In order to absorb large-scale clean energy for power grid, the use of energy storage technology is paid more and more attention. However, most of the current researches are focused on a single kind of energy storage forms, and few are involved in the joint use of multiple energy storage devices.
To address the frequency regulation challenges caused by large amount integration of renewable energy sources, utilization of flywheel energy storage for its advantages mentioned above combined with various power plants to participate in frequency regulation are proposed [87]. Energy storage allocation methods are summarized in
