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 = 109.75 MW and PG2 = 140.25 MW PG1 = 100 MW and PG2 = 150 MW PG1 = 125 MW and PG2 = 125 MW PG1 = 142.5 MW and PG2 = 107.5 MW PG1 = 109.75 MW and PG2 = 140.25 MW PG1 = 100 MW and PG2 = 150 MW PG1 = 125 MW and PG2 = 125 MW PG1 = 142.5 MW and PG2 = 107.5 MW ANSWER DOWNLOAD EXAMIANS APP

Power Systems A lossless power system has to serve a load of 250 MW. There are two generators(G1 and G2) in the system with cost curves C1 and C2 respectively defined as follows: C1 = PG1+0.055P²G1 C2 = 3 PG2 + 0.03 P²G2 Where PG1 and PG2 are the MW injections from generators G1 and G2 respectively. Thus, the minimum cost dispatch will be PG1 = 150 MW and PG2 = 100 MW PG1 = 250 MW and PG2 = 0 MW PG1 = 100 MW and PG2 = 150 MW PG1 = 0 MW and PG2 = 250 MW PG1 = 150 MW and PG2 = 100 MW PG1 = 250 MW and PG2 = 0 MW PG1 = 100 MW and PG2 = 150 MW PG1 = 0 MW and PG2 = 250 MW ANSWER DOWNLOAD EXAMIANS APP
