AI Technical Summary

Problems solved by technology

Existing research on energy routers mainly focuses on AC networks and hybrid AC-DC networks, and most of them focus on local area networks and backbone networks. There are few studies on energy interconnection control strategies for off-grid island microgrids and multi-short-distance island microgrids.

Embodiment Construction

[0024] The solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 As shown, the multi-microgrid control system based on the energy router realizes the power connection of the frontier defense microgrid, the maritime microgrid, and the DC microgrid through the energy router. The voltage of the two AC microgrids is AC 380V, and the voltage of the DC microgrid is 48V. The energy router coordinates the energy flow between the border defense microgrid, the maritime microgrid and the DC microgrid, and the energy of the three interfaces flows in both directions. At the same time, the energy router can act as an energy provider of a microgrid, and can also be regarded as a load of another microgrid, transmitting energy between networks on demand.

[0026] In this embodiment, the border defense microgrid is composed of photovoltaic power generation system, lead-acid energy stor...

Abstract

The invention discloses a multi-microgrid control system and method based on an energy router. The system comprises a frontier microgrid, a maritime microgrid, a direct current microgrid and an energyrouter, wherein the frontier microgrid, the maritime microgrid and the direct current microgrid are all connected with the energy router; the energy flow among the frontier microgrid, the maritime microgrid and the direct current microgrid is coordinated through the energy router; and the method determines a control strategy according to the operation state of the microgrids. The scheme of the invention can realize the combined power flow power control of a plurality of island microgrids with different grid structures.

Description

technical field [0001] The invention relates to micro-grid control technology, in particular to an energy router-based multi-micro-grid control system and method. 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. The development and utilization of islands requires energy as a propulsion, but generally speaking, most islands face problems such as shortage of fossil fuels, difficulty in transportation, remoteness and difficulty in connecting with the mainland. The existing diesel power generation system is difficult to guarant...
