Embodiment

[0027] The present invention first proposes the definition of electrical correlation strength and electrical correlation matrix, and on this basis, proposes the concept of regional compactness.

[0028] 1. Electrical correlation strength and electrical correlation matrix

[0029] In order to describe the size of the electrical connection between nodes, the composite weight of the two characteristic quantities of electrical distance (impedance) and effective transmission capacity between nodes is used to define the equivalent electrical connection strength between any two nodes v and w:

[0030]

[0031]

[0032]

[0033] Among them, Z vw Indicates the equivalent electrical distance (impedance) between node v and node w, C vw Indicates the effective transmission capacity between node v and node w. with is the corresponding network average. Its physical meaning is that the smaller the electrical distance between two nodes, the smaller the transmission loss; the la...

Abstract

The invention discloses energy internet construction method based on structure compactness, which comprises the following steps: determining strength of electrical association between nodes in a distribution network according to structural characteristics of the distribution network; evaluating the association compactness of an electrical structure of a divided distribution network region according to the strength of the electrical association between the nodes; and based on the association compactness of the electrical structure, a sub-region configuration resource with high electrical structure compactness is configured with a virtual microgrid corresponding to the resource construction. The invention provides a definition of electrical association strength and electrical incidence matrix of the distribution network, and the boundary of the virtual microgrid is defined according to the internal strong association of the local region of the network. Optimized deployment of distributedpower generation, energy storage and microgrid control facilities is unified and coordinated by using the divided virtual microgrid as a basic unit.

Description

technical field [0001] The invention belongs to the field of energy internet control and electrical technology, and specifically relates to an energy internet construction method based on structural compactness. Background technique [0002] With the introduction of the concept of Energy Internet, the construction of user-side energy network or energy local area network has become an important issue in the development of Energy Internet. However, the resource allocation and operation mode of the existing distribution network is built according to the early planning, which cannot meet the requirements of Energy Internet. The goals of freedom, reciprocity, flexibility, and autonomy. Therefore, building a microgrid with the advantages of autonomy, flexibility, and free interaction is considered to be a reasonable way to plan an energy local area network. However, there are very few micro-grids that have been built and put into operation. For large-scale distribution networks, ...
