Hello Ray, I read section 7.5.3 of the manual about *DC transmission lines*, but I still have some questions in what regards simple *powerflow*:
1. As I understand it, the implementation will place dummy generators at each end. Are those buses then switched to PV type, taking the voltage setpoints from VF, VT in mpc.dcline? Are the MVAR limits QMINF, QMAXF, QMINT, QMAXT used in the outer loop when enforcing limits? 2. What happens to the dummy gen on the from side, which has negative P? I mean, I also read that dispatchable loads are implemented as generators with negative injection, but that MATPOWER *automatically* keeps their P/Q ratio fixed at the initially specified value. Does this affect all generators with negative P? Does this only happen in OPF? 3. Does toggle_dcline(mpc, 'on') have to be used when computing simple powerflows too? Regards, -- Jose L.
