摘要
在PV曲线基于临界功率的数学表述基础上，从供应方、需求方矛盾相互关联的角度，对电力系统弱节点紧急运行模式进行了解析。供需矛盾尖锐的程度，明显影响需求侧用户动态用电行为，考虑用户群体的动态用电行为，对分析和解释电力系统电压失稳和电压崩溃很有必要。
In this paper, the urgent voltage operating patterns of the powr systems are studied. Based on the mathematical descriphon of PV curves in terms of the crihcal powr, it is analyzed the viewpoint of contradictory then the supply and demandsides. Sharpness of the supply - demand contradictory obviously influence the user dynamic behavior of the demand side. Duringdiscussion with regard to voltage instablity and voltage collape, it is an unnegligible side to consider dynamic behavior of the usercrowd.
