Abstract

An energy router for electric energy quality comprehensive control and power optimization comprises a series transformer, a grid side isolation converter, a load side converter, a function switching switch Si, and a centralized controller. The invention provides a novel low-voltage energy router which integrates a unified electric energy quality controller and a power optimization function and a control method thereof. Through the novel low-voltage energy router arranged between a network-side high-voltage AC bus and a load-side low-voltage AC bus of a smart distribution network, the control method determines the fault condition according to the sampling signal provided by the detecting unit, performs function selection, generates control commands and performs control, and realizes power quality comprehensive management and power optimization functions with minimum hardware cost. The energy router and the control method thereof can be widely used in factories, businesses, homes and schools.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and specifically relates to a new low-voltage power quality controller (UPQC, Universal Power Quality Controller) and an energy router that integrates the functions of an intelligent distribution network for comprehensive management of power quality and power optimization. Energy router and control method thereof. Background technique [0002] In order to meet the user's requirements for power supply reliability and power quality, and to meet the large-scale application of distributed power sources, the functions of the traditional distribution network need to be improved urgently. The smart distribution network is the cornerstone of a strong smart grid. power grid. [0003] The unified power quality controller connects the series converters and parallel converters through the common DC bus, and simultaneously solves the voltage power quality problem of the power supply system and the ...
