Abstract. This paper presents the effect of posicast controller on mitigation of small signal oscillatory stability. Posicast is adopted as a rule of action which could be taken on any dynamic system. Tuning parameters is calculated by inherent characteristic of the system which also indicates the place that the posicast is needed. Each posicast adheres to its defined mode and shows its effect whenever they start to oscillate and does not have any side effect on normal operation of the system. The New England 39-Bus system has been chosen to evaluate the performance of the controller. Improvement in rotor angle, generators active power, lines active power, buses frequency and stability margin have been observed.
