Knowledge graph-based method for identifying topological structure of low-voltage distribution network [PDF]
The correct topological relationship is crucial in the low-voltage distribution network, as the actual topological structure of the low-voltage distribution network changes frequently and tremendously due to the need of operation and maintenance, and it ...

Coalition Graph Game-Based P2P Energy Trading With Local Voltage Management
In this paper, the feasibility of peer-to-peer (P2P) energy trading in a voltage-constrained grid-connected network is studied. In particular, a local voltage management scheme is proposed that takes network constraints into consideration to instruct the prosumers to trade energy frequently in the P2P market.

Orientable Hamilton Cycle Embeddings of Complete Tripartite Graphs II: Voltage Graph Constructions and Applications [PDF]
AbstractIn an earlier article the authors constructed a hamilton cycle embedding of in a nonorientable surface for all and then used these embeddings to determine the genus of some large families of graphs. In this two‐part series, we extend those results to orientable surfaces for all .

Generalised voltage graphs [PDF]
A graph with a semiregular group of automorphisms can be thought of as the derived cover arising from a voltage graph. Since its inception, the theory of voltage graphs and their derived covers has been a powerful tool used in the study of graphs with a significant degree of symmetry.

ACCURATE PREDICTION OF VOLTAGE OF BATTERY ELECTRODE MATERIALS USING ATTENTION BASED GRAPH NEURAL NETWORKS [PDF]
Performing first-principles calculations to discover electrodes' properties in the large chemical space is a challenging task. While machine learning (ML) has been applied to effectively accelerate those discoveries, most of the applied methods ignore ...
