. Single-phase SSC topologies with load side shunt connected C-DBR and A-PFC are compared by obtaining the results for the DC-link voltages, the supply currents and the load voltages. The results show that the proposed new topology offers solutions to problems of the topology including C-DBR such as supply current harmonics and uncontrolled DC-link voltage and so a considerable performance improvement is achieved by using the proposed SSC topology.
