A Grid-forming Photovoltaic Control Strategy Based on the DC Voltage Synchronization
The grid-forming photovoltaic exhibits voltage source characteristics and can operate stably in the weak grid.A grid-forming photovoltaic control strategy is proposed based on the DC voltage synchronization and analyzes the operation principle of the grid-connected photovoltaic converter utilizing DC voltage to operate in the grid-forming control strategy mode.The grid-forming control strategy based on the DC voltage synchronization allows the photovolta-ic to operate at the maximum power point.Finally,the effectiveness of the proposed control strategy is verified by con-troller hardware-in-the-loop experiments.
