With the development of smart grid technology, power energy efficiency evaluation will be driven to become more intelligent and professional. In order to achieve energy conservation and low-carbon economy, energy efficiency technologies need to be improved. The application of energy efficient technologies has to be enhanced from the supply side, power grid(More)
The use of nonlinear power electronic loads and new energy power generations make harmonic injection to the grid inevitable, lead to transmission line more additional harmonic losses and significant economic losses. Based on the mechanism of harmonic losses, this paper derived current density distribution formula for transmission line, a more precise(More)
