摘要

To achieve the dual carbon goal, China has decided to develop energetically clean energy and will develop a new energy system that uses low inertia to reduce carbon emissions. This new technology will have a significant impact on the security and stability of the system. In order to accurately identify system risks, this chapter presents an evaluation study on the influence of inertial errors on the risk of new power supply systems. An evaluation index system is constructed in three dimensions: the generation, load side, and energy storage side. To measure the evaluation results, the AHP method and the cloud model are selected. This suggests that inertial errors have a significant impact on the risk of new electrical systems.
