【摘要】：在全球能源消費需求持續(xù)增長的背景下,資源枯竭與環(huán)境污染的雙重壓力給經(jīng)濟社會發(fā)展帶來了嚴峻的挑戰(zhàn)。近年來,國內(nèi)外對智能電網(wǎng)的建設(shè)趨于成熟,為電力能源的高效利用提供了技術(shù)基礎(chǔ)。然而,隨著可再生能源的廣泛發(fā)展以及電氣化交通網(wǎng)絡(luò)的接入,電力網(wǎng)絡(luò)面臨著前所未有的發(fā)展瓶頸,主要表現(xiàn)在系統(tǒng)的穩(wěn)定性與可靠性受到挑戰(zhàn)。在此背景下,能源互聯(lián)網(wǎng)(Energy Internet)的概念隨之而出,在我國,能源互聯(lián)網(wǎng)依托于傳統(tǒng)骨干電網(wǎng),接入大規(guī)模的可再生能源系統(tǒng)、即插即用電動汽車,并融合了交通網(wǎng)絡(luò)與天然氣網(wǎng)絡(luò)等,是一個具有高度靈活性與實時性的復雜網(wǎng)絡(luò),其可靠性的要求也相對提高。近年來,復雜網(wǎng)絡(luò)理論在復雜系統(tǒng)的研究中有了重大突破�；趶碗s網(wǎng)絡(luò)理論研究電力通信網(wǎng)絡(luò)的可靠性也日漸興起,對于傳統(tǒng)的電網(wǎng)研究方法來說是一個重大的突破;相比較于傳統(tǒng)的電力通信網(wǎng)絡(luò),能源互聯(lián)網(wǎng)的通信網(wǎng)絡(luò)是更復雜的網(wǎng)絡(luò),更適合運用復雜網(wǎng)絡(luò)理論來研究,因此,本文擬將復雜網(wǎng)絡(luò)理論運用在能源互聯(lián)網(wǎng)通信網(wǎng)絡(luò)的可靠性分析中。本文首先研究了復雜網(wǎng)絡(luò)理論的基本概念及其特征參數(shù),然后分析了未來能源互聯(lián)網(wǎng)的基本特征及其通信網(wǎng)絡(luò)所具有的小世界特性與無標度特性。接著,本文給出了一種對可靠性分層分析然后整體評估的可靠性研究方法,來分析能源互聯(lián)網(wǎng)通信網(wǎng)絡(luò)可靠性,其中,對于拓撲結(jié)構(gòu)層可靠性采用了抗毀性、生存性相結(jié)合的方法分析。在此基礎(chǔ)上,本文對所給出的能源互聯(lián)網(wǎng)通信網(wǎng)絡(luò)拓撲結(jié)構(gòu)的模型進行了仿真模擬;并將此網(wǎng)絡(luò)模型與互聯(lián)網(wǎng)AS級拓撲和美國電力通信網(wǎng)絡(luò)拓撲從復雜網(wǎng)絡(luò)層面進行了各項參數(shù)比較,從而得出本文的網(wǎng)絡(luò)模型與互聯(lián)網(wǎng)有若干相似特性,比傳統(tǒng)電力通信網(wǎng)絡(luò)更符合網(wǎng)絡(luò)通信的要求。最后,將本文的能源互聯(lián)網(wǎng)通信模型與某省電力通信網(wǎng)在隨機攻擊與蓄意攻擊兩種形式下,從抗毀性和生存性方面進行了可靠性的分析比較,得出該能源互聯(lián)網(wǎng)通信網(wǎng)絡(luò)模型比該省電力通信網(wǎng)更可靠。
[Abstract]:Under the background of the continuous growth of global energy consumption demand, the dual pressure of resource depletion and environmental pollution has brought severe challenges to the economic and social development. In recent years, the construction of smart grid at home and abroad tends to mature, which provides a technical basis for the efficient use of power energy. However, with the extensive development of renewable energy and the access of electrified transportation network, the power network is facing unprecedented bottleneck of development, which is mainly reflected in the challenges to the stability and reliability of the system. In this context, the concept of energy Internet (Energy Internet) has emerged. In China, the energy Internet relies on the traditional backbone grid, access to large-scale renewable energy systems, plug and play electric vehicles, It is a complex network with high flexibility and real time, which combines transportation network with natural gas network, and its reliability requirements are also improved. In recent years, the theory of complex network has made a great breakthrough in the research of complex systems. The research on the reliability of power communication network based on complex network theory is also rising day by day, which is a great breakthrough for the traditional research methods of power network, compared with the traditional power communication network, The communication network of the energy Internet is a more complex network, which is more suitable for the study of the complex network theory. Therefore, this paper intends to apply the complex network theory to the reliability analysis of the energy Internet communication network. In this paper, the basic concepts and characteristic parameters of complex network theory are studied, and then the basic characteristics of the future energy Internet and the small-world and scale-free characteristics of the communication network are analyzed. Then, this paper presents a reliability research method based on hierarchical reliability analysis and overall evaluation to analyze the reliability of energy Internet communication network, in which the reliability of topology layer is invulnerable. The method of combining survivability analysis. On this basis, the topology model of the energy Internet communication network is simulated in this paper. The network model is compared with the Internet AS topology and the US electric power network topology from the complex network level, and it is concluded that the network model in this paper has some similar characteristics with the Internet. Compared with the traditional electric power communication network, it meets the requirements of network communication. Finally, this paper analyzes and compares the reliability of the energy Internet communication model with that of a provincial electric power communication network from the aspects of survivability and survivability under the two forms of random attack and deliberate attack. The energy internet communication network model is more reliable than the provincial electric power communication network.
