CERVERA, Alfredo  and  CAICEDO-DELGADO, Gladys. Expert system for regulating voltage in Distribution Network. Ing. compet. [online]. 2015, vol.17, n.1, pp.23-34. ISSN 0123-3033.

This paper presents an application based on the operational experience of 22 years to regulate voltage in the distribution system of Pacific Energy Company (EPSA). Therefore, an expert system (SE) based on heuristic rules used by operators and have been experimentally tested is presented. The maneuvers executed reset voltage levels in 95% of the nodes, do not exceed the thermal limits of the various elements of the system, or system operating limits. This SE developed in MATLAB 8 heuristic rules used to identify the type of regulation problem and to define the resources to offset the reactive to improve voltage levels. Validation was performed on the model of SEP implemented in DIgSILENT software. The contribution of this work is that it is integrated into the solution, regulatory criteria considering the joint operation of transmission and distribution system, which is closer to reality
