An approach to constructing sensitivity indices and fuzzy control of system voltage and reactive power

This paper presents the results of research aimed at improving the efficiency of coordinated online control of system voltage and reactive power on the basis of developing models, methods and a control system, integrating traditional numerical techniques with fuzzy logic technology. An approach associated with experimental design is considered to construct diverse types of sensitivity indices, which serve as the basis for multi-attribute evaluating efficiency of control actions, and, therefore, for forming rules included in knowledge base. An example is presented to show the validity and efficiency of the approach. Questions of rational carrying out procedures of fuzzy logic are discussed.
