Optimal reconfiguration of distribution network
International Journal of Engineering & Technology, 2018 This paper proposes a simple method for solving the distribution system reconfiguration to improve the voltage profile and reduce the losses. In this paper power flow studies are used in matrix form of distribution system with radial, weakly meshed and reconfigured forms.

A Submodular Approach for Electricity Distribution Network Reconfiguration [PDF]
Proceedings of the Annual Hawaii International Conference on System Sciences, 2018 Distribution network reconfiguration (DNR) is a tool used by operators to balance line load flows and mitigate losses. As distributed generation and flexible load adoption increases, the impact of DNR on the security, efficiency, and reliability of the grid will increase as well.

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3
Advanced Functional Materials, EarlyView.Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...
