Research Review of the Knowledge Graph and its Application in Power System Dispatching and Operation

open access: yesFrontiers in Energy Research, 2022
With the construction of a new power system and the proposal of a double carbon goal, power system operation data are growing explosively, and the optimization of power system dispatching operation is becoming more and more complex.

On the Powers of Signed Graphs

open access: yes, 2020
A signed graph is an ordered pair $Σ=(G,σ),$ where $G=(V,E)$ is the underlying graph of $Σ$ with a signature function $σ:E\rightarrow \{1,-1\}$. In this article, we define $n^{th}$ power of a signed graph and discuss some properties of these powers of signed graphs.

Power graphs: A survey

open access: yesElectronic Journal of Graph Theory and Applications, 2013
This article gives a survey of all results on the power graphs of groups and semigroups obtained in the literature. Various conjectures due to other authors, questions and open problems are also included.

The inner power of a graph

open access: yesArs Mathematica Contemporanea, 2010
Summary: We define a new graph operation called the \(k\)th inner power. The construction-which is somewhat analogous to the \(k\)th power with respect to the direct product-seems to lend itself nicely to certain questions concerning cancellation over the direct product.

A Comprehensive Approach to Synthetic Distribution Grid Generation: Erdős–Rényi to Barabási-Albert [PDF]

open access: yesAUT Journal of Electrical Engineering
In this extended study, the focus is on advancing the generation of synthetic distribution grids (SDGs) through the introduction of a new algorithm based on the Barabási-Albert random graph model.

Towards sparse matrix operations: graph database approach for power grid computation

open access: yesGlobal Energy Interconnection, 2023
The construction of new power systems presents higher requirements for the Power Internet of Things (PIoT) technology. The “source-grid-load-storage” architecture of a new power system requires PIoT to have a stronger multi- source heterogeneous data ...

On the tree-number of the power graph associated with some finite groups [PDF]

open access: yesAUT Journal of Mathematics and Computing
Given a group G, we define the power graph P(G) as follows: the vertices are the elements of G and two vertices x and y are joined by an edge if ⟨x⟩ ⊆ ⟨y⟩ or ⟨y⟩ ⊆ ⟨x⟩.
