Power traveling a long distance from the generation plant to the end-user leads to deterioration of its quality, and the intensive utilization of power leads to serious issues in the grid resulting in power quality problems. To make the system effective and able to meet modern requirements, flexible AC transmission system (FACTS) devices should be installed into the grid. The interline power flow controller (IPFC) is the latest FACTS device, which compensates for both active and reactive power among multi-line systems. The converters used in the IPFC are crucial as they can be adjusted to regulate the power flow among the lines. This paper proposes a cascaded IPFC with hysteresis and proportional resonant voltage controllers. Some main drawbacks of controllers like steady-state errors and reference tracking of converters can be easily achieved by the PR controller, which makes the system efficient and can be used for a wide range of grid applications. Hysteresis and PR controllers are explained in detail in the following sections. A comparative analysis is carried out among control algorithms to choose the suitable controller which maintains stability in the system.}, type={Article}, title={Stability analysis and efficiency improvement of IPFC using latest PR controller}, URL={http://czasopisma.pan.pl/Content/120522/art08_corr.pdf}, doi={10.24425/aee.2021.137577}, keywords={control algorithms, FACTS devices, interline power flow controller, multilevel inverter}, }
