IoT-oriented management of distributed energy storage for the primary frequency control

The paper describes the experimental activities developed in the IoT Lab of Politecnico di Milano, focused on the use of energy storage systems for the primary frequency control. The IoT Lab is a multi-departmental Lab devoted to design and test experimentally innovative IoT algorithms and TLC techniques for smart user applications. In the paper, an approach based on the Fast Fourier Transform (FFT) is proposed in order to elaborate the electric grid frequency signal and to define a "standard" frequency oscillation, suitable to represent the Italian scenario. The results obtained are exploited to measure a "standard" performance of an electrochemical energy storage system in the provision of the primary frequency control service.
