It seems this inverter uses internal grid-forming method to control the voltage and frequency, and all energy resources follow the voltage/frequency produced by inverter. Am I correct?
Another scenario is during off-grid situation, this inverter get a voltage/frequency sample of one of the...
Few post earlier, some guys said, inverters convert DC to AC or vice versa, but Gen is produced AC voltage and connected to AC bus.
So can we use inverter for it?
The following project shows the integration between PV, BESS, and generator in a microgrid.
I would like to know these 3 inverters are enough for control the whole system?
Why there isn't any inverter for battery and generator?
What is PCS and STS?
We don't have any converters in this system?
So you are talking about this kind of inverter. Right?
Assume we have diesel generator for back up during outage. How can we control voltage and frequency or power of microgrid?
But they can not flow the power and manage the whole energy in micro-grid. So I guess, besides the inverters (battery/PV inverters), we need centralized controller to control and manage the energy in micro-grid.
So, it works like EMS. Right?
Is the control strategy "droop control" in it?
What's your control strategy when you face with grid outage? This controller can manage it?
Thanks. But beside the inverters, we need to have separate controller (energy management system) to control and manage the power flow. Like the following picture.
