“…The components of the Jacobian array provide the sensitivity between the power flow and the variations in the node voltage. Although both P and Q affect voltage stability to a certain extent, the main interest is the dominant relationship between Q and V Therefore, at each operation point, a continuous P must be maintained, and the voltage stability must be evaluated, taking into account the gradual relationship between Q and V. Based on the previous consideration, the incremental relationship between Q and V is expressed by means of Equation (12), considering that ∆P is equal to 0 [43].…”

This study presents a procedure for placing static var compensators (SVC) in an EPS using the fuzzy c-means clustering technique. For this purpose, the optimal power flow (OPF) is initially quantified to obtain the sensitivity array of the system based on the Jacobian of the system. Then, the attenuation and electrical distance matrices are estimated. Subsequently, the fuzzy c-means clustering algorithm is used with the initially estimated cluster identification criterion to obtain the voltage control areas (VCAs). On the other hand, the criterion of minimizing the installation costs of the SVCs is used in conjunction with the linear voltage stability index (LVSI) for the ideal arrangement of the compensators. This is applied to each VCA created. The technique described is applied to the 14-node and 30-node schemes to check their effectiveness. Additionally, the results obtained are compared with the Power Factory software and with similar studies. Finally, the proposed technique proves to be effective for the creation of VCAs and for the optimal placement of SVC equipment.
