Multi agent system driven SSSC for ATC enhancement

This paper presents the performance evaluation of Multi Agent System (MAS) driven SSSC. The concept of ATC enhancement has been proposed with SSSC employing MAS which quickly re-establishes power flow over the existing transmission line with almost real time power control mode. Multi Agent System (MAS) works on soft signalling based distributed technology which is capable of solving complex problems by adding intellectual attributes. Interconnected transmission system line loading has to be maintained within the design limits irrespective of external conditions like heavy loading, and this is possible only if the excess load is shifted from one line to another. The redistribution of loading can be obtained by proper coordination among multiple controllers using agents which monitor, communicate and govern the control of power flow controllers (SSSC) to obtain desired loading under dynamic conditions. This operational mode enhances existing ATC values of other lines in the network. Power flow controllers when used in combination with MAS can be viewed as smart controller. The system has been simulated by modeling the system in Matlab Simulink. The multi-agent system is implemented by using an open source agent building toolkit Java Agent Development framework (JADE). Both Matlab simulation and multi-agent system are connected together via MACSimJX toolbox.
