Abstract: At present, the global energy structure is undergoing a profound transformation. Renewable energy, represented by wind energy and solar energy, is increasingly becoming a key component of power supply with its cleanliness and sustainability. However, the inherent intermittency and volatility of such energy sources, such as wind speed changes and sunshine intensity fluctuations, pose significant challenges to the stable operation of traditional power systems. The specific performance is the violent fluctuation of grid frequency and voltage, which may even lead to system instability and threaten the reliability of power supply. In order to effectively cope with the above challenges, the power system urgently needs to introduce advanced technologies and methods to ensure the reliability and efficiency of its operation. The purpose of this study is to explore the power system simulation and modeling technology, power system frequency regulation method and the application of artificial intelligence in new energy system. The research will analyze the multi-dimensional impact of renewable energy access on power system from the technical and economic aspects, summarize the current development status and challenges of new energy power system, and look forward to the future development trend and main research hotspots.
