Abstract

Unpredictable variations in load demand and unanticipated component failures are progressively impacting the operation of modern power systems, making system evaluation more stochastic in nature. Although deterministic approaches were formerly the norm for determining system status, probabilistic approaches have greatly improved the capacity to capture the stochastic behavior characteristic of power system operations. The presented work in the paper recommends the use of probabilistic modelling approaches with deterministic approaches, highlighting their crucial function in augmenting the reliability and security of contemporary power systems to unanticipated failures. In this paper, N − 1 security criteria based reliability of the composite power system (CPS) is proposed using an integrated deterministic and probabilistic framework (D-P) considering outage of the transmission line. For the deterministic approach (DA), line overloading on available lines is determined using the static security index (SSI). For the probabilistic approach (PA), reliability indices such as expected loss of power (ELOP), expected frequency of contingency (EFOC), expected loss of load (ELOL), probability of load curtailment (PLC), and expected duration of load curtailments (EDLC) are calculated. Further, for each contingency, a performance index is determined using both approaches to assess the severity of the contingency that occurred on the power system. Based on the N − 1 security criteria based reliability analysis using an integrated D-P framework, a credible critical set of transmission lines is obtained, which can serve as important information to system operators. The proposed techniques have been tested on IEEE 24 bus reliability test system (RTS).
N - 1 基于安全标准的确定性和概率性综合电力系统可靠性框架
不可预测的负荷需求变化和不可预知的组件故障正逐步影响着现代电力系统的运行,使系统评估更具随机性。虽然确定性方法以前是确定系统状态的常规方法,但概率方法已大大提高了捕捉电力系统运行的随机行为特征的能力。本文介绍的工作建议在使用确定性方法的同时使用概率建模方法,强调概率建模方法在增强当代电力系统的可靠性和安全性以应对意外故障方面的重要作用。本文提出了基于 N - 1 安全标准的复合电力系统 (CPS) 可靠性,使用了一个综合确定性和概率框架 (D-P),考虑了输电线路的断电问题。对于确定性方法 (DA),使用静态安全指数 (SSI) 确定可用线路上的线路过载情况。对于概率方法 (PA),则要计算可靠性指数,如预期功率损失 (ELOP)、预期事故频率 (EFOC)、预期负荷损失 (ELOL)、负荷削减概率 (PLC) 和预期负荷削减持续时间 (EDLC)。此外,对于每种突发事件,都会使用这两种方法确定一个性能指标,以评估电力系统中发生的突发事件的严重程度。在基于 N - 1 安全标准的可靠性分析基础上,利用综合 D-P 框架,可获得一组可信的输电线路临界值,这对系统运营商来说是非常重要的信息。所提出的技术已在 IEEE 24 总线可靠性测试系统 (RTS) 上进行了测试。
