A power system has two synchronous generators. The governor-turbine characteristics orresponding to the generators are P1 = 50(50 ), P2 = 100(51 ). where f denotes the system frequency in Hz and P1 and P2 are respectively, the power outputs (in MW) of turbines 1 and 2.

Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]. Assertion: Fast decoupled load flow method gives approximate load flow solution because it uses several assumptions. Reason: Accuracy depends on the power mismatch vector tolerance.
The fuel cost functions of two powr plants are Plant P1 : C1 = 0.05 Pg 1 + APg1 + B Plant P2 : C2 = 0.10 Pg 2 + APg2 + 2B Where, Pg1 and Pg2 are the generated powers of two plants, and A and B are the constants.
