“…The first approach is adding additional highswitching-frequency circuits. In [76], two converters with different switching frequency are connected to achieve higher control bandwidth. The converter with higher switching frequency is composed of MOSFETs or SiC devices and the switching frequency can be extended above 50 kHz.…”

High penetration of distributed generations and active loads have enabled the power electronics converter to become a vital component in the modern power grid system, and the broad employment of grid-connected converters at various power levels is making the grid impedance and characteristics complicated. Consequently, in order to validate more advanced features such as the reliability and stability performances of the grid-connected converters, it is becoming an emerging need to emulate the grid behaviors from more aspects. This article serves to foster and investigate the state-of-the-art techniques in the field of ac grid emulation from the perspective of multiple spatial-scales and multiple time-scales. Four major concepts used for grid emulation with featured principles, including concept I (analog simulation with under-scaled components), concept II (grid characteristics in the real-time simulator), concept III (grid characteristics in the converters structure), and concept IV (grid characteristics in the converters controller), are summarized, respectively, in this article. The practical implementation regarding to the circuit topology and the power supply for the grid emulation system are also discussed. Finally, the future trends and conclusions in the field of ac grid emulation are provided.

“…Most converter topologies reported in the technical literature have been designed for AC grid emulation and do not have a sufficient power capability to test modern multimegawatt MV applications [5][6][7][8][9][10]. In the literature, there are two competitive solutions providing an appropriate level of voltage and power for modern MV applications [11,12].…”

Power electronics medium-voltage (MV) systems must comply with the requirements defined in grid codes. These systems’ compatibility with the standards can be validated by specialized testing equipment: grid simulators. This paper presents a hardware in the loop (HiL) implementation and the simulation results of a MV multiphase DC/DC converter designed for MV DC grid emulation. By using ABB’s reliable, patented power converter hardware topology (US 10978948 B2) and by applying advanced control algorithms, the presented system can be used for special purposes, such as the emulation of fault events in a DC-grid used for the certification of other devices, or for other research goals. The presented concept of a power electronics DC-grid simulator (PEGS-DC) is characterized by high power capability and high voltage quality. In this paper, the general idea of a power electronics grid simulator applied for the testing of MV electrical systems is discussed. Then, details related to the PEGS-DC, such as its hardware topology and the applied modulation method are presented. Subsequently, the HiL setup is described. The main scope of this article focuses on model the description and presenting recorded HiL simulations.

“…In a PHIL environment, real‐power devices interact with software models by power amplifiers, which can transform the signal to energy. It provides an efficient means of precisely reproducing the behaviour of energy conversion systems, getting access to their physical features, thus reducing the risk of simulation inaccuracy at the same time [6].…”
