Embodiment 1

[0025] to combine figure 2 As shown, an energy router applied to an island microgrid includes 2 AC converters and 1 DC converter. Each AC converter has the same structure, and the AC side of each AC converter is connected to a microgrid respectively. The DC side of each AC converter is connected to the DC bus; each DC converter has the same structure, and one side of each DC converter is respectively connected to a DC microgrid, and the other side is respectively connected to the DC bus. The AC port is mainly connected with the distribution network system. The low-voltage DC port of the DC converter can be connected to DC equipment such as energy storage devices, distributed power sources, and electric vehicle charging devices. Among them, the AC converter includes a power frequency transformer, an LC filter and a three-phase half-bridge circuit connected in sequence, and the AC microgrid realizes electrical isolation through the power frequency transformer to meet the volta...

Abstract

The invention discloses an energy router applied to an island micro-grid and belongs to the technical field of internet of energy. The energy router applied to the island micro-grid comprises N alternate current converters, M direct current converters and an energy router control module; the alternate current converters are in the identical structures, the alternate current side of every alternatecurrent converter is connected with one micro-grid, and the direct current side of the alternate current converter is connected with a direct current bus; the direct current converters are in the identical structure, one side of every direct current converter is connected with one direct current micro-grid, and the other side of the direct current converter is connected with the direct current bus; the energy router control module issues power scheduling instructions according to the energy information of every micro-grid. The energy router applied to the island micro-grid achieves power connection of alternate current micro-grids and direct current micro-grids, and achieves connection and disconnection between three micro-grids through three port switches.

Description

technical field [0001] The invention relates to the technical field of energy Internet, in particular to an energy router applied to a sea-island microgrid. Background technique [0002] With the rapid development of my country's marine industry, the development and utilization of marine resources has been listed as a major strategic measure for economic construction, and the protection, development and management of islands have become the focus of marine industry in the new century. Reasonable and orderly development of marine resources will greatly alleviate the contradictions between economy, resources and environment faced by current land development. China has always paid attention to the development and utilization of island resources, and the development and utilization of islands requires energy as a thrust. But generally speaking, most islands face problems such as shortage of fossil fuels, difficulties in transportation, remoteness and difficulty in connecting wi...
