Power Systems The incremental fuel costs for two generating units G1 and G2 are given by Ic1 = 25 + 0.2 PG1 and Ic2 = 32 + 0.2 PG2, where PG1 and PG2 are real powers generated by the units. The economic allocation for a total load of 250 MW, neglecting transmission loss, is given by PG1 = 100 MW and PG2 = 150 MW PG1 = 125 MW and PG2 = 125 MW PG1 = 109.75 MW and PG2 = 140.25 MW PG1 = 142.5 MW and PG2 = 107.5 MW PG1 = 100 MW and PG2 = 150 MW PG1 = 125 MW and PG2 = 125 MW PG1 = 109.75 MW and PG2 = 140.25 MW PG1 = 142.5 MW and PG2 = 107.5 MW ANSWER DOWNLOAD EXAMIANS APP

Power Systems A load centre is at an equidistant from the two thermal generating stations G1 and G2. The fuel cost characteristics of the generating stations are given by F1 = a + bP1 + cP²1 F2 = a + b P2 + 2cP²2 Where P1 and P2 are the generation in MW of G1 and G2, respectively. For most economic generation to meet 300 MW of load, P1 and P2 respectively, are 150, 150 100, 200 200, 100 175, 125 150, 150 100, 200 200, 100 175, 125 ANSWER DOWNLOAD EXAMIANS APP
