Modelling and control of a hybrid renewable energy system to supply demand of a green-building

The Proceedings of the International Congress on International Environmental Modelling and Software (iEMSs 2010) are available here: http://www.iemss.org/iemss2010/proceedings.htmlInternational audienceRenewable energy sources are an "indigenous" environmental option, economically competitive with conventional power generation where good wind and solar resources are available. Hybrid plants can help in improving the economic and environmental sustainability of renewable energy systems to fulfil the energy demand. The aim of this paper is to present the architecture of a Decision Support System (DSS) that can be used for the optimal energy management at a local scale through the integration of different renewable energy sources. The integrated model representing a hybrid energy generation system connected to the grid is developed. It consists of PV and solar thermal modules, wind turbine and biomass plant. Moreover, a framework is presented for the optimization of the different ways to ensure the electrical and thermal energy demand of the microgrid as well as the water demand, with specific reference to two main cases for the real time energy optimal control: the presence/absence of a storage system. Finally, the optimization model has been applied to a case study
