Problems solved by technology

Moreover, the current construction method is still collected according to the area, and the method of centralized inverting and connecting to the grid leads to the inability to collect energy in small areas and inefficiency
And if a large number of factories are built, it will take up a lot of space
[0005] At the same time, ordinary households are still only consumers of electric energy and cannot participate in the production of electric energy.
Moreover, the distance between power producers and consumers is far away, and the structure of the main grid----branches is often used. In this way, the main grid lines are wasted and the regional load remains high.

Embodiment Construction

[0041] The technical solution of a distributed power grid system involved in the present invention will be described in further detail below with reference to the drawings and embodiments.

[0042] see figure 1 As shown, an embodiment of the present invention provides a distributed power grid system, which includes a primary node, a secondary power network, a first user, a second user, a third user...the Nth user. Each user is connected to the secondary power network through its own secondary node, and the secondary nodes are connected in parallel. The first-level node can coordinate the exchange of electric energy between different second-level nodes through the second-level power network.

[0043] Further, the nodes at all levels have functions such as energy storage, (parallel, off-grid) inverter, DC charging, human-computer interaction, networking, communication functions, etc., the functions listed above are just examples, and, in practical applications, each Level node f...

Abstract

The invention provides a distributed power grid system, comprising a first-grade node, a second-grade power network, a first secondary-grade node, a first user, a second secondary-grade node, a second user, a third secondary-grade node and a third user, wherein a power device of the user performs the power energy exchange through the respective second-grade node and the second-grade power network; the first-grade node can coordinate power energy exchange between the different second-grade nodes through the secondary-grade power network.

Description

technical field [0001] The invention belongs to a grid system in the field of electric power, in particular, a distributed grid system used for distributed grids. Background technique [0002] With the development of society, human beings' demand for energy is getting higher and higher. And because the consumption of fossil energy will have a fatal impact on the environment, therefore, the human desire for clean energy is becoming stronger and stronger. Common clean energy sources include wind energy, solar energy, and geothermal energy. [0003] However, for the actual collection of clean energy, there are more or less disadvantages. For example, wind power generation is unstable and cannot be connected to the grid in time; or wind and solar energy in a certain area is excessive and cannot be exported to the user's power consumption area. [0004] In addition, for the site selection of geothermal energy, wind energy, and solar energy collection, large-scale energy-enrich...
