Static Inter-Phase Power Controller (SIPC) modeling for load flow and short circuit studies

► A novel topology for IPC, called SIPC, is introduced. ► The steady state studies have shown that SIPC has all capabilities of IPC. ► In addition, it can reset the control error to zero. ► The more significant result is that It develops the IPC power control domain efficiently. ► As a result, SIPC has the merits of IPC and UPFC simultaneously. In this paper, the topology for Inter-Phase Power Controller (IPC), called the Static Inter-Phase Power Controller (SIPC), is discussed. In this topology, the Phase Shifting Transformers (PSTs) of IPC have been replaced by Voltage Source Converters (VSCs). SIPC is modeled and studied under different operating conditions. It is shown that SIPC not only has all capabilities of conventional IPC; such as power flow control, fault current limitation and voltage isolation but also resets the control error to zero. In addition, SIPC increases the variations range of control variables of IPC, namely the phase angles (φ1,φ2) and as a result, the range of variations of active and reactive powers.
