ПРИСТРОЇ СИЛОВОЇ ЕЛЕКТРОНІКИ В SMART GRID

The effective resolution of technical problems on the Smart Grid implementation depends on the power electronics capabilities. The goal of the article is to systematize the circuit topology of power electronics converters relating to Smart Grid application. If we consider the Smart Grid as part of an alternative to the unified energy system, it is possible to select the multiple baselines of its organization.We have applied system analysis method for forming a three-level hierarchy of converting systems for smart grids. The first level is associated with preservation of existing network structures with electric power AC transmission. The second level is determined a connection between the networks with vary electric power parameters. The third level is formed by objects of distributed generation – alternative energy sources, consumers and energy storages.We have presented modern converters implementation solutions for flexible alternating current transmissionsystem, high-voltage direct current transmission and distributed generation and energy storage. The most perspective flexible alternating current transmission system for Smart Grid application such as static synchronous compensator, static synchronous series compensator, unified power flow controller, interline power flow controller, interline power flow controller are considered.We have elucidated an issue that using advanced modular and multilevel converter structures for flexible alternating current transmission system, high voltage and medium voltage direct current transmission system would be the most appropriate solution. The third hierarchical level occupied by the most numerous converters, intended for connection of distributed generation plants with renewable energy sources, energy storages, different types of consumers and power active filters. The most perspective for Smart Grid application converters such as active rectifier voltage source, parallel and series active filter, Z-source inverter, multilevel inverter, Multi-Port, MultiStage Convertor, Boost Converter, Buck Converter, Buck-Boost Converter, PWM Full-Bridge Converter, resonant converters, Current-Fed Two-Inductor Boost Converter, Bidirectional Current–Fed Converter, Dual Active Bridge, High Step-Up Converter, Matrix Converter are considered.В соответствии с предложенной трехуровневой иерархией проведена систематизация преобразовательных устройств силовой электроники для интеллектуальных электроэнергетических системВідповідно до запропонованої трирівневої ієрархії проведена систематизація перетворювальних пристроїв силової електроніки для інтелектуальних електроенергетичних систе
