Reply to comment by mastapsi in The US's National Renewable Energy Laboratory wants to make decentralized microgrids as simple to set up and operate as diesel generators, and has created a prototype that is much simpler than existing microgrid technology. by lughnasadh

This is what it sounds to me but also this sounds like the battery is the controller. Is there some natural tendency in the system to increase the frequency when supply is bigger than the load?

Yes, when you have three phase prime movers (whether that is a motor or a generator). When a generator is over-generating for its load, it will spin faster and frequency will increase. When it is under-generating it will slow down and frequency will decrease. Similar for three phase motors, if there is too much power going into the motor, it will spin faster and force the frequency up, and vice versa.

If there are no three phase prime movers, then there is no natural tenancy for this. In the case of the microgrid, it's entirely manufacturers for signaling purposes.

I see so this system is mimicking the system already used in generator and at the same time allows existing diesel generators to also tie into the micro grid
