【摘要】：汽車到電網(wǎng)(Vehicle to Grid,V2G)是由大量電動汽車、充饋電站與電網(wǎng)組成的電動汽車與電網(wǎng)互動信息網(wǎng)絡(luò),電動汽車既可以從電網(wǎng)充電,也可以向電網(wǎng)饋電。如果大量電動汽車不加控制地接入到電網(wǎng),將會給電網(wǎng)帶來“峰上加峰”的壓力,因此電網(wǎng)需要及時獲得電動汽車的充饋電意愿、位置等信息,遠(yuǎn)程監(jiān)控充饋電站的運(yùn)營狀況,根據(jù)電網(wǎng)負(fù)荷狀況對電動汽車進(jìn)行充饋電宏觀調(diào)度。如何在V2G環(huán)境下,以一種有效的方式或機(jī)制保證V2G中電動汽車、充饋電站與電網(wǎng)之間通信的可靠性和時效性,已成為V2G技術(shù)里面臨的一個重要問題。本文針對一種由電動汽車、公共充電站、停車場充饋電站、聚合器、能量供求管理器這些功能組件構(gòu)成的V2G網(wǎng)絡(luò)系統(tǒng),研究分析了該系統(tǒng)充饋電服務(wù)中信息流類型和充饋電過程,以及目前V2G網(wǎng)絡(luò)的通信技術(shù),設(shè)計了能夠?qū)崿F(xiàn)預(yù)約充電、全局饋電、局部饋電和價格管理功能的V2G充饋電調(diào)度管理通信協(xié)議。根據(jù)V2G網(wǎng)絡(luò)中各種功能組件的電力流與信息流通信需求,本文采用兩種V2G網(wǎng)元充饋電調(diào)度管理通信協(xié)議棧模型,在V2G網(wǎng)絡(luò)仿真系統(tǒng)中實現(xiàn)了網(wǎng)元協(xié)議棧模型中的應(yīng)用層管理控制模塊、資源調(diào)度模塊和移動管理模塊,通過仿真測試,檢驗了充饋電調(diào)度管理通信協(xié)議的報文收發(fā)解析處理、充饋電資源調(diào)度、以及電動汽車的移動性管理與充饋電站選擇功能。在此基礎(chǔ)上,對V2G網(wǎng)絡(luò)仿真系統(tǒng)的傳輸成功率和網(wǎng)絡(luò)時延等指標(biāo)進(jìn)行了測試評估。目前還沒有成熟應(yīng)用的V2G充饋電調(diào)度管理通信標(biāo)準(zhǔn),因此本文設(shè)計的V2G網(wǎng)絡(luò)的充饋電調(diào)度管理通信協(xié)議具有一定的理論及應(yīng)用參考價值。
[Abstract]:(Vehicle to grid V2G) is an interactive information network between electric vehicles and power grids, which consists of a large number of electric vehicles, charging stations and power grids. Electric vehicles can be charged from or fed to the power grid. If a large number of electric vehicles are uncontrollably connected to the power network, it will bring the pressure of "peak plus peak" to the power network. Therefore, the power network needs to obtain timely information of the electric vehicle's charging intention, position, and so on, so as to remotely monitor the operation status of the charging station. According to the load condition of electric network, the macro dispatching of electric vehicle is carried out. How to ensure the reliability and timeliness of communication between charging station and power network in V2G by an effective way or mechanism has become an important problem in V2G technology. This paper aims at a V2G network system composed of electric vehicle, public charging station, parking lot charging station, aggregator and energy supply and demand manager. This paper studies and analyzes the information flow type and charging process in the charging and feeding service of the system, and the communication technology of the V2G network at present, and designs a system that can realize the reservation charging and the global feed. Local feed and price management function of V2G charge feeder dispatching management communication protocol. According to the power flow and information flow communication requirements of various functional components in V2G network, two kinds of V2G network element feeder dispatching management communication protocol stack models are adopted in this paper. In the V2G network simulation system, the application layer management control module, resource scheduling module and mobile management module are implemented in the network element protocol stack model. Recharge and feed resource scheduling, mobility management of electric vehicle and selection function of charging and feeding station. On this basis, the transmission success rate and network delay of V2G network simulation system are tested and evaluated. At present, there is no mature communication standard of V2G charging and feeder dispatching management, so the communication protocol designed in this paper has certain theoretical and application reference value.
