Abstract
With the increasing global energy demand and the growing severity of environmental issues, renewable energy generation has become a critical pathway to achieving sustainable development. This study focuses on the dynamic modeling and simulation analysis of renewable energy generation systems, aiming to establish accurate mathematical models to reveal internal mechanisms and optimize operational performance. To achieve this ob jective, an interdisciplinary approach integrating power electronics, automatic control, and computer simulation techniques is adopted. Dynamic models covering the entire process from energy harvesting to grid integration are constructed for two typical forms of renewable energy generation: wind power and photovoltaic power. An innovative adaptive control algorithm is introduced to address the inherent intermittency and randomness characteristics of renewable energy sources, thereby enhancing system stability and reliability. Extensive simulation experiments conducted on the MATLAB/Simulink platform demonstrate that the proposed model accurately reflects the dynamic characteristics of actual systems and exhibits excellent adaptability under various operating conditions. Furthermore, this model provides a solid foundation for subsequent in-depth research such as fault diagnosis and optimal scheduling, playing a significant role in advancing renewable energy generation technology.
