摘要

跨区电网互联、大规模新能源并网、需求侧互动将给大电网的运行带来更多的复杂性、不确定性与风险性。文中在研究电网风险评估模型的基础上，提出一种提高断面输电能力的紧急控制措施风险量化评估方法。该方法考虑切机、切负荷、直流调制等紧急控制措施的代价以及《电力安全事故应急处置和调查处理条例》出台对安全稳定控制切负荷的影响，以暂态失稳风险指标的形式量化评估系统暂态稳定水平，同时分析了不同控制量对于风险值的影响。通过将系统安全稳定性与经济性相结合，以指标形式表征提升单位断面输电能力的代价，达到对紧急控制措施进行综合评价与筛选的目的。

Abstract

Transregional interconnection of power systems

large-scale integration of renewable energy and interaction on the demand side are bringing new challenges to the operation of large-scale power system

such as complexity

uncertainty and riskiness. A risk quantitative assessment method of emergency control measures is proposed to improve power grid transmission capacity based on a study of the risk assessment model. Both the cost of emergency control measures of generator tripping

load shedding and HVDC modulation and stabilized control strategies influenced by Rule 599

are taken into consideration in this method. The transient stability level of power systems will be quantitatively assessed in the form of transient instability risk index. Also the influence of different control quantities on risk values is analyzed. By combining power grid security and stability with economy

this paper characterizes the cost of improving unit transmission capacity by utilizing the index to achieve the goal of comprehensively evaluating and screening emergency control measures.
