Thedevelopment of modern control theory makes the control of energy storage device easierand more flexible and the application field of energy storage device bees more widely.In this paper, the ways, functions and feasibility of energy storage devices applied inmicrogrid are studied. Firstly, this paper studies the principle and structures of microgrid and summarizestechnical requirements of each part of a microgrid and expounds the significance ofmicrogrid in solving the existing problems of power system. This paper also analyzes theimportantance of energy storage technology in microgrid, and gaves a detailed descriptionof energy storage device applied in microgrid. The present development of energy storagetechnology is introduced and the advantages and disadvantages of various energy storagetechnologies are pared.Secondly, this paper studies the principles and structures of energy storage technologyand sets up unified models of energy storage system based on paring the monpoints of different energy storage devices. This paper studies the applications and feasibilityfor an energy storage system to be used in microgrids as micro power sources and energystorage devices, and gaves the application patterns of energy storage system used inmicrogrid and achieves a conclusion that there is no problem for an energy storage systemto be used in microgrid. This paper designs the correspongding control system and studiescapacity selection of energy storage system in microgrid and matching between differentenergy storage devices.II華 中 科 技 大 學(xué) 碩 士 學(xué) 位 論 文 Finally, taking SMES as an example, the energy storage system applied particularly inmicrogrid is tested by digital simulation in the environment of MATLAB/Simulink. Thispaper tests the properties of superconducting tapes and studies the properties of SMES andbuilds the SMES models and control systems. This paper studies how SMES can improve the voltage at the load terminal and how SMES can inhibit power oscillations in Microgrid by digital simulation. In this paper, the impacts of SMES parameters on Power Qualityimproving are studied, the effect of SMES application in microgrid is evaluated and we geta conclusion that SMES could be used in microgrid very well.Keywords: Microgrid Energy Storage Technology SMES Power OscillationIII獨 創(chuàng) 性 聲 明本人聲明所呈交的學(xué)位論文是我個人在導(dǎo)師的指導(dǎo)下進行的研究工作及取得的研究成果。其次，本文介紹了儲能技術(shù)的原理和功能，在比較不同儲能設(shè)備共同點的基礎(chǔ)上，建立了儲能系統(tǒng)的統(tǒng)一模型。：馮光申請學(xué)位級別：碩士專業(yè)：脈沖功率與等離子體指導(dǎo)教師：李敬東20090526華 中 科 技 大 學(xué) 碩 士 學(xué) 位 論 文 摘 要隨著材料技術(shù)的不斷進步與電力電子技術(shù)的飛速發(fā)展，儲能設(shè)備的容量、響應(yīng)速度、能量密度以及效率等各個性能指標(biāo)都得到了極大的提升，儲能設(shè)備的性能隨之有了很大的改善。首先，本文研究了微網(wǎng)的原理和結(jié)構(gòu)，總結(jié)了微網(wǎng)對于其各部分的技術(shù)要求，闡述了其對于解決電力系統(tǒng)現(xiàn)存問題的重要意義，分析了儲能技術(shù)在微網(wǎng)中的重要地位，從而建立起儲能技術(shù)在微網(wǎng)中應(yīng)用研究的整體認識，介紹了儲能技術(shù)的發(fā)展現(xiàn)狀，比較了各種儲能技術(shù)的優(yōu)缺點。本文進行了超導(dǎo)帶材性能試驗，研究了 SMES 的性能，建立了微網(wǎng)中 SMES 的模型及控制系統(tǒng)，對 SMES 改善負荷端電壓和抑制微網(wǎng)功率振蕩兩個應(yīng)用途徑進行了仿真分析，研究了 S
