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：為克服目前全壽命周期成本(life cycle cost，LCC)技術(shù)的應(yīng)用局限于設(shè)備運行或維護階段的不足，針對輸電網(wǎng)整體建立一個3維LCC層級模型，，包括時間維度、元件維度和費用維度。費用維度進一步分解為設(shè)備級、系統(tǒng)級、外部環(huán)境成本。研究了以可靠性為中心的維護手段的應(yīng)用對維護成本的影響，利用電量不足期望值計算故障成本。在此基礎(chǔ)上，對風(fēng)電等4種不確定因素進行建模，建立以LCC成本最小和切負(fù)荷量最小為多目標(biāo)的輸電網(wǎng)機會約束規(guī)劃模型。采用正態(tài)邊界交點算法聯(lián)合改進小生境遺傳算法，對模型有效求解。最后，分別對18節(jié)點系統(tǒng)和77節(jié)點系統(tǒng)進行算例分析。研究結(jié)果給出了帕累托解集及推薦的最優(yōu)規(guī)劃方案；此外，LCC費用分解圖表明了各費用的比重和影響，有利于指導(dǎo)未來資產(chǎn)管理。

電網(wǎng)規(guī)劃中“經(jīng)濟性”的要求不僅僅是短期投資或成本最小，而是著眼于長期時間段內(nèi)包括投資在內(nèi)的所有成本最小、利潤最大。全壽命周期成本(life cycle cost，LCC)是在產(chǎn)品壽命周期或其預(yù)期的有效壽命期內(nèi)，產(chǎn)品設(shè)計、研究和研制、投資、使用、維修及產(chǎn)品保障中發(fā)生的或可能發(fā)生的一切直接的、間接的、派生的或非派生的所有費用的總和。文獻[1-3]對產(chǎn)品的LCC分析進行了較為完善的綜述。最近幾年，LCC技術(shù)逐漸向電力系統(tǒng)推廣應(yīng)用。文獻[4]導(dǎo)出了4種不同諧振電路的LCC公式，并進行了成本最優(yōu)設(shè)計。文獻[5]利用一個時間連續(xù)的
