基于PSTSO多目标优化储能系统功率分配OA北大核心CSTPCD

To improve the power allocation rationality of a battery energy storage system,a power allocation strategybased on the priority of status tuna swarm optimization(PSTSO)algorithm is proposed. First,three evaluation indica-tors for the power distribution of an energy storage system are formulated. Second,a mathematical model is established for the consistency among the energy storage system's operating cost,the state-of-health(SOH)loss of energy storage unit and the system's state-of-charge(SOC). Finally,the PSTSO algorithm is used for power allocation under the prem-ise of satisfying the system power balance,as well as the upper and lower bounds of SOC. The result of numerical analy-sis shows that the proposed strategy can effectively reduce the number of charges and discharges of the battery cell,re-duce the cell's capacity loss and ensure a good SOC consistency for the energy storage system.
