“…A prospective line for smart grids development is the use of power routers built with the use of high-frequency solid state transformers [11,12] in power supply systems (PSS). The power router performs the following functions: power flows management; data exchange; integration of distributed generation plants in PSS [12]. In addition, power router introduction into PSS allows to enhance consumers power supply reliability and power quality.…”

The increase in the trains weight and their operation speeds leads to considerable growth of abrupt-variable, non-linear and one-phase traction loads. This, in its own turn, leads to significant deviations, unsymmetry and voltage harmonic distortions in 110-220 kV mains adjacent to traction substations of AC railroads. Significant deterioration in power quality factors is observed in Siberian and Far East regions where 110-220 kV main power transmission lines are immediately adjacent to Transsib traction substations; in this case, in points with lower levels of short circuit power, power quality factors exceed by far the permissible levels. The articles provides the results of studies aimed at solution of power quality enhancement is-sues for mains adjacent to traction substations of Trans-Siberian Railway. To enhance power quality in mains supplying traction substations, smart grid technologies can be used together with multiagent control systems. Technical solutions, based on the results obtained, are proposed that allow to bring the power quality factors to the regulatory values. Due to a big investments amount, an implementation of tar-get program is needed to resolve the large-scale issue of enhancing power quality in mains adjacent to traction substations of AC railroads.

“…In [102], a modular converter based on an SST for PV power plants was detailed. In [103], an energy router based on a three-stage SST with a dual active bridge topology was proposed for designing power supply systems for non-railway consumers of the railroads, ensuring reliable integration of distributed generation plants operating with the use of RES. According to the authors, compared with a conventional transformer, the use of the energy router allows limiting short-circuit currents and reducing the consequent voltage sag value.…”

View full text Add to dashboard Cite

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.

“…Renewable energy is clean, flexible, widely distributed, and rich in resource. However, the output voltage, frequency, and power of renewable energy are unstable and are influenced by multiple parameters, such as weather, environment, and geographical conditions, which bring the big challenge for the operation of power grid in safety 1‐4 …”

“…The voltage and power output of each port could be separately controlled by manual instructions. With EPRs at the nodes of power grid, many advantages can be obtained, such as the enhancement of power flow management efficiency and flexibility, power supply reliability and power quality, and integration of renewable energy sources into power supply system 3 . Compared with the complicated control when connecting distributed generation to AC system, only voltage control is required when connecting to DC power grid 4 .…”
