The fuel cost models (in Rs/Hr) of the thermal plants of system shown are: F1=0.025P12+35P1+1500 and F2=0.03P22+34P2+2000. When certain load demand is optimally dispatched, it was found that the optimal generation of plant-1 is 216.115 MW and power loss is 23.3528 MW. Determine the optimal generation of plant 2, cost of received power, total load demand, total fuel cost and penalty factors. Also analyze the effect of not coordinating the transmission loss on total fuel cost and transmission loss when optimally dispatching the same total load demand found above and comment on the results.
