【摘要】：智能電網(wǎng)是世界電力系統(tǒng)發(fā)展變革的最新趨勢,不僅影響到電力行業(yè)本身,而且通過前向和后向關聯(lián)影響到國民經(jīng)濟的各個方面。因此,智能電網(wǎng)的建設不僅需要解決技術層面的具體實施難題,還需要從政策機制、系統(tǒng)規(guī)劃、實施效果評估以及經(jīng)濟社會效益等宏觀管理層面進行分析,然而目前關于智能電網(wǎng)宏觀管理層面的研究相對較少。在這樣的背景下,本文圍繞智能電網(wǎng)發(fā)展過程中管理層面面臨的發(fā)展評估、效益測評以及系統(tǒng)規(guī)劃等關鍵問題展開研究,具體工作主要體現(xiàn)在以下幾個方面： 1)構建能夠同時評估智能電網(wǎng)發(fā)展水平和效果影響的智能電網(wǎng)綜合評估指標體系,并基于模糊層次分析法提出智能電網(wǎng)的綜合評估流程。其中,發(fā)展水平指標體系反映電力系統(tǒng)發(fā)電、輸電、變電、配電、用電和調度6個環(huán)節(jié)的智能電網(wǎng)關鍵技術建設與發(fā)展程度,而效果影響指標體系反映智能電網(wǎng)給發(fā)電公司、電網(wǎng)公司、電力用戶和國家社會等利益相關者帶來的影響和效益。 2)運用資源經(jīng)濟學中的“壓力-狀態(tài)-響應”邏輯框架,構建智能電網(wǎng)社會效益測評體系。首先對智能電網(wǎng)社會效益的產(chǎn)生機理進行系統(tǒng)分析,即將智能電網(wǎng)的各項關鍵技術視作壓力,以其引起的電力系統(tǒng)整體運營運行的性能及效率提高程度看作過渡狀態(tài),然后根據(jù)變量之間的因果邏輯關系建立技術指標集和狀態(tài)測評模型,最后在此基礎上形成智能電網(wǎng)社會效益測評體系。 3)基于博弈論的方法構建能夠兼顧可再生能源發(fā)電公司決策影響與輸電投資經(jīng)濟性的輸電系統(tǒng)兩層規(guī)劃模型。首先運用博弈論中的Stackelberg動態(tài)博弈模型對智能電網(wǎng)環(huán)境下的輸電系統(tǒng)規(guī)劃過程進行分析,然后將電網(wǎng)公司與可再生能源發(fā)電公司分別視作博弈過程中的領導者與追隨者,接著構建相應的輸電系統(tǒng)兩層規(guī)劃模型。 最后對論文中所做的研究進行簡要總結,并指出了該領域有待進一步深入研究的問題。
[Abstract]:Smart grid is the latest trend of power system development and transformation in the world. It not only affects the power industry itself, but also affects all aspects of the national economy through forward and backward correlation. Therefore, the construction of smart grid not only needs to solve the specific implementation problems at the technical level, but also needs to be analyzed from the macro management level, such as policy mechanism, system planning, implementation effect evaluation and economic and social benefits. However, there are few researches on the macro management of smart grid. In this context, this paper focuses on the development evaluation, benefit evaluation, system planning and other key issues in the development of smart grid. The specific work is mainly reflected in the following aspects: 1) constructing a comprehensive evaluation index system of smart grid, which can assess the development level and effect of smart grid simultaneously. Based on fuzzy analytic hierarchy process (FAHP), a comprehensive evaluation process of smart grid is proposed. Among them, the development level index system reflects the key technology construction and development degree of smart grid in power system, such as power generation, transmission, substation, distribution, power consumption and dispatch, while the effect impact index system reflects the smart grid power generation company. The influence and benefit of power grid company, power user and national society. 2) using the "pressure-state-response" logic framework in resource economics, the social benefit evaluation system of smart grid is constructed. Firstly, the mechanism of social benefits of smart grid is systematically analyzed. The key technologies of smart grid are regarded as pressure, and the performance and efficiency improvement of power system is regarded as the transition state. Then, according to the causal logic relationship between variables, the set of technical indicators and the state evaluation model are established. Finally, the social benefit evaluation system of smart grid is formed. 3) based on game theory, a two-layer planning model of transmission system is constructed, which can take into account the influence of renewable energy generation company's decision and the economy of transmission investment. Firstly, the Stackelberg dynamic game model in game theory is used to analyze the transmission system planning process in the smart grid environment, and then grid companies and renewable energy generation companies are regarded as leaders and followers in the game process. Then the corresponding two-tier programming model of transmission system is constructed. Finally, the research in this paper is summarized briefly, and the problems in this field are pointed out.
