Research on High-Precision Dynamic Adjustment Real-Time Control Technology for New Energy

In recent years, real-time control simulation has become increasingly needed in various scenarios such as on-site debugging and preliminary verification of new energy power electronic converters due to its significant advantages. To solve the problem of significant differences between the control part of the simulation of new energy power electronic converters built using traditional modeling methods and the control system of actual digital chips, a modeling method that can be compared to the control system framework of actual digital chips in MATLAB/Simulink was designed, mainly including S-Function module call, callback function configuration The steps of C file calling, variable interaction between modules, module parallelism, and building an RT-Lab real-time control platform can achieve high-precision real-time control of new energy power electronic converters, and support online dynamic adjustment. Then, using the RT-Lab platform as a real-time controller combined with an actual power electronic converter, the correctness of the S-Function code execution designed according to the modeling method described in this article and the stable and good control effect of the new energy control system during stable operation and low voltage ride through were verified.
