Yes, for a transformer you will typically have an off-nominal taps ratio, i.e. branch(b, TAP) ~= 1 (or 0, which signifies a normal transmission line). Similarly, if you have a phase shift, you will have branch(b, SHIFT) ~= 0.
How the transformer TAP and SHIFT parameters affect the amount of load able to be dispatched depends on the network, so it could go either way. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Apr 16, 2013, at 8:18 AM, Jiashen Teh <[email protected]> wrote: > Dear Dr Ray, > > According to your manual , in section '3.2 Branches' > it is mentioned that: > > 'All transmission lines, transformers and phase shifters are modeled with a > common branch model......' > > Does this mean, if I want to include modelling of transformer at a branch, I > would set the column 9 and 10 of mpc.branch which govern the transformer turn > ratio, N ? > > I notice that for values other than zero for both columns (in a manner to > increase N or reduce N), the network (6 bus) will encounter increase of load > not able to be dispatched.
