Compared with the traditional control strategy, the proposed control strategy can effectively balance the SOH and SOC of each energy storage unit and keeps the system's overall capacity for a longer period.
Managing storage state-of-charge (SoC) is critical for en-ergy storage participants. The storage opportunity cost depends on SoC, and various storage operation factors, including degradation rates and efficiencies, depend on power rating and SoC –.
In the SoC-independent storage model, we use constant parameters assume the charge/discharge power rating of 0.25 MW (normalized according to 4-hour energy storage with 1 MWh capacity), one-way charge/discharge efficiency of 90%, and marginal discharge cost of $20/MWh for all seg-ments.
SOH equalisation for energy storage systems is also a popular research point at present, the control of SOH equalisation in energy storage systems is mainly divided into SOH equalisation between individual batteries and SOH equalisation between energy storage units .
Injected active power of both battery energy storage systems (BESSs) in case III. This protective measure prevents overdischarge, preserving the battery’s operational integrity and longevity. It is worth noting that this lower limit depends on the battery technology, and hence, can be easily adjusted in the proposed control scheme.
If the system is operated according to the traditional equal sharing control strategy, the simulation results are shown in Fig. 7 d, where the energy storage system has storage units whose health state drops to 80% after 3556 h of operation, which in turn reduces the capacity of the whole system.
