摘要
发输电系统的概率安全性评估,是当前电力系统可靠性研究的学术问题前沿之一。文中提出了基于蒙特卡罗模拟法的发输电系统安全性评估的基本框架,并对安全性指标体系、基本评估算法等进行了详细论述。该框架借鉴了充裕度评估中比较成熟的技术,并将充裕度和安全性统一在同一个评估框架中。最后,对IEEE-RTS79进行了测试计算,验证了评估算法的有效性。
Probabilistic security evaluation (PSE) of composite generation and transmission systems is one of academic frontier of the research on power system reliability. Basic frame of PSE of composite generation and transmission systems including reliability indices, component models and evaluation algorithms is put forward in detail. A Monte-Carlo simulation method based framework is developed, and absorbing comparatively mature technique applied in adequacy assessment. The adequacy and security are integrated in a same assessment frame. At last, the proposed method is applied to the IEEE-RTS79 system.
