The desired features of an SPFC are as follows:

 High reliability with the lowest number of components used

 Impedance control feature using a Shunt–Series configuration

 Lowest installation cost

 Lowest operating cost with minimum maintenance and losses

 Practically relocatable when the system needs change

 Free from component obsolescence for at least three decades, and

 Interoperability so that components from various suppliers can be used, resulting in a global manufacturing standard, ease of maintenance, and ultimately lower cost to consumers.

To meet the above‐mentioned functional requirements, thyristor‐based SVC and transformer/LTCs‐based ST may be a suitable solution as shown in Figure 1-37. Since the proposed solution is based on functional requirements and the lowest cost, it is considered to be an SPFC.
