Control Automático de Voltaje en Sistemas Eléctricos de Potencia basado en Sistemas Expertos

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.
