Distribution management and optimal supply of reactive power in restructured power systems using PSO Algorithm

By the help of reactive power, different technological index could be improved in strength System. Voltage stability margin, considered as one the important index of strength system security determination. In this way, effects of Economic performance of ISO (Independent System Operator) must be investigated over reactive power dispatch. In reactive power optimal dispatch, usually voltage stability limit in crease per reactive power minimum cost describes as the main goal of this issue on the other hand, different purposes in reactive power. Short - term planning could be expressed as non - liner optimization issue. in this paper, one the newest methods of intelligent search called PSO Algorithm introduced for these models solution could be used that its capability evaluated by applying an Algorithm in optimal supplying of required reactive power for WSCC, 9-Bus System. Responses compared with genetic Algorithm method.
