- toomuchtodo 2y agoUtility scale solar inverters can as well! Renewables and batteries have graduated from grid following to driving grid health. Exciting times. https://www.nrel.gov/grid/grid-forming-inverter-controls.html https://www.nrel.gov/grid/grid-forming-inverter-controls.htm... https://spectrum.ieee.org/electric-inverter https://spectrum.ieee.org/electric-inverter
- yarekt 2y agoAll (grid tied) inverters technically provide that function. An inverter doesn’t just generate 50/60 Hz sine, it supplies power by attempting to slightly “push” the frequency higher, i.e lead, to provide power. if there’s no more power to provide, it “pushes less”. It’s very weird, indeed
- rightbyte 2y agoReally? Isn't it trying to raise the voltage over the sine? (Note, a question. I have no clue).
- yarekt 2y agoAC voltage must stay within spec, and the grid has voltage control in place, but that’s not what determines the direction of power flow. Like, what makes the inverter output power rather than draw it? In fact that’s how individual sections of the grid set power flow limits, by ensuring they stop leading when they reach their max capacity. fascinating really
