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.
Simplified structure of PV grid-connected system In the formula, and , respectively, indicate the active and reactive power loss of the line. Usually, the line loss is much less than that of PCC power. and are negligible in formula (1). Besides, the longitudinal component of voltage is far less than its transverse component.
The low PCC voltage has a larger impact for Strategy I because its power control loop is a current control loop, and the current references depend on the PCC voltage. Strategy II has a larger P-Q capability with low PCC voltages and can maintain stability during fault ride-through.
In addition, the inverter control techniques may also impact the converter lifetime and reliability. It is known that the inverter loading depends on the power generation by the PV arrays. Therefore, variation in the mission profile can cause thermal fluctuations in the GCPIs.
