This paper targets the development of hybrid energy storage systems (ESS), based on the batteries-supercapacitors blending. In particular, we will develop two methodologies for the combined sizing/energy management of hybrid ESS. The first method assumes that the division of power between the sources is performed through low/high pass filters, which

It did however add that the energy storage portion of the system will utilise both "low speed flywheels and containerised lithium-ion batteries". "This initiative will also provide a much faster, cost effective and environmentally friendly spinning reserve (or back-up) as an alternative to traditional generation spinning reserve," the statement added.
