Scalable reconfigurable apparatus and methods for electric power system emulation

A system comprising multiple ones of the electric power system apparatuses installed and interconnected in a rack, wherein each electric power system emulator apparatus comprises:

• a chassis;
• a plurality of emulator modules in the chassis, each of the emulator modules comprising:
• first and second transmission path emulator circuits, each having first ports configured to be connected to one another and second ports configured to be connected to another of the emulator modules;
• a first bypass circuit integrated into and configured to bypass the first transmission path emulator circuit;
• a second bypass circuit integrated into and configured to bypass the second transmission path emulator circuit;
• a power node emulator circuit configured to emulate at least one of a source or a load, the power node emulator circuit configured to be connected to the first ports of the first and second transmission path emulator circuits;
• and
• a control circuit in communication with and configured to control each of the first transmission path emulator circuit, the second transmission path emulator circuit, the first bypass circuit, the second bypass circuit, and the power node emulator circuit.
