As China accelerates the development of a new-type power system dominated by renewables to meet its "Dual Carbon" goals, the power grid is undergoing a profound structural transformation. The high penetration of renewables and the widespread application of power electronic devices introduce new system characteristics such as low inertia, weak damping, and high uncertainty, posing unprecedented challenges to grid security and stability. This report aims to systematically analyze these challenges and propose corresponding countermeasures. First, it will provide a comprehensive overview of typical security and stability issues in modern power systems, including frequency instability, wide-band oscillations, and the risk of voltage collapse. Second, it will assess the capabilities of existing simulation technologies and analyze their core limitations in terms of model accuracy, computational efficiency, and multi-scale coupling. Finally, looking forward, the report will propose future key directions and strategies for simulation technology, offering a technical roadmap to ensure the reliable operation of future power systems.

This report reviews the critical role of amorphous and nanocrystalline soft magnetic materials in developing high-frequency (HF) transformers, a key technology for compact, high-power-density equipment essential for China's "Dual Carbon" goals. While iron-based nanocrystalline materials are optimal for meeting the demanding requirements of renewable energy applications, challenges in high-frequency losses and manufacturing persist. Significant progress has been made, with Chinese research teams achieving a record 99.85% efficiency in 100 kVA-class prototypes for landmark projects. Current R&D now focuses on scaling this technology to the MVA-class by advancing materials, winding processes, and integrated design to support large-scale renewable energy integration.

Chang Lin of Huairou National Laboratory

This research explores new paradigms for AI-accelerated simulation in power electronics, aiming to break through the limitations of traditional numerical integration methods by leveraging both data-driven and physics-driven approaches. On the data-driven front, we focus on the high-frequency, fast-switching characteristics of power electronic devices. By considering the unique physical properties and parameters of different device types, we discuss data-driven acceleration techniques for high-accuracy Electromagnetic Transient (EMT) models that are specifically adapted to capture these dynamic switching behaviors. Furthermore, we introduce a physics-driven approach by establishing a neural network solver architecture governed entirely by physical laws. This method, often known as a Physics-Informed Neural Network (PINN), is designed to overcome the limitations of traditional numerical methods in terms of computational efficiency and the handling of ill-conditioned equations. This work is significant for establishing a new simulation technology roadmap and platform based on novel principles. It holds the potential to break through traditional computational bottlenecks, thereby meeting the practical needs of both engineering applications and scientific research.

This research addresses the dual challenges facing large-scale offshore wind power systems that utilize multi-terminal VSC-HVDC transmission. These challenges include complex electromagnetic transients during internal faults and the significant threat of multiple-stroke lightning, a prevalent issue in China's coastal regions. The project aims to develop a comprehensive protection framework by first statistically characterizing multiple-stroke lightning parameters. Subsequently, it will investigate key protection technologies for the entire system, covering the unique difficulties of offshore wind turbines, the power transmission network against multiple strikes, and the VSC-HVDC system's vulnerability to electromagnetic transients. The ultimate objective is to develop high-reliability protective equipment and establish a coordinated defense strategy against both overcurrent and overvoltage events.

In power electronic systems, such as those for renewable energy grid integration, the stability analysis of converters is a crucial step. The traditional method, which relies on engineers manually deriving small-signal models, is complex, time-consuming, and difficult to apply to large-scale systems. This report proposes an innovative MATLAB-based solution: by developing plug-and-play modules and utilizing the linearize function, it enables automated, rapid, and accurate small-signal modeling of large-scale converter systems. As verified, this method is stable, reliable, and its accuracy meets the requirements for power grid analysis. It can significantly lower the barrier for engineers to perform stability analysis and algorithm iteration, thereby greatly improving R&D efficiency.
