Abstract

The invention discloses a microgrid management system, comprising a region management system, at least one power distribution device and a node management system integrated in the power distribution device. The power distribution device comprises a grid-connected system branch connected to a big power grid, a microgrid branch connected to the microgrid and a load branch connected to a load; all branches are connected to a microgrid bus in the power distribution device; the region management system utilizes a region management strategy to calculate electric energy information of each branch which is uploaded on the node management system or obtains a node control order according to a scheduling order inputted by the user; the node management system collects electric energy information of various branches, utilizes the node management strategy to calculate the electric energy information or obtains a branch control order according to the node control order, and respectively controls each of the branches in the power distribution device according to the branch control order. The microgrid management system reasonably controls and coordinates power flow among the power grid, a distributed power supply, an energy storage system and the load, and guarantees safe, stable and reliable operation of the system.

Description

technical field [0001] The invention relates to the technical field of microgrid applications. More specifically, it relates to a microgrid management system. Background technique [0002] Renewable power as an emerging energy has been vigorously promoted and applied by countries all over the world, but renewable energy itself has randomness and volatility, and large-scale access also has a huge impact on the power grid, while the microgrid system itself has certain adjustment capabilities , not only can weaken the impact of renewable energy on the power grid, increase the access ratio of renewable energy, but also meet the diversified needs of users for electric energy. At present, there are many theoretical research results on micro-grid technology, but there are few engineering application researches on micro-grid-related management systems, which makes it difficult to instantiate and popularize micro-grid technology. [0003] Therefore, it is necessary to provide a mic...
