【摘要】：電動汽車的能量來源是電力,相比燃油汽車的高污染、高能耗,電動汽車具有噪聲低能效高,無污染物排放等特點,還在節(jié)能、環(huán)保和清潔等方面具有明顯的優(yōu)勢。因此電動汽車的發(fā)展具有廣闊前景和重要的意義,它的大規(guī)模應用被視為緩解能源緊缺和大氣環(huán)境污染最有效方式之一。電動汽車能夠促進低碳經濟實現(xiàn),這種類型的新能源汽車是汽車產業(yè)發(fā)展的必然趨勢。電動汽車的出現(xiàn)會給電力系統(tǒng)帶來挑戰(zhàn)和機遇。電動汽車的充放電行為具有隨機性,如果大量電動汽車進行無序充放電,會顯著增大配電系統(tǒng)的網損。需要對電動汽車的充放電行為進行協(xié)調優(yōu)化,分析其充放電策略,減少電動汽車充放電給電網造成的影響。由于充放電行為完全從屬于用戶的意愿,常規(guī)的調度手段難以進行充放電控制。利用需求響應機制,采取價格杠桿,可以激勵用戶主動對電動汽車的充放電負荷進行有效管理。在一定程度上可以有效的引導電動汽車充放電,減小對電力系統(tǒng)的影響,節(jié)約充電成本,有效提高電網的運行效率。本文先分析電動汽車充放電行為,概述電動汽車充電的模式、電動汽車充電設施,分析比較不同充放電策略。在此基礎上,建立了以電網負荷波動最小和電動汽車用戶是使用成本最小為目標,并設置用戶充放電時間、電池容量、充放電汽車數(shù)量等為約束條件的電動汽車充放電的電價模型。并以某地的負荷數(shù)據(jù)和比亞迪e6為例進行仿真驗證,結果表明采用峰谷分時電價,能夠引導電動汽車用戶合理安排其充放電行為,降低電動汽車使用成本,使得電動汽車對電網造成的影響最小。最后根據(jù)我國電動汽車發(fā)展現(xiàn)狀和現(xiàn)有政策,提出發(fā)展建議。
[Abstract]:The energy source of the electric vehicle is power. Compared with the high pollution, high energy consumption, high energy consumption, low energy efficiency and no pollutant discharge, the electric vehicle has obvious advantages in energy saving, environmental protection and cleaning. Therefore, the development of electric vehicles has broad prospects and important significance, and its large-scale application is considered to be slow. One of the most effective ways to solve the shortage of energy and the pollution of the atmosphere. Electric vehicles can promote the realization of low carbon economy. This kind of new energy vehicle is the inevitable trend of the development of the automobile industry. The emergence of electric vehicles will bring challenges and opportunities to the power system. The charge and discharge behavior of electric vehicles is random, if a large number of electric vehicles are used. The disordered charge and discharge will significantly increase the network loss of the distribution system. It is necessary to coordinate and optimize the charging and discharging behavior of the electric vehicle, analyze its charge and discharge strategy and reduce the influence of electric vehicle charging and discharging to the power grid. Because the charge discharge behavior is completely from the user's will, the conventional method is difficult to carry out charge and discharge control. The use of demand response mechanism and price lever can encourage users to actively manage the charge and discharge load of electric vehicles. To a certain extent, it can effectively guide electric vehicles charging and discharge, reduce the impact on the power system, save charge cost, and effectively improve the operation efficiency of electric network. This paper first analyzes the charge and discharge of electric vehicles. Behavior, an overview of electric vehicle charging mode, electric vehicle charging facilities, analysis and comparison of different charging and discharging strategies, based on this, the establishment of the minimum load fluctuation of power grid and the minimum use cost of electric vehicle users as the target, and set up the charging and discharging time, battery capacity, charge and discharge of the car number and other constraints of electric steam. The electric price model of vehicle charging and discharging is simulated with the load data of a certain area and BYD E6 as an example. The results show that the use of peak and valley time price can guide electric vehicle users to arrange their charge and discharge reasonably, reduce the use cost of electric vehicles and make the electric vehicles have the smallest influence on the electric network. Finally, the electric vehicle is based on the electric steam of our country. The development status and existing policies of vehicles are put forward.
