【摘要】：配電設(shè)備的檢修是保證供電可靠性和經(jīng)濟(jì)性的必要措施,檢修計(jì)劃的合理與否,不僅僅影響著供電企業(yè)的和用戶的利益,更對社會有著深遠(yuǎn)的影響。隨著技術(shù)的發(fā)展,配電設(shè)備的檢修會遇到更多新的挑戰(zhàn),當(dāng)前階段主要挑戰(zhàn)有兩個(gè)方面,其一為狀態(tài)檢修技術(shù)的發(fā)展,要求檢修計(jì)劃的制定需要從設(shè)備健康狀態(tài)出發(fā),統(tǒng)籌檢修設(shè)備個(gè)體與配電網(wǎng)整體運(yùn)行的利益;另一個(gè)挑戰(zhàn)為分布式電源技術(shù)的發(fā)展,配電網(wǎng)中越來越多地接入分布式電源,其出力不確定性的特點(diǎn),給檢修工作帶來了巨大挑戰(zhàn),最為突出的一點(diǎn)體現(xiàn)在負(fù)荷轉(zhuǎn)移方案的可靠性上。在總結(jié)配電網(wǎng)狀態(tài)檢修和考慮分布式電源出力不確定性的負(fù)荷轉(zhuǎn)移已有研究成果基礎(chǔ)上,本文針對上述兩個(gè)問題,分別進(jìn)行了矛盾關(guān)系分析,梳理出矛盾變量,構(gòu)建了基于博弈理論的負(fù)荷轉(zhuǎn)移模型和狀態(tài)檢修決策模型,主要研究內(nèi)容如下:(1)經(jīng)過對分布式電源出力的觀察與總結(jié),得到分布式電源出力不確定性的特征,在分布式電源出力不確定性的基礎(chǔ)上,分析不確定性對配電網(wǎng)負(fù)荷轉(zhuǎn)移的影響。分布式電源出力的增大與減小,都會引起配電網(wǎng)運(yùn)行約束的破壞,并且影響經(jīng)濟(jì)性。采用博弈策略來解決考慮分布式電源出力不確定性的配電網(wǎng)負(fù)荷轉(zhuǎn)移問題。將分布式電源出力的不確定性虛化為 大自然‖控制的博弈手段,建立了由決策者與大自然構(gòu)成的兩參與者序貫行動博弈模型。最終通過改進(jìn)博弈樹方法求解所建博弈模型的納什均衡解,得到考慮分布式電源出力不確定性的配電網(wǎng)負(fù)荷轉(zhuǎn)移方案。(2)配電網(wǎng)設(shè)備運(yùn)行狀態(tài)與檢修狀態(tài)的矛盾主要體現(xiàn)在設(shè)備既應(yīng)當(dāng)多安排運(yùn)行以保障配電網(wǎng)運(yùn)行的經(jīng)濟(jì)性,又應(yīng)當(dāng)多安排檢修以保證可靠性。在此矛盾上進(jìn)一步探究配電網(wǎng)狀態(tài)檢修中檢修與運(yùn)行協(xié)調(diào)決策的相關(guān)理論,構(gòu)建了以檢修設(shè)備數(shù)目為核心變量、以檢修總支出最小為目標(biāo)的動態(tài)化檢修過程,并充分考慮分布式電源出力的不確定性。首先提出了基于博弈理論的負(fù)荷轉(zhuǎn)移模型以解決新能源電源出力不確定性問題,再此基礎(chǔ)上提出了基于博弈理論的狀態(tài)檢修模型以解決檢修與運(yùn)行協(xié)調(diào)理論的矛盾性問題,最后將二者統(tǒng)一于含源配電網(wǎng)狀態(tài)檢修的工作中,完成方案的制定。最后給出狀態(tài)檢修決策優(yōu)化模型的的啟發(fā)式求解方法。(3)針對基于博弈方法的負(fù)荷轉(zhuǎn)移模型,采用IEEE33節(jié)點(diǎn)算例進(jìn)行方法有效性驗(yàn)證,并進(jìn)行詳細(xì)的對比驗(yàn)證和魯棒性分析;針對基于博弈方法的配電網(wǎng)檢修決策模型,采用IEEE33節(jié)點(diǎn)算例,給出啟發(fā)式算法的具體求解過程進(jìn)行有效性驗(yàn)證,并與傳統(tǒng)檢修優(yōu)化方法得到的結(jié)果進(jìn)行對比分析,同時(shí)進(jìn)行方案的魯棒性分析。
[Abstract]:The overhaul of the power distribution equipment is the necessary measure to ensure the reliability and economy of power supply. The rationality of the overhaul plan not only affects the interests of the power supply enterprises and the users, but also has a far-reaching influence on the society. With the development of the technology, the maintenance of the power distribution equipment will meet more new challenges, and the main challenges in the current phase are two aspects, one is the development of the state maintenance technology, and the development of the maintenance plan requires the development of the equipment health state. The other challenge is the development of the distributed power supply technology, the more and more access to the distributed power supply in the distribution network, the characteristics of the output uncertainty, and the great challenge to the maintenance work. The most prominent point is the reliability of the load transfer scheme. On the basis of summarizing the existing research results of the distribution network state maintenance and considering the load transfer of the distributed power output uncertainty, this paper analyzes the contradiction between the above two problems, and then sorts out the contradictory variables. The load transfer model and the state maintenance decision model based on the game theory are constructed. The main contents are as follows: (1) After the observation and summarization of the distributed power output, the characteristics of the distributed power output uncertainty are obtained, and on the basis of the uncertainty of the output of the distributed power supply, The influence of uncertainty on load transfer of distribution network is analyzed. The increase and decrease of the distributed power output can cause the operation of the distribution network to be destroyed, and the economy is affected. A game strategy is used to solve the load transfer problem of the distribution network considering the uncertainty of the output of the distributed power supply. The uncertainty of the distributed power output is transformed into the game means of the control of the nature, and a two-participant sequential action game model consisting of the decision maker and the nature is established. And finally, solving the Nash equilibrium solution of the established game model by improving the game tree method, and obtaining a distribution network load transfer scheme which takes into account the uncertainty of the output uncertainty of the distributed power supply. (2) The contradiction between the operation state and the service condition of the distribution network equipment is mainly reflected in the fact that the equipment should be arranged so as to guarantee the economy of the operation of the distribution network, and the maintenance should be arranged more and more to ensure the reliability. In this contradiction, the relevant theory of maintenance and operation coordination decision-making in the state maintenance of distribution network is further explored, and the dynamic maintenance process is constructed based on the number of maintenance equipment as the core variable to minimize the total expenditure, and the uncertainty of the output of the distributed power supply is fully considered. First, a load transfer model based on the game theory is put forward to solve the problem of the uncertainty of the output of the new energy power supply, and then a state maintenance model based on the game theory is put forward to solve the contradiction problem of the theory of maintenance and operation coordination. And finally, the two are unified in the work of the state maintenance of the source distribution network, and the development of the scheme is completed. At last, the heuristic method of state maintenance decision-making optimization model is given. (3) Aiming at the load transfer model based on the game method, the method validity verification is carried out by adopting an IEEE33 node numerical example, and the detailed comparison verification and the robustness analysis are carried out; and the IEEE33 node numerical example is adopted for the power distribution network maintenance decision model based on the game method. In this paper, the effectiveness of the heuristic algorithm is verified and compared with the results obtained by the traditional maintenance and optimization method, and the robust analysis of the scheme is carried out.
