An isolated 50 Hz synchronous generator is rated at 15 MW which is also maximum continuous power limit of it's prime mover. It is equipped with a speed governor with 5% droop. Initially, the generator is feeding three loads of 4MW each at 50 Hz. One of these loads is programmed to trip permanently if the frequency falls below 48 Hz. If additional load of 3.5 MW is connected, then the frequency will settle down to
