Fuzzy inference system for integrated VVC in isolated power systems
  This paper presents a fuzzy inference system for integrated volt/var control
(VVC) in distribution substations. The purpose is go forward to automation
distribution applying conservation voltage reduction (CVR) in isolated power
systems where control capabilities are limited. A fuzzy controller has been
designed. Working as an on-line tool, it has been tested under real conditions
and it has managed the operation during a whole day in a distribution
substation. Within the limits of control capabilities of the system, the
controller maintained successfully an acceptable voltage profile, power factor
values over 0,98 and it has ostensibly improved the performance given by an
optimal power flow based automation system. CVR savings during the test are
evaluated and the aim to integrate it in the VVC is presented.
