A Review on Power Electronics Technologies for Power Quality Improvement

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