| Abstract: | An optimal power-cable maintenance scheme based on stochastic dynamic programming is proposed, which applies the stochastic aging model of power-cable to obtain its failure rate distribution and insulation aging level. The annual maintenance schedules within the planning period are given for optimizing the overall cost, reducing the unexpected power outages due to power-cable fault and improving the operational reliability of power grid. |

| Keywords: | power cable life-cycle cost statistical dynamic programming insulation aging cable opera-tion and maintenance management |
