To enhance the security of IMGs, this paper proposes a power instruction correction (PIC) based frequency response strategy for GFM inverter in IMGs. Firstly, the fundamental principle of the PIC strategy that originates the basic droop control is theoretically analyzed.
As presented in Sec 2, the frequency response of the IMG relies on the interaction of the load power and the power instruction of the GFM inverter. Since the disturbances are directional, namely, positive disturbances and negative disturbances, they may be offset by each other, and Eq.
These safeguards are essential to protect both the inverter and the broader power network from excessive current transients that may arise due to load fluctuations, grid disturbances, or fault events. Maintaining a fixed and regulated DC voltage is paramount for ensuring optimal inverter performance.
Based on the power quality requirement that the grid voltage frequency variation should not be greater than 1 % and the voltage amplitude variation should not be greater than 5 %, the minimum permissible angular frequency of the inverter output is 310.86 rad/s and the minimum voltage amplitude is 295.45 V.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
