Abstract: Flexible alternating current transmission systems (FACTS) devices have been proposed as an effective solution for controlling power flow and regulating bus voltage in electrical power systems, resulting in an increased transfer capability, low system loss and improved stability. However, to what extent the performance can be highly enhanced depends on location and parameters of these devices. Static synchronous series converter (SSSC) is one of the most promising FACTS devices for power flow control. In this paper, we propose an evolutionary optimisation technique, namely bacteria foraging algorithm (BFA) to select the optimal location and optimal parameters setting of SSSC, which minimises transmission loss, production cost and voltage deviation in power network. Case studies with IEEE-30 bus system are presented to illustrate the applicability of the algorithm.
