Electrical and Electronic Measurements Question on Measurement of voltage

Assume the incremental cost characteristics of two generates delivering 250MW as.
dF1dP1=20+0.01P1\frac{dF_1}{dP_1} = 20 +0.01P_1
dF2dP2=14+0.2P1\frac{dF_2}{dP_2} = 14 +0.2P_1
For economic operation, the generation P1 and P2 should be:

A

P1 = P2 =125MW

B

P1 = 209.5MW; P2 = 40.5MW

C

P1 = 250MW; P2 = 0MW

D

P1 = 40.5MW; P2 = 209.5MW

Answer

P1 = 209.5MW; P2 = 40.5MW

Explanation

Solution

The correct option is(B): P1 = 209.5MW; P2 = 40.5MW
