Hello
If there are two synchronous generators installed, one is operating in isochronous mode and the other in droop, then I understand that as grid load changes, the generator in isochronous mode will regulate fuel to its prime mover to maintain system frequency. Speed of generators in droop will mode will not cahnge if the generator in isochronous is doing it job properly. I understand that the generator in droop is typically used to accomodate load forecasts by being able to vary its output power based on grid demand, such that the generator in isochronous is not inadvertantly tripped if load fluctuates too much.
If we connect a renewable source (such as solar PV or battery facility) to the grid and we want to export power from these facilities based on power availability, is it best to keep the same arrangement with the synchronous generators? My understanding is that the renewable facilities will act as virtual synchronous generators. So, if we increase the power from the renewable facilities, then the isochronous generator will decrease power output by speeding up/slowing down based on the change in grid frequency. Operators can then equalise the generators (if required) by adjusting the power output of the generator in droop mode. Is this typically how these control systems operate ?
