An analytical solution to the optimal power flow

open access: yes, 2002
This letter presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus system (slack and PV busses). The algebraic equations for the calculation of the Lagrange multipliers and for the minimum losses value are ...

Optimal Power Flow with Voltage-Sensitive Loads in Distribution Networks

open access: yes, 2016
Traditionally, the optimal power flow (OPF) assumes a constant (active and reactive) power load model and thus it neglects the effect of the voltage sensitiveness of power load injections.
