relationship between balancing units and shared energy storage

What happens if energy storage system is operated according to equal sharing?

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 h of operation, which in turn reduces the capacity of the whole system.

What is a control strategy for energy storage?

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.

How to constrain the capacity power of distributed shared energy storage?

To constrain the capacity power of the distributed shared energy storage, the big-M method is employed by multiplying U e s s, i p o s (t) by a sufficiently large integer M.
