Abstract
The authors present a scheme of hybrid optimisation using parallel simulated annealing and a Lagrange multiplier for optimal SVC planning. Aiming for voltage stability enhancement, the proposed scheme is posed as a multiobjective optimisation problem for maximising a fuzzy performance which represents the power system reactive (VAr) margin, system I2R losses and voltage depressions at critical points. To ensure robustness, the paper proposes a four-step procedure for synthesising optimal VAr reinforcement
