Joint Optimal Replacement and Spare Part Provisioning for Smart Meter

Electric power enterprises are developing towards the digital, information and intelligent directions. It is essential to improve the reliability and availability of smart meter to ensure uninterrupted supply of electricity and accurate power measurement as it is a key component of smart grid operation. The sufficient spare parts inventory of smart meter is the basic guarantee of the immediately installing and replacement. This paper established a smart meter inventory demand forecasting model on the basis of analyzing its fault characteristic and installing requirements. A joint optimization decision model of preventive replacement as well as spare parts inventory policy is developed to obtain optimal management policy with a minimum long-term average operation cost for electric system.
