This paper presents an efficient method based on bus power injection for transmission line compensation. In this method, the load flow solution is first obtained using specified generations and loads. The terminal buses connecting the line to be compensated and the compensation level are identified. The differences of the line flows before and after compensation are injected in or out of the two terminal buses. The proposed method has been successfully used to simulate compensation of transmission line by a series capacitor and then by SSSC.
