“…High-frequency transformers can be used to implement the isolated bidirectional converters, which enables for equipment that is smaller, lighter, and less expensive. Since the non-linearity and losses of the low-frequency transformers are eliminated from the system, it is also anticipated that the UPQC will perform better in compensating the power quality issues and have a higher efficiency as its series and shunt converters connect to the power grid without transformers [70].When the circulating power between the series and shunt converters is low and there is little power loss in the isolated bidirectional dc-dc converters, the efficiency enhancement is most apparent [71].…”

“…The isolated bidirectional converters can be implemented using high-frequency transformers, which allows for reducing the size, weight, and cost of equipment. As the series and shunt converters of the UPQC connect to the power grid without transformers it is also expected a better performance of the UPQC in compensating the power quality problems and a higher efficiency since the non-linearity and losses of the low-frequency transformers are removed from the system [242]. The increase in the efficiency is most noticeable when the circulating power between the series and shunt converters is small, leading to low power loss in the isolated bidirectional dc-dc converters [243].…”

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.
