Simulation Results from a Kinetic-Electrochemical Energy Storage Model for Network Frequency Regulation

The aim of this paper is to summarize the simulation results obtained by applying a suitable power control to a hybrid storage system electrical model consisting of batteries and a flywheel. The focus of this research is to investigate whether, by controlling the power shared between the batteries and the flywheel, it is possible to effectively counter the battery aging during the grid frequency regulation service. By exploiting experimental aging tests performed on a lithium-manganese oxide battery module, an electrical battery model which takes into account the battery aging has been developed and joined to a flywheel model in Simulink environment. Hence, simulation tests have been carried out in order to investigate if the flywheel system can be an effective solution to tackle the aging of the batteries.
