Deciding optimal location for placing FACTS devices [UPFC, IPQC, DPFC] using Bang-Bang control technique

There are many problems arising in the electrical networks. In that, voltage fluctuation and power loss reduction becomes a major drawback in the electrical power supply system. Hence it is necessary to enhance the system power flow by placing suitable facts devices. The placement of FACTS devices in suitable location can lead to control the flow of current and maintain bus voltages in desired level and reduce the losses. The facts devices like Upfc, Ipqc, Dpfc are compared with each other and the higher efficiency converter is identified. Finally, the location for better efficiency is traced out. Back-to-back connection between the shunt and series converters is given for the control capability of UPFC, which allows the active power to freely exchange. UPFC has a DC link whereas DPFC does not have any DC link. It is connected directly to the transmission line to control the hysteresis loss. Optimal location and better efficiency of UPFC, IPQC and DPFC are found out and the devices are placed at the exact location. This project presents one of the BangBang Controller to seek the optimal location of FACTS devices in a power system Proposed algorithm is tested on IEEE 14 bus power system for optimal location of multi-type FACTS devices and the results are presented.
