What are the models of clockwork energy storage devices
In Assumption 2.3, considering the energy loss associated with the storage and extraction of energy in ESDs, if there is a braking train nearby, the accelerating train will prioritize the immediate use of regenerative energy. Such an assumption is widely used in literature on metro storage devices (Liu et al., 2018, Wang et al., 2023).
