Linear approximations to AC power flow in rectangular coordinates [PDF]
2015 53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2015 This paper explores solutions to linearized powerflow equations with bus-voltage phasors represented in rectangular coordinates. The key idea is to solve for complex-valued perturbations around a nominal voltage profile from a set of linear equations that are obtained by neglecting quadratic terms in the original nonlinear power-flow equations.
