EE/Econ 458 LPOPF

EE/Econ 458 LPOPF. J. McCalley. The linear program optimal power flow is functionally equivalent to the SCED (but not to the SC-SCED). The main difference is that LPOPF uses DC power flow equations whereas SCED uses linear sensitivities (generation shift factors).

Why Sensitivity Analysis

Why Sensitivity Analysis. So far: find an optimium solution given certain constant parameters (costs, demand, etc) How well do we know these parameters? Usually not very accurately - rough estimates Do our results remain valid? If the parameters change ...
