To date, various energy storage technologies have been developed, including pumped storage hydropower, compressed air, flywheels, batteries, fuel cells, electrochemical capacitors (ECs), traditional capacitors, and so on (Figure 1 C). 5 Among them, pumped storage hydropower and compressed air currently dominate global …
Traditional hierarchical control of the microgrid does not consider the energy storage status of a distributed hybrid energy storage system. This leads to the inconsistency of the remaining capacity of the energy storage system in the process of system operation, which is not conducive to the safe and stable operation of the system. …
This paper proposes a dynamic state-of-charge (SOC) balance control strategy for the modular super capacitor energy storage system (ESS). The strategy takes SOC information as the droop variable and introduces the SOC of each module into its independent current closed loop by inverse droop control, so that the system can adjust …
