What are the switching strategies for bidirectional energy storage converters?

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].

What is a bidirectional energy storage converter?

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.

What happens when a bidirectional energy storage converter loses connection?

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
