“…Tests on batteries have then been performed, including initial characterization, calculation of the energy capacities and efficiency at different power rates, impact of the different environmental and internal battery temperatures, identification and tuning of the state of energy parameters. Based on measured data of local load demand [4], wind speed [1] and solar radiation [2,3], preliminary forecasting models have been developed for Tilos island, principally with the use of Artificial Neural Networks.…”
