Effect of Detailed Power System Models in Traditional and Voltage Stability Constrained Optimal Power Flow Problems

Detailed generator, exponential load, and static var compensator models are incorporated into both traditional and voltage stability constrained optimal power flow problems to study the effect that the different models have on costs and system loadability. The proposed models are compared to typical models by means of a detailed analysis of the results obtained for two IEEE test systems; interior point methods are used to obtain numerical solutions of the associated optimization problems.
