The effectiveness of the proposed method is verified. The data-driven modeling has its interpretability. The utilization of data-driven modeling techniques has been extensively employed in the simulation analysis, power prediction, and condition monitoring of photovoltaic power generation systems.
The grid-connected photovoltaic power generation system can be classified as a multi-time scale system due to the varying dynamics of its components. Specifically, the power electronic components in grid-connected inverters operate at a high switching frequency of approximately 20 kHz, indicating a fast time scale behavior.
Digital twin design In order to validate the proposed method of digital twin modeling, a simulator for LCL single-phase grid-connected inverter was established in a PC, with its specifications detailed in Table 1.
Conclusion A novel digital twin approach, integrating physical mechanisms and operational data, is suggested for estimating unknown parameters in complex power systems using non-destructive techniques.
