Free QuoteThis seamless transition can be achieved by mitigating the transient variations in the MG voltage, current, phase, and frequency at the point of common coupling. In addition, the proposed strategy is capable, also, to provide a transient-free transition in the DC-link voltage of the utilized PV inverters.
Consequently, seamless and efficient switching between grid-connected and island modes was achieved for the photovoltaic storage hybrid inverter. The enhanced energy utilization efficiency, in turn, offers robust technical support for grid stability. 1. Introduction
The operation of the VSG inverter is implemented in islanding and islanding-to-grid connected modes with and without the pre-synchronization process. Seamless switching between islanding and grid-connected mode. Fast switching from the islanding to grid mode after the pre-synchronization conditions are met.
MGs should be able to operate in grid-connected mode or in islanding mode. At the same time, they should be able to transfer seamlessly from one mode to the other without the interruption of the power supply. In this paper, a proposed control strategy for operating the MG-based PV inverters in different operating modes has been presented.
The maximum frequency deviation is reduced to 1.25%, and the stabilization time is shortened by 0.13 s compared to traditional control methods. Additionally, the inverter's output current increases uniformly, unaffected by the control mode transition, ensuring a smooth switching process. 4.3. Transition From Grid-Connected Mode to Islanded Mode
A Simulink model was constructed to validate the effectiveness of the enhanced control strategy, ensuring efficient and seamless transitions between grid-connected and island modes for the photovoltaic storage hybrid inverter.
