The second-use of retired electric vehicle batteries can effectively improve the utilization rate of resources and reduce of resource utilization. In the active distribution network planning

firstly

the charging and discharging depth of the electric vehicle battery is considered

the life attenuation is calculated

and the safety margin of the second-use is determined. After the time-sharing price policy being taken into account

the compensation cost of different types of interruptible load is calculated

and the demand-side response policy is introduced to realize the joint planning with the energy storage system. After the whole life cycle cost and line loss cost during the operation of energy storage system being taken into account

the planning goal is further revised

and the location and volume of the energy storage system are realized. The results show that the use of electric vehicle battery ladder has the merits of cost. The reasonable demand side response is also effective to reduce the planning cost of energy storage system

and effectively improve the economic benefits of active distribution network and safe and stable operation.
