Bidirectional Energy Storage Inverter and Off-Grid Switching Control Strategy 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.
