Optimal preventive control actions using multi-objective fuzzy linear programming technique

This paper presents a proposed procedure depends on the multi-objective fuzzy linear programming (MFLP) technique to obtain the optimal preventive control actions, for power generation and transmission line flows, to overcome any emergency conditions. The proposed procedure is very significant to eliminate violation constraints and to give an optimal preventive action for multi-operating conditions. The proposed multi-objective functions are: minimizing the generation cost function, maximizing the generation reserve at certain generator, maximizing the generation reserve for all generation system and maximizing the preventive action for one or more critical transmission line. Numerical examples are presented in order to show that the proposed MFLP technique achieves a feasible economical cost in addition to the maximal preventive control actions for power systems.
