https://iecs.memberclicks.net/index.php?option=com_mc&view=mc&mcid=form_151236 Finally IEEE is revisiting the standard 1547 which concerns the connection of distributed energy resources. Currently the standard requires all of the distributed generators to produce unity power factor and have anti-islanding protection. Hopefully once the standard is revised, roof top solar can have smart inverters which control node voltage as well, significantly improving grid efficiency. It could also pave the way for move Vehicle-to-Grid services such as voltage regulation from the EV inverter while charging. Here's hoping.
