Renewable energy resources are becoming the dominating element in power systems. Along with de-carbonization, they transform power systems into a more distributed, autonomous, bottom-up style one. We speak of Smart Grid and Microgrid when distributed energy resources take over. While being a means to improve technical and financial efficiency, planning, operations, and carbon footprint, it is these new technologies that also introduce new challenges. Reliability is one of them, deserving a new way of describing and assessing system and component reliability. This paper introduces a new reliability framework that covers these new elements in modern power systems. It can be seen that reliability assessment of modern power systems also requires introducing local reliability concepts as well as incorporating different electro-magnetic/mechanical stability issues.

现代电力电子电力系统的可靠性概述

可再生能源正在成为电力系统中的主要元素。随着脱碳，他们将电力系统转变为一种更加分散，自治，自下而上的样式。当分布式能源接管时，我们谈到了智能电网和微电网。这些技术不仅可以提高技术和财务效率，规划，运营和碳足迹，还带来了新的挑战。可靠性是其中之一，值得采用一种描述和评估系统及组件可靠性的新方法。本文介绍了一个新的可靠性框架，该框架涵盖了现代电力系统中的这些新元素。
