VASCHETTI, Jorge C; MAGNAGO, Fernando  y  SAUCHELLI, Víctor H. Automatic Voltage Control in Electrical Power System based on Expert Systems. Inf. tecnol. [online]. 2012, vol.23, n.5, pp. 69-84. ISSN 0718-0764.  doi: 10.4067/S0718-07642012000500008.

This paper presents the design of an expert controller applied to voltage level control in a power system . The use of pilot node concept allows to keep stable the list of controllers against topological changes in the network . To achieve the optimal voltage profile, the Alberta Electric System Operator regulations are used. The controller validation is performed by simulating a case library and the solution is compared with results provided by an optimal power flow and a genetic based algorithm . The main advantage of the propose model is the unified treatment of the voltage profile and the reactive dispatch without the need of a two-step algorithm . The proposed controller is suitable for online real -time applications and it is flexible when dealing with problems that present a complex analytical formulation.
