Chaveamento automático para controle de transferência de fontes e cargas em um sistema fotovoltaico híbrido.

Abstract

Actually, there exist many possibilities for local energy generation to complement or reduce the consumer dependence on the electricity grid of the power utility. There exist generating systems capable of to store the surplus in battery banks and to inject into the utility network for future receipt of credits in the energy bill. Aiming to promote better management of such systems to maximize the use of locally generated energy, an intelligent system based on the availability of energy can be added to control, the instants in which the different sources will supply the loads, thus bringing a greater autonomy over the system and a consequentely improving the local generation. This work propose a design of an automatic switching to control the transfer of sources and loads in a hybrid photovoltaic system, using computational simulations in Simulink® / Matlab® environment, to verify the dynamic response of the system to the switching and the CADeSIMU® software to design the power and control circuit that will act in the switching of the source and load transfer switches.
