Modelación dinámica de la oferta-demanda de una micro red-eléctrica

Abstract

In this paper , it propose a dynamic simulation model, in order to prognosticate the supply and demand of electric energy that would have a microgrid, consisting of a house with its own generation through solar PV modules and A micro wind turbine, that’s a hybrid system, whose load is the demand of the house throughout the day.

The prognosis is determined by considering the physical parameters such as climate and proper sizing of the hybrid system. For the subsystem of generation through PV modules, three methods are raised, they indicate amount of radiation that can be obtained on a useful surface, each has different efficiencies and any of the three may be applied to the microgrid study. The generation subsystem through a micro turbine, considering the wind as the main source, that is modeled by the Weibull distribution, which allows us to obtain the probability of having a certain wind speed at a given instant, with it determined the generation capacity

For demand determination is considered the equipment of the house, such as devices are connected with the residents activities, as well devices that have a consumption activity not related to them. With this it will integrate the load curves and daily generation would have the microgrid, which can demonstrate the improvement of the final daily load curve.
