Two generators are supplying a common load of 1000 MW. The incremental cost curves in Rs/MWhr for both generators are shown in figure. The maximum and minimum generation limits are also indicated. The optimum generation schedule is:

A power of system network consists of 180 buses in which 15 buses among them have generator connected to it, 10 buses have reactive power support and rest are load buses. In a particular iteration of Newton Raphson method if reactive power limits are violated in two generator buses then the order of Jacobian in that iteration will be

The maximum demand of a power plant is 60 MW. If the utilization factor is 0.7 and capacity factor is 0.6,  the reserve capacity (MW) and load factor respectively will be ?
