• Resumen

  • Environmental, social and economic drawbacks of fossil and nuclear fuels are leading to an increased use of renewable energy sources. The strong tecbnological development ofrenewable-based generation systems during the last years, especially in the case of wind and photovoltaic systems, has !ed to an impressive reduction of production costs and made these technologies competitive with conventional power plants. At present, the main barrier that limits their massive integration into the e!ectrical grid is their reduced manageability due to the intermittent nature of renewab!e resources. Distributed energy storage systems, particularly lithium-ion batteries and supercapacitors, arise as one of the bes! options to provide manageability to these systems and help operate an electrical grid increasingly based and dependen! on renewable power plants.

    This thesis analyses in depth both energy storage technologies, in particular when they operate in renewable generation systems. The main research lines ofthe thesis are: • Analysis ofthe state ofthe art oflithium-ion battery and supercapacitor technologies .

    • Study of the influence of thermodynamic, electrochemical and thermal phenomena on the operation of these storage technologies.

    • Electrochemical and thermal modelling ofboth tecbnologies .

    • Estimation ofthe state of charge and ageing oflithium-ion batteries .

    • Experimental validation of the proposed models under different operating conditions .

    • Development of methodologies for the optima! design and operation of storage systems based on lithium-ion batteries in renewable environments, and irnplementation in photovoltaic power plants
