This paper proposes a msulti-stage procedure to overcome the effects of different emergency conditions using multi-objective fuzzy linear programming (MFLP) technique. Comparison studies between two linear fuzzy models, triangular and trapezoidal models, are performed to obtain the best membership model for modeling power system variables. Also, this paper presents multi-modes of fired fuzzy linguistic rules inside the security regions for different constrained power dispatch (CPD) controller centers. The optimal preventive control actions from power generation and transmission line power flows are prepared using MFLP technique. This preparation helps the system operator to face any emergency conditions without making a corrective control action, while, all system constraints are kept within their permissible limits. The results show the capability of the proposed procedure to remove different emergency condition effects.
