由于电力系统中可再生能源（RE）的高渗透水平而导致的电力系统惯性能量的侵蚀是当前世界各地大多数系统运营商的一个初期问题。主要问题是同步发电机与基于逆变器的发电机的位移，因为后者不向电力系统提供任何惯性能量。电力系统因此变得容易受到大系统事件（例如大发电机或负载的突然损失）的影响，并且在基于逆变器的系统中，这可能导致灾难，例如由于频率的快速变化率而导致整个电力系统的完全崩溃。本文着重于电力系统的惯性作为RE渗透水平的增加，也探讨了可能的缓解措施，如需求响应技术。
Erosion of power system inertial energy due to high penetration levels of renewable energy (RE) sources in a power system is a current teething issue with most system operators everywhere. The main issue is displacement of synchronous generators with inverter-based based generators, as the latter do not provide any inertial energy to the power system. The power system thereby becomes vulnerable to large system events (like sudden loss of a big generator or load) and in an inverter-based system this could result in catastrophes such as total collapse of the whole power system due to rapid rate of change of frequency. This paper focuses on power system inertia as RE penetration levels increase and also explores possible mitigation measures such as demand response techniques.
