Parametrización del Esquema de Disparo de Generación ante Eventos de Sobrefrecuencia en un Sistema Eléctrico Utilizando Técnicas de Optimización

The electrical power systems should, as far as possible, maintain the safety and stability of its operation, therefore, evaluation criteria are established for possible situations and conditions that may cause the system to operate erroneously. One of these conditions occurs at the moment of having frequency variations, which are solved through the operation of generation tripping devices in the case of overfrequency and load shedding devices in the case of low frequency, under the consideration of avoiding a cascade operation of the same, since it could cause an eventual collapse of the frequency of the power system. In this article, the parameterization of a generation tripping scheme is analyzed through the application of Multiobjective Optimization using a Genetic Algorithm, at the moment in which an overfrequency occurs in the system. This scheme was proposed for the 39-bus IEEE Power System of New England implemented in PowerFactory in which a generation tripping strategy is proposed that adapts to the new power flow of the electric system; which implies having less operating costs of the electric system and less energy consumption. The effectiveness of the strategy is simulated and its adaptability is tested.
