Abstract

The invention discloses a new energy grid-connected or on-site consumption system based on an electric energy router. The system includes: AC power grid, power router and multiple power devices; the power router includes inductors, cascaded H-bridge bidirectional converters and multiple resonant isolated bidirectional DC / DC converters; multiple cascaded H-bridge bidirectional converters The AC side of the H-bridge topology is cascaded and connected to the AC grid through an inductor; multiple H-bridge topologies are connected to multiple resonant isolated bidirectional DC / DC converters one by one, and the DC side of the H-bridge topology is connected to the resonant isolated bidirectional DC / DC converter The primary DC side of the DC / DC converter is connected; the secondary DC side of the resonant isolated bidirectional DC / DC converter forms a DC bus, and the power equipment is connected to the DC bus; power equipment includes new energy equipment, energy storage battery equipment and loads equipment. The invention has the advantages of high efficiency, high reliability, wide gain, bidirectional transmission of energy, dynamic adjustment of power quality and the like.

Description

technical field [0001] The invention relates to the field of electrical automation equipment, in particular to a new energy grid-connected or on-site consumption system based on an electric energy router. Background technique [0002] With the gradual reduction of fossil energy, renewable energy such as wind power and photovoltaic power generation will be widely used in the future. In order to cope with the challenges brought by wind power and photovoltaics to the safe and stable operation of the power grid, a large-capacity battery energy storage system is also required to stabilize the power fluctuations of new energy sources, adjust peak frequency and improve power quality. [0003] First of all, due to the characteristics of high uncertainty, high uncontrollability, wide distribution, remote location, harsh operating environment, low equipment reliability, and heavy operation and maintenance workload of new energy power generation, with the increase in the number of new ...
