Optimal Power Flows with security constraints using Cubic Lattice structured multi agent based PSO algorithm by optimal placement of Multiple TCSCs

This paper puts forward the implementation of Cubic lattice structured multiagent based PSO algorithm (CLSMAPSO) to obtain the optimal power flows by optimally placing TCSC devices. The Thyristor Controlled Series Capacitor (TCSC) is modeled using susceptance model with modifications in the Y bus of the Newton Raphson Algorithm. The constraints related to violation limits, minimization of line overload factor, and line loss are dealt using penalty factor approach. The new multi agent based cubic lattice structured PSO algorithm was considered for optimizing power flows while satisfying all the constraints mentioned above. This algorithm was tested on IEEE۱۴, IEEE ۳۰ and IEEE ۵۷ bus systems to identify the suitable location, its reactance value and firing angle. The results obtained were quite encouraging and will be useful in electrical restructuring.
