“…The voltage source inverter is able to emulate the characteristic of most VSC applications by control of its output currents to follow a pre- defined physical response if the DRE's bandwidth is much greater than the emulating targets. Authors of [21]- [24] provide emulating methodologies for generators, induction motors, wind generators and PV by using small-scale VSCs which are rated at tens of kW. For the proposed MGTB, specific emulating targets are not given for this paper at this time.…”

Microgrid concepts and applications have become more promising during recent years because of the potential for improving system operation, particularly, under emergency conditions. The design and hardware realization of a microgrid laboratory test bed enabling research and development for microgrids, smart-grid systems, and distributed energy integration is presented in this paper. The state-of-the-art regenerative back-to-back voltage source converter topology is used for implementing and emulating the testing capabilities in the MVA range which are defined by IEEE Std 1547.7 TM -2011. An overview of the proposed 13.8-kV microgrid test bed functions and goals are shown. Detailed power electronic circuit hardware, experimental prototype design, and control algorithms are addressed. Hardware test results of case study are shown which display the uniqueness of the proposed test bed which is planned for the research of future microgrids.

A real-time hardware testbed (HTB) has been constructed to emulate the power system by modular regenerative converters. This allows system realistic testing and demonstration with the true measurement, communication, and control. However, the size of the system that can be emulated by the HTB is limited, and certain phenomena are not easy or not needed to be modeled in the HTB. A hybrid emulation platform, which combines real time digital simulator (RTDS) and HTB, is developed in this paper to complement the advantages of RTDS and HTB. A power electronics converter is designed to act as the power interface between the RTDS and the HTB, and an integrated interface with two complementary algorithms is implemented to realize the hybrid emulation stably under different system conditions. At the same time, the closed loop control method under dq0 axis is implemented to realize faster response characteristics, and a time delay correction algorithm is integrated into the Park transformation. Experiment results demonstrate the performance and effectiveness of the hybrid emulation compared with the pure HTB emulation and digital simulation.

“…The determination of the input and output signals depends on the nature of the emulated target. Usually, sources that establish the voltage and frequency of the whole system are emulated as voltage sources [16][17] [20], and the rest are emulated as current sources [11]- [15][18] [22]- [24].…”

A Hardware Test-Bed (HTB) is developed to serve as a platform for power grid emulation. For maximum flexibility, power converters, which can accommodate various control algorithms and behave distinctively based on the applied model and control, is adopted. With the developed emulators, such as generator, load, wind turbine, and PV emulators, diverse research and experiments can be performed by using the HTB. This paper introduces the emulating method, hardware, control and communication structure of the HTB. At the same time, experimental results are compared with simulation to verify the emulation.
