Integration of energy storage based on batteries and supercapacitors in smart grids: which technologies to employ and what benefits to expect?

The green energy revolution led to an increasing deployment of intermittent renewable energy generation. Renewable sources will account for almost half of the European power generation mix by 2030. To ensure the stability and reliability of smart grids, energy storage is usually adopted to balance the ‘ebb and flow’ between generation and consumption. Battery technologies have improved along the energy transition and their lower costs have confirmed their wide use in modern grids to improve their dependability.

Hybrid energy storage systems combining batteries and supercapacitors have proven their effectiveness in such applications. Nevertheless, it is necessary to monitor in real time the state of health of such storage devices to predict their failure before it occurs. Li-Ion batteries are interesting candidates for stationary applications because of their good reliability and lifetime compared to other technologies, which are financially still more competitive. It then interesting to study the behavior of different kind of batteries, under the same load profile for a smart grid, to estimate the profitability and the amortized cost of each technology over lifetime.
