Clearly the most economical answer in this case is the local generation in any of the several possible ways. Only as a theoretical exercise, we can try an a.c. solution with underwater cable. At 50Hz it happens approximately as follows:
1) 10kV, 3x120mm2 Cu, 100kW + 40kvar load, 2 reactors of...
A synchronous generator is, by its own nature, a rather high impedance device. Without field regulation, the terminal voltage depends strongly on the load, particularly on the reactive component.
In island mode, a quick acting AVR is always necessary in order to mantain the terminal voltage...
