Abstract:
With the continuous expansion of new energy grid integration, the stability issues of grid frequency and voltage have become increasingly prominent. New energy stations need to have the ability to actively support the grid quickly, including virtual inertia, primary frequency modulation, and voltage regulation functions. At the same time, they also need to have adaptive control capabilities to dynamically adjust support strategies and control parameters according to the operating state of the power grid. This paper introduces the functional requirements, overall architecture design, adaptive control strategies, system implementation schemes, and engineering application effects of the active support system for new energy stations. The adaptive control method has significantly improved key performance indicators such as frequency regulation accuracy and voltage regulation accuracy compared with traditional control methods. The adaptive control technology for active grid support by new energy stations provides a reliable and flexible solution for large-scale new energy grid integration, which is of great significance for promoting new energy consumption and ensuring the safe and stable operation of the power grid.
