Virtual Synchronous Generator Control Technology Simulation Source Code

This simulation source code implements virtual synchronous generator (VSG) control technology, designed to control inverters by mimicking synchronous generator characteristics. The core algorithm typically includes mathematical models simulating rotor inertia (swing equation implementation) and voltage/frequency regulation (droop control functions). This technology employs software-based synchronization techniques to emulate synchronous generator behavior, thereby enhancing inverter efficiency and stability through features like virtual impedance calculation and power-angle characteristic simulation. By adopting VSG control, inverters can better adapt to diverse power demands, improving overall power system performance and reliability with functionalities such as grid-supporting mode switching and active power-frequency coordination. Additionally, the technology reduces inverter energy consumption through optimized PWM modulation strategies and dynamic voltage compensation, ultimately lowering operational costs. Key code modules may involve phase-locked loop (PLL) synchronization, governor emulation blocks, and excitation system simulation. In summary, VSG control technology serves as an effective solution for power systems, significantly enhancing system performance and reliability through programmable virtual inertia adjustment and grid-following/grid-forming operational modes.
