Analysis of energy consumption for a building using wind and solar energy sources

The Renewable Energy Sources (RES) are more and more mixed and exploited in urban site buildings. The main goal of this paper is to understand the nonlinear dynamics of the energy consumption of a building in real time. This way will lead us to predict, in real time, the energy needed depending on the weather. The knowledge of good models is essential to design efficient predictors. This paper develops a simulation model for energy consumption and production of a house equipped with a multiple RE sources systems (PV, Thermal, Wind and storage system). Storage using batteries is also considered. This forward prediction is useful for the Energy Management System that will control the energy sources for the power production answering the demand. After the analysis of house consumption for thermal heating and the classical loads, we consider the modeling of the energy source. This analysis will be used to try new real time management approaches which decide on the optimum connection of the RES to be used for the power demands at each time instant depending on the weather conditions and the Hybrid RES operating states.
