Ordered charge-discharge and optimal scheduling of energy storage battery
Abstract
This paper presents a method to coordinate the discharge depth and charge-discharge times. The method is based on the operation strategy of the partial batteries used alternatively. Under certain premise, the concept of ordered charge-discharge is put forward, and the rules of ordered charge-discharge are explained in this paper. According to the relationship between the number of cycle times and the discharge depth, the number of the corresponding power distribution cell is obtained under maximum lifetime. By considering the balance of battery charge-discharge and state of charge, a power allocation strategy based on ordered charge-discharge is proposed, and the operation cost of the battery energy storage system is used as the evaluation index of the optimal scheduling. It is proved that the battery energy storage system under the ordered charge-discharge is more economical than the power sharing system, which shows the advantage of the battery charge-discharge.
