Selection of Power Generation Unit in Load Curve: The load on a Power Generation Unit is seldom constant; it varies from time to time. Obviously, a single generating unit (i.e., alternator) will not be an economical proposition to meet this varying load. It is because a single unit will have very poor efficiency during the
