IEEE 1547 Revision Workshop

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.

Currently the inverters must spit out unity power factor power. If there are many solar installations on the same distribution transformer or area of the network, this can lead to voltage rises which will result in shutting off some of the solar. Smart inverters would have full spectrum reactive power control and therefore could lower or raise the voltage as needed to allow more solar on the grid as well as improve its voltage profile.
