Power electronics converter based reconfigurable grid emulation platform

A method, comprising:

• generating, using a controller, a node control signal and a plurality of switch control signals;
• configuring each of a first plurality of programmable emulators as one of a plurality of node types responsive to a node control signal from a controller responsive to the node control signal;
• configuring each of a second plurality of programmable emulators as a long-distance transmission line emulator, a Direct Current (DC) line emulator, a high voltage DC converter emulator, or a short-distance transmission line emulator;
• programming a plurality of switches to couple ones of the programmable emulators to each other responsive to the plurality of switch control signals;
• programming the plurality of switches to couple ones of the second plurality of programmable emulators to each other responsive to the plurality of switch control signals;
• and
• programming the plurality of switches to couple the ones of the first plurality of programmable emulators to the ones of the second plurality of programmable emulators to each other responsive to the plurality of switch control signals.
