ADVANTAGE :
? A conventional UPFC system is a combination of a STATCOM and SSSC, which share a DC link capacitor, and comprises two transformers and two power converters, which are bulky and expensive.
? Consequently, although their performance is outstanding, the use of conventional UPFCs has been limited because of these shortcomings.
? Therefore, the use of conventional UPFCs has been limited, although their performance is outstanding. Consequently, the demand for a smaller, lower-cost topology has increased.
? By synthesizing an appropriate injection voltage, the performance of the power flow control could be verified.
? The voltage of the DC link was controlled well according to the reference of 150 V.
