Optimal power flow solution with maximum voltage stability

Abstract EN

This paper presents an Optimal Power Flow (OPF) formulation that is based on multi-objective optimization methodology, which can minimize both of operating costs and losses and it would at same time result in maximizing the distance to voltage collapse.

A “ Maximum Distance to Voltage Collapse ” algorithm, which incorporates constraints on the current operating condition, is firstly presented, while OPF formulations which incorporate voltage stability criteria is secondly presented.

The algorithm built on Matlab-Simulink is tested on an IEEE 6-bus test system using a standard power flow model, where the effect of maximum loading point limits is demonstrated.
