摘 要:隨著電動汽車規(guī)模化接入電網(wǎng),用戶無序的充電行為會對電力系統(tǒng)的安全性和經(jīng)濟性產(chǎn)生負面影響。提取不同類型電動汽車充電負荷特性,并分析了集群電動汽車與電網(wǎng)在系統(tǒng)穩(wěn)定性方向的交互與影響;仿真結(jié)果表明,通過電動汽車充電時間及充電功率等靈活資源的集群調(diào)控,能有效利用電動汽車負荷的可調(diào)度特性,發(fā)揮更多的需求側(cè)潛能,實現(xiàn)需求側(cè)負荷削峰填谷的目標。
關(guān)鍵詞: 電動汽車;需求響應(yīng);電力系統(tǒng);負荷特性

Abstract: With the large-scale integration of electric vehicles into the power grid, the disorderly charging behavior of users will have a negative impact on the safety and economy of the power system. This paper extractes the charging load characteristics of different types of electric vehicles, and the interaction and influence of cluster electric vehicles and power grid in the direction of system stability are analyzed.The simulation results show that through the cluster regulation of flexible resources such as charging time and charging power of electric vehicles, the schedulable characteristics of electric vehicle load can be effectively utilized, more demand-side potential can be brought into play, and the goal of peak cut on the demand side load can be achieved.
Key words: electric vehicle; requirement response; power system; load characteristic
