【摘要】：針對電動汽車的充電特性,本文以實(shí)測充電數(shù)據(jù)為基礎(chǔ),擬合其五階高斯充電分布規(guī)律,在此基礎(chǔ)上研究了多場景下含電動汽車的配網(wǎng)電壓穩(wěn)定裕度,分析采用無序充電和峰谷分時(shí)電價(jià)調(diào)控充電方式時(shí),不同滲透率的電動汽車充電對配電網(wǎng)電壓穩(wěn)定裕度造成不同程度的影響,以及電動汽車以不同比例接入充電站節(jié)點(diǎn)時(shí)對配網(wǎng)電壓穩(wěn)定裕度的影響,并依據(jù)系統(tǒng)電壓穩(wěn)定裕度采用一種可切負(fù)荷控制策略,以提高系統(tǒng)應(yīng)對電壓失穩(wěn)能力。
[Abstract]:In view of the charging characteristics of electric vehicles, based on the measured charging data, this paper fits the five order Gauss charge distribution law. On this basis, the voltage stability margin of the electric vehicle with multiple scenes is studied. The charge matching of electric vehicles with different permeability with different permeability is analyzed when disordered charging and peak valley time price regulation and charge mode are used. The voltage stability margin of the power grid has a different degree of influence, as well as the influence on the voltage stability margin of the distribution network when the electric vehicle is connected to the charging station in different proportions, and a tangent load control strategy is adopted to improve the system's ability to cope with the voltage instability according to the system voltage stability margin.
