ABSTRACT: In order to overcome the defect that the applications of life cycle cost (LCC) technology are limited to specific equipment or phase, a three dimensional LCC hierarchy model for entire transmission network was established, which includes time dimension, component dimension and cost dimension. The cost dimension was further divided into device layer, system layer and the cost of externalities. The impact of the reliability centered maintenance (RCM) strategy on the maintenance cost was analyzed. The expected energy not supply (EENS) was used to calculate failure cost. On this basis, four uncertainties such as wind power were simulated, and then the multi-objective chance-constrained transmission expansion planning model was proposed with minimum LCC and minimum load cut. The normal boundary intersection (NBI) algorithm integrated with improved niche genetic method was adopted to solve the model effectively. Finally, case studies were carried out respectively on an 18-bus system and 77-bus system. The results generate distributed Pareto set and recommend the optimal planning scheme. Additionally, the distribution structure of LCC shows the proportion and influence of each cost and can instruct the asset management of power systems in the future.

摘要：为克服目前全寿命周期成本(life cycle cost，LCC)技术的应用局限于设备运行或维护阶段的不足，针对输电网整体建立一个3维LCC层级模型，，包括时间维度、元件维度和费用维度。费用维度进一步分解为设备级、系统级、外部环境成本。研究了以可靠性为中心的维护手段的应用对维护成本的影响，利用电量不足期望值计算故障成本。在此基础上，对风电等4种不确定因素进行建模，建立以LCC成本最小和切负荷量最小为多目标的输电网机会约束规划模型。采用正态边界交点算法联合改进小生境遗传算法，对模型有效求解。最后，分别对18节点系统和77节点系统进行算例分析。研究结果给出了帕累托解集及推荐的最优规划方案；此外，LCC费用分解图表明了各费用的比重和影响，有利于指导未来资产管理。

电网规划中“经济性”的要求不仅仅是短期投资或成本最小，而是着眼于长期时间段内包括投资在内的所有成本最小、利润最大。全寿命周期成本(life cycle cost，LCC)是在产品寿命周期或其预期的有效寿命期内，产品设计、研究和研制、投资、使用、维修及产品保障中发生的或可能发生的一切直接的、间接的、派生的或非派生的所有费用的总和。文献[1-3]对产品的LCC分析进行了较为完善的综述。最近几年，LCC技术逐渐向电力系统推广应用。文献[4]导出了4种不同谐振电路的LCC公式，并进行了成本最优设计。文献[5]利用一个时间连续的
