Estimation of UPFC value using sensitivity analysis

This paper presents an estimation technique to obtain a value of the unified power flow controller (UPFC) using sensitivity analysis. Modelling of the UPFC, inserted in a transmission line, is presented for use in an optimal power flow (OPF). An efficient technique to obtain the first- and second-order sensitivities of the generation cost with respect to UPFC control parameters, are described. A case which shows the limitations of our sensitivity method is also analyzed.
