This question is based on our three-node network where all resistances are equal. Generators are located at nodes 1 and 2, while the customer is located at node 3.
Power flows through the network are:
F(1,3) = 44 MW
F(2,3) = 56 MW
F(1,2) = -12 MW (i.e., 12 MW from node 2 to node 1)
The transmission limit on Line (1,2) is 10 MW in either direction, so the line is overloaded by 2 MW. Assume that lines (2,3) and (1,3) can carry a very large amount of power, so that they will never be congested. Calculate the adjustment for Generator 1 that relieves the transmission congestion on line (1,2).
If you find that Generator 1 should increase output to relieve the congestion, then enter your response as a positive number. If you find that Generator 1 should decrease output to relieve the congestion, then enter your response as a negative number.
