Abstract

The unified power flow controller (UPFC) approach maximizes active power transfer with the least amount of losses by independently controlling both reactive and active power flow. This makes it possible to use individual transmission lines more effectively. The interline power flow controller (IPFC) utilizes the concept of UPFC for economic operation and control, management of multiline transmission systems. In its most basic form, the IPFC consists of many DC to AC converters such as voltage source inverters (VSCs), each of which performs the same purpose as the UPFC: providing series compensation for every line in multiline transmission system. A novel idea for the efficient power flow control management and compensation in multiline transmission system is the IPFC. This research proposed a backup controller for an effective modelling of IPFC in order to reduce low-frequency oscillations using four different damping controller options. The choice of an efficient damping control signal is discussed in this work in order to create a durable IPFC damping controller that can withstand changes in system loads and power supply problems. Using the proposed control approach, it is feasible to acquire both oscillation damping and independent interline power flow regulation. The results obtained in this research was improved the dynamic stability of the system using VSC based IPFC and proposed control strategy.

Keywords: UPFC, IPFC, System Stability, Damping of Oscillations, Reactive Power Compensation.
