![Given two thermal generating units with the following polynomial cost functions:
Coal Fired: F₁ (P₁) = 50+2P₁ +0.02P2$/h; 40MW < P < 200MW
Gas Fired: VF₂(P₂) = 50+ P₂ +0.04P2$/h; 60MW <P₂ <250MW V
In an economic dispatch, if the load is reduced to 180 MW, which case is cheaper?
Select one:
O a. Unit 1 is OFF, and P₂ = 180 MW
O b.
P₁ = 111.67 MW, P₂ = 68.33 MW.
C.
P₁ = 180 MW, and unit 2 is OFF.
O d. None of these
O e.F - 120 MW, P₂ = 60 MW.
O f.P₁ = 114 MW, P₂ = 66 MW.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd99b6acb-3c56-46a2-8aaf-762988209417%2Fe624a101-c4fe-461e-a12d-065cc0645160%2F2iqhqa8_processed.jpeg&w=3840&q=75)
