摘　　要：针对当前电网公司逾龄资产体系较大且逾龄设备管理相对薄弱的现状,提出一种考虑输配电价影响的逾龄资产退役优化决策方法。首先,根据输配电价改革的政策方案,建立省级电网在不同电压等级下的输配电价核算模型;其次,以全投资周期收益最高为优化目标、以逾龄资产退役时间和退役规模为决策变量,建立逾龄资产退役规划模型,并通过滚动优化和反馈矫正过程,确保在每个阶段逾龄资产退役规模能够跟踪期望值,以在满足系统可靠性的前提下尽可能使电网公司效益最大化;最后,以某省110 kV电压等级电网为例验证了模型的有效性以及在提高投资效率方面的优越性。Given the prevalent issue of aging assets within power grid companies and the subpar management of aging equipment,a decision-making approach was introduced for optimizing the decommissioning of aging assets,taking into account the influence of transmission and distribution tariffs.Firstly,in accordance with the policy framework for reforming transmission and distribution tariffs,an accounting model for transmission and distribution tariffs for provincial power grids operating at varying voltage levels was developed.Secondly,the decommissioning planning model for over-age assets was established with the optimization objective of achieving the highest return throughout the investment cycle.The decision variables of time and scale for decommissioning were utilized in this model.Through a process of rolling optimization and feedback correction,the model ensured that the scale of decommissioning for over-age assets in each stage aligns with the desired value,thereby meeting the premise of system reliability.Finally,the efficacy of the model and its ability to enhance investment efficiency were demonstrated through the examination of the 110 kV voltage level grid in a specific province.
