【摘要】：在全球經(jīng)濟(jì)強(qiáng)勁增長,石油生產(chǎn)國剩余產(chǎn)能不足以及國際局勢動蕩等多方面的影響下,化石能源短缺問題日益嚴(yán)重。電動汽車具有能源清潔,低耗能等優(yōu)點(diǎn)。世界各國都在不斷的進(jìn)行相關(guān)方面的研究,我國也在不斷推進(jìn)電動汽車的發(fā)展。當(dāng)前電動汽車產(chǎn)業(yè)正步入快速發(fā)展期,未來的電網(wǎng)將會承受大規(guī)模的電動汽車充電負(fù)荷；本文的研究目的是探索電動汽車充電對電網(wǎng)的影響以及對策措施研究。 論文首先對國內(nèi)外電動汽車入網(wǎng)充放電的研究現(xiàn)狀進(jìn)行了總結(jié)學(xué)習(xí)。在此基礎(chǔ)之上分析了電動汽車充電負(fù)荷的主要影響因素與建模方法；討論了當(dāng)前電動汽車入網(wǎng)建模的研究現(xiàn)狀,并從電網(wǎng)負(fù)荷能力,電能質(zhì)量,經(jīng)濟(jì)性和二氧化碳排放量等方面詳細(xì)分析了電動汽車充電對電網(wǎng)的影響；從為電力系統(tǒng)提供輔助服務(wù),與新能源的協(xié)調(diào)匹配,電網(wǎng)系統(tǒng)的經(jīng)濟(jì)性,電池壽命以及安全性等四方面總結(jié)了電動汽車?yán)胿2G技術(shù)入網(wǎng)放電的影響。 本文分析了影響充電負(fù)荷的四個因素,根據(jù)北京市的實(shí)際情況,建立合理的數(shù)學(xué)模型,運(yùn)用蒙特卡洛的仿真方法對北京市在未來不同時期的電動汽車充電負(fù)荷進(jìn)行了仿真計算。 根據(jù)上述計算的電動汽車充電負(fù)荷曲線,研究其對電網(wǎng)系統(tǒng)的影響。通過對典型電網(wǎng)算例進(jìn)行分析,發(fā)現(xiàn)大規(guī)模的無序充電行為會對電網(wǎng)的負(fù)荷,電壓以及線損均造成不利影響。論文同時對未來電動汽車充電站的選址進(jìn)行了研究,實(shí)驗(yàn)結(jié)果表明,單就電網(wǎng)方面而言充電站接入點(diǎn)離電源點(diǎn)越近,充電負(fù)荷對電網(wǎng)系統(tǒng)的各方面影響就越小。 最后,論文提出了分時計價的政策措施引導(dǎo)電動汽車用戶的充電行為,降低無序充電行為給電網(wǎng)系統(tǒng)帶來的不利影響。
[Abstract]:Under the influence of strong global economic growth, insufficient surplus production capacity in oil-producing countries and the turmoil in the international situation, the problem of fossil energy shortage is becoming increasingly serious. Electric vehicles have the advantages of clean energy and low energy consumption. Countries all over the world are constantly carrying on the related research, and our country is pushing forward the development of electric vehicles. At present, the electric vehicle industry is entering a period of rapid development, the future power grid will bear a large scale of electric vehicle charging load; The purpose of this paper is to explore the influence of electric vehicle charging on power grid and the research of countermeasures. Firstly, this paper summarizes and studies the current situation of charging and discharging of electric vehicles at home and abroad. On this basis, the main influencing factors and modeling methods of electric vehicle charging load are analyzed, and the current research status of electric vehicle network modeling is discussed, and the load capacity and power quality of electric vehicle are discussed. In the aspects of economy and carbon dioxide emission, the influence of electric vehicle charging on power grid is analyzed in detail, from providing auxiliary services for power system, matching with new energy, and economy of power grid system, Four aspects of battery life and safety are summarized in this paper, such as battery life and safety. This paper analyzes the four factors that affect the charging load of electric vehicles by using v2G technology, and establishes a reasonable mathematical model according to the actual situation in Beijing. Monte Carlo simulation method is used to simulate the charging load of electric vehicles in Beijing in different periods in the future. According to the calculated charging load curve of electric vehicles, the influence on power grid system is studied. Through the analysis of typical power network examples, it is found that large-scale disordered charging behavior will adversely affect the load, voltage and line loss of the power network. At the same time, the thesis studies the location of the charging station of electric vehicle in the future. The experimental results show that the closer the charging point is to the power supply point, the smaller the impact of charging load on all aspects of the power system is. In this paper, time-sharing pricing policies and measures are proposed to guide the charging behavior of electric vehicle users and to reduce the adverse effects of disordered charging behavior on the power grid system.
