How to work with 2 or more AC Voltage sources simultaneously?

Hello!

I think I have a simple or complex question, but I want to know if there's a way to use two or more AC Voltage sources to supply a system.

I made a simulation with Proteus software and it's working exactly at the same way that works the DC Voltage sources in series:

|500x448

The main thing is to work safely and the purpose is to make a Smart Grid, which could be able to measure voltage on each source to know who exactly needs to add power supply to the system. Also I want to know if there's going to be a power issue to work with different sources with different power capabilities.

Hope to receive an answer soon! Thanks :)

You miss interpret "smart grid". It does not add voltage to a power grid. It drops loads until the designed power level is attained.

If you are trying to add generating power to a grid, it is done in parallel, not in series.

More information would be useful - are these sources phase-synchronized? Are they even at the same
frequency? Do they have the same source impedance? Are they floating or referenced to some ground
or earth?

Change your simulation. Try making one of the voltage sources 60.1Hz. You will rapidly notice that the output voltage goes all over the place.

IF the voltage sources are PERFECTLY synchronised, such as two alternators on the same shaft, then this will work. In no other situation will this work. You need some other way of adding AC voltages. The big boys rectify everything to DC, add it together and then convert back to AC. This is by no means cheap.
