Linear/quadratic programming-based optimal power flow using linear power flow and absolute loss approximations

Abstract: This paper presents novel methods to approximate the nonlinear AC optimal power flow (OPF) into tractable linear/quadratic programming (LP/QP) based OPF problems that can be used for power system planning and operation. We derive a linear power flow approximation and consider a convex reformulation of the power losses in the form of absolute value functions. We show four ways how to incorporate this approximation into LP/QP based OPF problems. In a comprehensive case study the usefulness of our OPF methods is … Show more

“…We mainly use the linear power and branch flow approximation presented in [4]. Here, we summarize the main results, for full details see [4]. As an extension, we derive transfer distribution factors (TDFs) for voltage magnitudes (VTDF), angles (θTDF) and active /reactive power branch flows (PTDF) as a function of the nodal active and reactive power.…”
