The objective of BP4-4.11 task is to develop an Asynchronous Microgrid Power Conditioning System which can be modular MVAC (13.8 kV AC) to MVAC (4,160 V AC and 13.8 kV AC) power conditioning system blocks (PCSB) that can be used for grid interconnection of Megawattscale power flow control microgrids (asynchronous MVAC microgrids). The PCSBs shall have bidirectional
power flow capability and be scalable so that they can be used for a broad range of power flow control microgrids of different scale (100 kW to multi-MW) including microgrids that have net generation or net load power flow at the point of connection to the larger grid. This bi- directional
power flow solution should be 60 Hz transformer-less. This modular app roach is intended to result in higher-volume, lower-cost power electronics building blocks that service many applications at standard voltages: 4,160 V AC and 13.8 kV AC. This Microgrid PCS solution should enable multi-port
integration of renewable energy sources to the main grid. The overall efficiency of the Microgrid PCS should be > 98% and with low/partial load ( 95%.
