Activity 2:
An area of an interconnected power system has two fossil-fuel units operating on economic dispatch.
The variable operating costs of these units are given by:
C1 = 10P, + 8 * 10-3 P? $/hr
C2 = 8P2 + 9 * 10-3 P? $/hr
The total transmission loss for the power system is given by:
PL = 1.5 * 10-4 p? + 2 * 10-5 P,P, + 3 * 10-5 P?
Where P, is the output power of generator 1 and P, is the output power of generator 2. P1 and P2 are
in megawatts.

aP1.
Using the incremental operating costs, we will get the following two equations:
10 + 16 * 10-3P1
= 16
1- (3 * 10-4P + 2 * 10-5P2)
8 + 18 * 10-³P2
1- (3 * 10-4P2 + 2 * 10-5P1)
= 16
1. Rearrange the above two equations.
2. Write the set of equations in matrix form (A.x = b).
3. Find the determinant of the resulted matrix (A).
