Abstract：Due to the large rotational inertia of synchronous machines，frequency changes caused by faults areminimal. In contrast，new energy systems have smaller rotational inertia，which can result in more significantfrequency variations during faults. These larger frequency fluctuations inevitably lead to changes in ...
