please .. I would like solve the Question 1 and 2 .

thanks of a lot .

Q1. A generation system has three units with the following cost characteristics as shown below. C1(P) = 100+ 3 P1 + 0.01 P.2 C2(P2) = 250 + 2.5 P2 + 0.005 P22 C3(P3) = 500 + 2 P3 + 0.0025 P32 a) The generation company's own system demand is 950 MW each and if the market price is $5/MWh find Buy - Sell decision for each unit b) If the market price changed to $7/MWh, find Buy - Sell decision for each unit Note: U1, U1, U1 capacities are as follows 1200MW, 1500MW and 1600MW Q2. Following is the arrangement of buy/sell bids received by an energy broker. The four utilities are donated by U1, U2, U3, and U4 with appropriate capabilities for generating and consuming power 150 -U3 Price, S/Ah 04 120 100 -U4 60 -U2 30 -U1- Quantity. W 200 30 50 100 125 Answer the following with respect to the above Figure: a) Determine all the broker transactions, their prices and savings achieved: Transaction from Transaction to Quantity (MW) Transaction price ($/MWh) Savings (S/MWh) b) The total energy cleared (MWh) by the energy brokerage = c) The market clearance price = Q1.
