Abstract

This paper proposes an improved model for the reliability assessment of power systems considering component failures of variable energy resources (VER). The inherent intermittency of VER such as solar photovoltaic (PV) and wind farms, along with their susceptibility to component failures, present significant challenges to reliable system operation. These issues, combined with power grid operation and network constraints, complicate the reliable operation of VER-integrated power systems. To address these concerns, this paper introduces a reliability assessment framework that considers VER input variability, its impact on component availability, and their resulting impact on overall system reliability. Stochastic models based on discrete Markov processes are developed to incorporate variable irradiance, wind speeds, and their effects on PV and wind component failure rates. A next-event and state transition-based approach is then developed to integrate the stochastic models into a mixed-timing sequential Monte Carlo simulation framework for composite reliability assessment. Case studies on the RTS-GMLC system demonstrate the effectiveness of the proposed model in evaluating the reliability of VER-integrated systems.

考虑变能源组件故障的电网可靠性分析

本文提出了一种考虑变能源组件故障的电力系统可靠性评估改进模型。太阳能光伏（PV）和风力发电场等VER固有的间歇性，以及它们对组件故障的敏感性，对系统的可靠运行提出了重大挑战。这些问题，再加上电网运行和网络约束，使ver集成电力系统的可靠运行复杂化。为了解决这些问题，本文引入了一个可靠性评估框架，该框架考虑了VER输入的可变性，它对组件可用性的影响，以及它们对整个系统可靠性的最终影响。建立了基于离散马尔可夫过程的随机模型，以纳入可变辐照度、风速及其对光伏和风力组件故障率的影响。然后，开发了一种基于下一事件和状态转换的方法，将随机模型集成到混合时序时序蒙特卡罗仿真框架中，用于复合可靠性评估。以RTS-GMLC系统为例，验证了该模型对ver集成系统可靠性评估的有效性。
