A new type of scaled-down network simulator composed of power electronics

This paper describes a new type of scaled-down simulator for distribution grid. The most significant component in this proposal is an active interface for connecting actual size power conditioners with a scaled-down network simulator. The fundamental function of the interface is to transfer electrical properties: voltage and current at a terminal of the network side are transferred to another terminal of the power conditioner side by multiplying factors of n and m respectively. At the same time, the conditional side current and voltage have to be transferred to the network side by multiplying 1/n and 1/m, and vice versa. This principle has been demonstrated by an OP Amp circuit in this time. Other practical issues to realize this entirely new idea are also discussed.
