Re: Asymmetrical transmission line limits

[Carlos E Murillo-Sanchez]

You can get an approximation to this on the active power flow using the angular difference limits in specified in the branch table.  Columns ANGMAX and ANGMIN tell the opf solver to implement ANGMIN  <=  \theta_f - \theta_t  <=  ANGMAX Carlos.

For a transmission line between two buses, A and B, I was hoping to set the transmission limit from A to B as some value x, and the transmission limit from B to A is some different value y (i.e. x ~= y).   As far as I can tell when a branch is declared in ‘mpc.branch’, it is always bidirectional and the limits imposed are the same regardless of the direction of power flow.   Does anyone know how I could possibly set asymmetrical limits on the transmission lines? If anyone could provide some insight into this problem it would be greatly appreciated.   Danisz Stalinski
