Key Advantages of VSG Mode

Supports islanded operation

In islanded mode, VSG can proactively establish and maintain voltage and frequency references, providing stable power to local loads and ensuring power continuity for critical facilities.

Improves power quality

VSG has reactive power-voltage droop control capabilities, providing reactive power support when grid voltage drops, shortening voltage recovery time, and helping to maintain bus voltage within ±1%. Within the network:

▶ Enhancing adaptability to weak grids: In long-distance transmission or remote weak grid areas, VSG reduces reliance on phase-locked loops (PLLs) through virtual synchronization characteristics, enhancing system robustness to impedance changes and reducing the risk of grid disconnection.

▶ Supporting participation in the power ancillary services market: VSG devices can flexibly provide ancillary services such as frequency regulation, voltage regulation, and black start, improving the economic benefits and market competitiveness of energy storage or new energy projects.

▶ Compatible with multi-source collaboration and multi-machine parallel operation: Multiple VSG devices can achieve parallel operation similar to traditional power plant units through coordinated control (such as sharing virtual frequency and reactive power sharing strategies), supporting efficient collaboration of various distributed power sources such as photovoltaic, wind power, and energy storage in microgrids

▶ Possessing primary frequency regulation capability: VSG automatically adjusts active power output according to system frequency deviation, achieving primary frequency regulation function similar to traditional units. It can quickly respond to frequency fluctuations without external communication, improving system frequency stability.
