Trajectories entropy in dynamical graphs with memory [PDF]

Frontiers in Robotics and AI, 2016
In this paper we investigate the application of non-local graph entropy to evolving and dynamical graphs. The measure is based upon the notion of Markov diffusion on a graph, and relies on the entropy applied to trajectories originating at a specific ...

Voltage Graphs and Cluster Consensus with Point Group Symmetries [PDF]

, 2016
A cluster consensus system is a multi-agent system in which the autonomous agents communicate to form multiple clusters, with each cluster of agents asymptotically converging to the same clustering point. We introduce in this paper a special class of cluster consensus dynamics, termed the $G$-clustering dynamics for $G$ a point group, whereby the ...

Development of coordinated control method based on Graph search method between EV and DG for voltage regulation

International Journal of Electrical Power & Energy Systems
In this paper, a study is conducted to solve voltage problems that may occur, when large-scale Distributed Generations (DGs) and Electric Vehicles (EVs) are connected to the distribution system, through coordinated control between DGs and EVs.

Knowledge graph-based method for identifying topological structure of low-voltage distribution network

The Journal of Engineering, 2020
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 ...
