摘要
分析了传统的电力系统电压崩溃评估方法存在的缺陷,论述了在电力市场环境下实行电压崩溃风险评估的必要性,提出了一种进行电力系统电压崩溃风险评估的方法。该方法综合考虑了电压崩溃的概率和后果,量化了风险指标,通过兼顾风险指标和经济效益为确定系统的最佳运行方式提供了依据。6节点系统和IEEE300节点系统的评估结果证明了该方法的可行性、有效性以及基于该方法编写的电压崩溃风险评估软件的实用性。
The defects of the assessment methods for traditional power system voltage collapse are analyzed. The necessity of conducting risk assessment of voltage collapse in electricity market environment is expounded, and an approach to assess the risk of power system voltage collapse is proposed, in which the probability and consequence of voltage collapse are comprehensively considered and the risk index is quantified,and the foundation to determine optimal operation mode is provided by giving consideration to bo...
