摘要
智能电表是智能电网运行的关键部件,提高其可靠性和可用度对保证电力的持续不间断供应和准确电能测量至关重要。充足的智能电表库存是其换装与维修的基本保障。本文基于智能电表的故障特性和换装需求分析,建立了智能电表的最优更换与备件库存联合决策模型,并给出了优化方法,以求得可以使系统长期平均运营成本最小的最优更换与备件库存策略。
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 in- ventory 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 in- stalling requirements. A joint optimization decision model of preventive replacement as well as spare parts inven- tory policy is developed to obtain optimal management policy with a minimum long-term average operation cost for electric system.
