Using the examples of wave and vector diagrams, we study conditions for appearance components inactive power in an AC network, which are known as reactive distortion power. It is shown that active, mutually orthogonal form a balance, can be violated mainly due to methodological errors calculating these under non-stationary mode parameters. established interaction occurs at instantaneous level, ...

one of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. the cars intensify greenhouse gas emission in civic centers. one approach to reduce the emission is replacing the cars by plug-in electric vehicles (pevs). in spite of reducing the emission, pevs have some adverse effect on electric distribution networks. technical challenges such as load and...
