Question 5. 15 Points The fuel-cost functions in $/h for two thermal generation stations are given by C1 = 800 + 6.0P1 + 0.004 P12 C2 = 1000 + 6.8P2 + 0.002 P22 where P1 and P2 are in MW. The total power demand is 1300 MW. Neglecting losses, determine the optimal generation of each plant and the incremental cost of power λ ($/MWh).

Question 4. 25 Points A single area consists of two generating units, rated at 400 and 800 MVA, with speed regulation of 4 percent and 5 percent on their respective ratings. The units are operating in parallel, sharing 700 MW. Unit 1 supplies 200 MW and unit 2 supplies 500 MW at 1.0 per unit (60 Hz) frequency. The load is increased by 130 MW. Assume there is no frequency-dependent load, i.e., D = 0. Find the steady-state frequency deviation and the new generation on each unit.

Tom started the process of selecting a new system for the firm and he is weighing all of the various issues that need to be considered and the resources he has at his disposal as he makes this important decision. As Tom prepares to narrow the field in his selection of a new system, he wants a quick refresher on the difference between a request for proposal (RFP) and a request for quotation (RFQ). If he needs a request for proposal (RFP), Simone will write it, and if he needs an RFQ, Marny is responsible for writing that. Which of the following is true?​
