CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper a distributed-computing technique to extract photovoltaic module parameters is presented. The proposed procedure is based on a particle swarm optimization (PSO) strategy that exploits interlacing of the experimental data in order to decrease the computational load, and parallel computing of different and independent runs to collect a large amount of data in order to save computational time. The results show that the choice of the search range width and the rules to accept/refuse possible solutions strongly influences the parameter extraction and involves exploiting further statistical analysis to control the statistical instability typical of numerical data fitting algorithms.
