Today there is a high interest to install hybrid systems composed by renewable power plants (RES) coupled to energy storage systems (ESS) on geographical islands with or without interconnection. Such is the case in Corsica, an island system with a small interconnection to Italy. Given the objectives for high RES penetration, Corsica has been a playground for the deployment of new hybrid photovoltaic (PV) plants coupled to li-Ion based ESS. The introduction of this new technology imposed new challenges in management and operation of the ESS to guarantee the performance and profitability of such power plants. In this work, different estimation models were developed to predict the thermal behaviour and State of Charge (SoC) of 5 existing hybrid RES power plants that have a li-ion based storage. These approaches allowed a better understanding of the evolution and degradation the systems experience, insights that were later used to optimise the energy management systems present in each power plant.
