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 175, 125 150, 150 200, 100 100, 200 175, 125 150, 150 200, 100 100, 200 ANSWER DOWNLOAD EXAMIANS APP
