Research ArticleOpen accessIn the abstractFuzzy Based Energy Management of a Domestic Photovoltaic PanelMaher Chaabene, Mohsen Ben Ammar, Ahmed ElhajjajiThis study introduces a new switching mean giving a real time optimum connection mode of domestic apparatus on either the electrical grid or a photovoltaic panel (PVP) output. A fuzzy algorithm makes the decision which ensures the optimal energy management basing on the PVP generation and apparatus states with respect to energy save criteria. Validation was driven on a 1kW … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,006 accessesView PDF Cite
