Question
Electrical and Electronic Measurements Question on Measurement of voltage
Assume the incremental cost characteristics of two generates delivering 250MW as.
dP1dF1=20+0.01P1
dP2dF2=14+0.2P1
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
