Q2.A) A system consists of two plants connected by a tie and a load is located at plant two. When 100MW are transmitted from plant one a loss of 10MW takes place on the T-line. Determine the generating schedule at both the plant and the power received by the load when for the system is GHC 25 per megawatt-hour and the incremental fuel cost are given by the equation

dF1dP1= 0.031P₁ + 17 GHC/ MWh ; dF2dP2= 0.06P₂ + 19 GHC/MWh

Q2. B) The fuel input to two plants are given by F₁= 0.015P₁² +160P₁+50 ; F₂= 0.015P₂² +160P₂+30

The loss coefficient of the system is given by B₁₁= 0.005, B₁₂=-0.0012, and B₂₂ = 0.002. The load to be met is 200MW, determine the economic operating schedule and the corresponding cost of generation, if i) the transmission line losses are coordinated ii) the losses are located but not coordinated.
