Abstract
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.
