Abstract

This paper presents an application of optimization techniques incorporating voltage stability constraints. L-index that indicates voltage collapse proximity is adapted into the OPF formulation. This paper shows the impact of incorporation of voltage security constraint into optimal power flow formulation in which the active power dispatch problem is associated with guaranteeing adequate voltage security levels in power systems. It provides the optimal solution both minimizing generation cost and guaranteeing voltage security level. Numerical examples using simple 3-bus system and IEEE 30-bus system are also presented to illustrate the capabilities of the proposed formulation.
