Unformatted text preview: er in the problem; ‘N − 1’ just means ‘all-but-one’.) This states that the system can still operate even if any one power line goes out, by re-routing the line powers. The case when line j goes out is called ‘failure contingency j ’; this corresponds to replacing Pjmax with 0. The requirement is that there must exist a contingency power flow vector p(j ) that (j ) satisfies all the constraints above, with pj = 0, using the same given generator powers. (This corresponds to the idea that power flows can be re-routed quickly, but generator power can only be changed more slowly.) The ‘N − 1 reliability constraint’ requires that for each line, there is a contingency power flow vector. The ‘N − 1 reliability constraint’ is (implicitly) a constraint on the generator powers. The questions below concern the specific instance of this problem with data given in rel_pwr_flow_data.m. (Executing this file will also generate a figure showing the network you are optimizating.) Especially for part (b) below, you must explain exactly how you set up the problem as a...
