Analytical resolution of the electrical four-parameters model of a photovoltaic module using small perturbation around the operating point

Toledo, F.J.; Blanes, José M.; Garrigós, Ausiàs; … - In: Renewable Energy 43 (2012) C, pp. 83-89

In this paper, a new real-time curve fitting method for photovoltaic (PV) modules is presented. The method solves the four-parameters photovoltaic cell model without scanning the entire I–V curve, without sensing irradiance or temperature and with no need of any manufacturer data. Only six...

A multi-agent system for energy management of distributed power sources

Lagorse, Jeremy; Paire, Damien; Miraoui, Abdellatif - In: Renewable Energy 35 (2010) 1, pp. 174-182

The field of energy management is an area increasingly studied. However, most solutions are based on centralized systems and barely fulfil criterion like fault tolerance or adaptability. Also, these systems are often difficult to design because of the “top–down” approach used: the designer...

Characterization of the insulation and leakage currents of PV generators: Relevance for human safety

Hernández, J.C.; Vidal, P.G.; Medina, A. - In: Renewable Energy 35 (2010) 3, pp. 593-601

Protection against electric shock in photovoltaic generators (PVGs) with active protective measures requires an in-depth knowledge of the electrical behaviour of PVG insulation and PVG response under operating conditions with insulation faults. On the one hand, this knowledge can be obtained...
