    This paper presents a new approach using fuzzy set theory for
    voltage and reactive power control of power systems. The purpose is to
    find a solution which takes both voltage security enhancement and loss
    reduction into account for an electric power system. The approach
    translates violation level of buses voltage and controlling ability of
    controlling devices into fuzzy set notations using a linearized model. A
    feasible solution set which achieves voltage improvement is first
    attained using the max-min operation of fuzzy sets, the final solution
    which takes power loss reduction into account is then determined
    employing the min-operation on the feasible solution set previously
    obtained. A modified IEEE 30-bus test system is used to demonstrate the
    application of the proposed approach. Simulation results show that the
    approach is efficient, simple, and straightforward
