EPC504 L. - 400 MW L - 550 MW 0+ o to La - 450 MW L - 350 MW Problem 2 Assume that the four areas are centrally dispatched by a pool control center. a. Find the generation and production cost in each area. b. Assume a split-savings pool agreement such that each area exporting receives its increased costs of production plus its proportionate share of 50% of the pool savings. Find the cost per MWh of transfer energy (i.e., "pool energy") and the net production cost of each area. Problem 1 Four areas are interconnected as shown Figure. Each area has a total generation capacity of 700 MW currently on-line. The minimum loading of these units is 140 MW in each area. Area loads for a given hour are as shown in Figure. The transmission lines are each sufficient to transfer any amount of power required. The composite input-output production cost characteristics of each area are as follows: Fl=200 + 2P, +0.005P, ?($/h) F2 = 325 + 3P2 +0.002143P22 ($/h) F3 = 275 + 2.6P3 + 0.003091P32 ($/h) F4 = 190 + 3.1P4 +0.00233P4-($/h) Find the cost of each area if each independently supplies its own load, and the total cost for all four areas. Assume that area 1 engages in two transactions. a. Area 1 buys 190 MW from area 2. b. Area 1 sells 120 MW to area 3. For each of these transactions, the price is based upon a 50-50 split-savings agreement. Find the price of each transaction, the net generation costs for each area including the sum it pays or receives under the split-savings agreement, with the order of the transactions (as given above) being as follows. i. a then b. ii. b then a. In both instances, find the total cost for the four-area pool. I
