【摘要】:隨著各類新型的能源發(fā)電技術(shù)的發(fā)展以及考慮到傳統(tǒng)的石化能源的逐漸枯竭和環(huán)境保護的角度,人們越來越關(guān)注和重視使用清潔能源的分布式發(fā)電技術(shù)。這里介紹到的微電網(wǎng)技術(shù),它是一種新型的分布式能源的結(jié)構(gòu)以及組織方式,它的運行方式靈活多變,調(diào)度性能良好,能夠提供安全、高效、可靠地電能。但是為了實現(xiàn)上述發(fā)展目標(biāo),還需要進一步發(fā)展現(xiàn)有電力系統(tǒng)的理論、方法以及模型算法系統(tǒng),這其中的關(guān)鍵就是實現(xiàn)智能化的電力系統(tǒng),通過引進新的計算和通信技術(shù),使得電氣系統(tǒng)和信息系統(tǒng)的進一步整合。信息物理融合系統(tǒng)(Cyber Physical Systems, CPS)可以用來嘗試著解決以上的問題。CPS是集計算、通信和智能控制為多項功能為一體的綜合系統(tǒng),在把物理系統(tǒng)與信息系統(tǒng)進行統(tǒng)一整合之后構(gòu)成了一個全新分析熱點。典型的CPS架構(gòu)分為四層:(1)物理層(2)通信層(3)處理層(4)應(yīng)用層。CPS與微電網(wǎng)的聯(lián)系是未來智能電網(wǎng)發(fā)展的方向。微電網(wǎng)CPS作為智能電網(wǎng)的一個方面。開放和共享的信息是智能電網(wǎng)的基礎(chǔ)。微網(wǎng)是由許多類型的分布式發(fā)電單元、存儲能量裝置,電力負荷以及微電網(wǎng)的發(fā)電調(diào)度中心的能源管理單元組成。微網(wǎng)中,存儲能量系統(tǒng)對如何穩(wěn)定控制微網(wǎng)、如何提高微電網(wǎng)的電能質(zhì)量和連續(xù)不間斷的電源供應(yīng)具有特別重要的作用。本文首先介紹了常見微網(wǎng)和分布式電源的類型以及作用。接著描述了光伏電池,蓄電池以及超級電容器的基本原理,并且構(gòu)建了它們的數(shù)學(xué)物理模型,最后分析了它們在微電網(wǎng)中的作用,這些是對CPS的物理層進行分析研究。然后先引出了統(tǒng)一規(guī)范的IEC 61968國際標(biāo)準(zhǔn),針對CPS中的信息模型,研究了電力系統(tǒng)的公共信息模型(Common Information Model CIM),CIM采用面向?qū)ο蠼5碾娏ο到y(tǒng)的類結(jié)構(gòu),在IEC61968標(biāo)準(zhǔn)的基礎(chǔ)上,研究CIM的建模方法以及控制機組和分布式電源的CIM,接著對光伏電池、蓄電池、超級電容器的CIM模型進行了擴展,這些工作是是對CPS的信息層進行的分析研究。最后,對于微電網(wǎng)的建模仿真問題,針對微電網(wǎng)中的微電源種類多樣且輸出特性各異,傳統(tǒng)的簡易微電源模型所構(gòu)成的微電網(wǎng)平臺很難對現(xiàn)今微電網(wǎng)的研究進行仿真。針對以上情況,搭建了包含的分布式電源為光伏并網(wǎng)逆變器,帶超級電容器的大容量能源儲存系統(tǒng)(Power Conversion System PCS)以及帶蓄電池的大容量能源儲存系統(tǒng)(Power Conversion System PCS)的微電網(wǎng)系統(tǒng),并對其工作過程進行了仿真。為微電網(wǎng)的進一步研究提供了良好的仿真平臺。
[Abstract]:With the development of various new energy generation technologies and the perspective of the gradual depletion of traditional fossil energy and environmental protection, people pay more and more attention to the use of clean energy distributed power generation technology. The microgrid technology introduced here is a new type of distributed energy structure and organization. Its operation mode is flexible and changeable, its scheduling performance is good, and it can provide safe, efficient and reliable electric energy. But in order to realize the above development goal, it is necessary to further develop the theory, method and model algorithm system of the existing power system, the key of which is to realize the intelligent power system, through the introduction of new computing and communication technology. Further integration of electrical and information systems. Cyber Physical Systems (CPSs) can be used to solve the above problems. CPS is a comprehensive system which integrates computing, communication and intelligent control. The integration of physical system and information system constitutes a new analysis hotspot. The typical CPS architecture is divided into four layers: 1) physical layer 2) communication layer 3) processing layer 4). The relationship between CPS and microgrid is the development direction of smart grid in the future. Microgrid CPS is an aspect of smart grid. Open and shared information is the foundation of a smart grid. Microgrid is composed of many types of distributed generation units, energy storage devices, power loads and the energy management unit of the power generation dispatching center of the microgrid. In microgrid, energy storage system plays a very important role in how to control microgrid stably, how to improve the power quality of microgrid and how to supply power continuously. This paper first introduces the types and functions of common microgrids and distributed power sources. Then the basic principles of photovoltaic cells, batteries and supercapacitors are described, and their mathematical and physical models are constructed. Finally, their roles in microgrid are analyzed. These are the physical layers of CPS. Then, the unified standard IEC 61968 international standard is introduced. Aiming at the information model in CPS, the common Information Model model of power system is studied, which adopts the class structure of object-oriented modeling of power system. Based on the IEC61968 standard, the class structure of power system is studied. The modeling method of CIM and the CIMs of control unit and distributed power are studied. Then the CIM models of photovoltaic cells, batteries and supercapacitors are extended. These work is to analyze and study the information layer of CPS. Finally, for the problem of modeling and simulation of microgrid, it is very difficult to simulate the research of microgrid in the traditional micro-power model, aiming at the variety of micro-power sources in micro-grid and the different output characteristics. In view of the above situation, the distributed power supply is composed of photovoltaic grid-connected inverter, large capacity energy storage system with super capacitor and power Conversion System PCS) microgrid system with storage battery. The working process is simulated. It provides a good simulation platform for the further research of microgrid.
