A Thermal-Electric Cloak via Nonlinear Transformation

A thermal-electric invisibility cloaking is designed by a nonlinear transformation, which can guide both electric current and heat flux around the concealed region and restore their original diffusion directions.Compared with previous thermal-electric cloaks designed by linear transformation, the proposed thermal-electric cloak by nonlinear transfo

Design and evaluation of a multi-level reactive power market

Abstract The shift from conventional power plants on transmission level to distributed energy resources in the distribution grids requires procedures to enable efficient and economic reactive power exchange across different voltage levels.In this paper, we propose a multi-level reactive power market that enables reactive power provision from distri
