flywheel nonsense, just add battery.
Riddle me this, what instantaneous voltage should an inverter target if the grid's at a fault condition? Stated another way, how do you define the frequency of a non-sinuoid?
Careful, get the wrong answer and you get a short and you help melt millions of dollars of equipment, some with year old lead times.
you can island and not island at same time. decentralized grid means DECENTRALIZED grid.
every renewable needs battery next to it.
The trick is measuring a frequency in the 60s of Hz of a non-sinusoid within a thousandth of a second.
Otherwise you get a short.
Flywheels are batteries. If your model is predicated on a particular chemistry of battery, it’s overfitted.
