1. A system, comprising:
a controller that is configured to determine terminal current references based on measured terminal voltages for a transmission line type; and
a plurality of programmable emulators, each of the plurality of emulators comprising a pair of power converters coupled together, the controller being configured regulate each of the power converters based on the terminal current references;
wherein the controller is further configured to generate a node control signal and a plurality of switch control signals,
wherein the plurality of programmable emulators is a second plurality of programmable emulators, the system further comprising:
a first plurality of programmable emulators, each of the plurality of programmable emulators being configurable as one of a plurality of node types responsive to the node control signal; and
a plurality of switches that are programmable to couple ones of the first plurality of programmable emulators to each other responsive to the plurality of switch control signals, to couple ones of the second plurality of programmable emulators to each other responsive to the plurality of switch control signals from the controller, and 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 from the controller.
