The bidirectional energy storage converter in the power grid must possess the capability for seamless switching between grid-connected and islanding modes to cope with frequency and voltage dips resulting from unforeseen circumstances in the main grid.
A novel topology of the bidirectional energy storage photovoltaic grid-connected inverter was proposed to reduce the negative impact of the photovoltaic grid-connected system on the grid caused by environmental instability.
Currently, there are two primary switching strategies for bidirectional energy storage converters: one is the switching strategy combining PQ control and V/f control, and the other is the switching strategy based on droop control [3, 4, 5, 6].
The use of bidirectional energy storage inverters is crucial for enhancing power exchange in hybrid Alternating Current/Direct Current (AC/DC) networked microgrids [1, 2]. But the switching between grid-connected and off-grid modes of bidirectional energy storage inverters can cause shock effects, impacting the safety of load power consumption.
Conversely, during the transition from islanded to grid-connected mode, this paper proposes a composite pre-synchronization control strategy based on droop control, which enables precise tracking of the phase, amplitude, and frequency of the output voltage of the bidirectional energy storage inverter relative to the grid voltage.
When the bidirectional energy storage converter loses connection with the main grid, due to the loss of the grid’s clamping effect and without switching to islanding mode, the PCC frequency will undergo a disturbance process until it reaches a new steady state. During this process, the load phase angle is
