Question

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) = 44.5 MW

F(2,3) = 55.5 MW

F(1,2) = -11 MW (i.e., 11 MW from node 2 to node 1)

Line (2,3) is overloaded by 1.5 MW. Assume that lines (1,3) and (1,2) 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 (2,3).

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.
