电网模拟器需要控制关键电网特性，这些特性可能会暴露与分布式发电（DG）集成到交流电网相关的系统兼容性问题。本文介绍了一个电网模拟器，提供了可控性的阻抗，电压，谐波和频率在几个DG单元的交流互连的发展。在使用背靠背VSC拓扑的电网模拟器的实施中，解决电磁兼容性（EMC）问题对于产生可靠和安全的电网模拟器操作是必不可少的。各种实验测量，以验证电网模拟器控制系统及其电磁干扰（EMI）滤波器的设计。
A grid simulator is required to have control over the key grid characteristics that may expose system compatibility problems related to the integration of distributed generation (DG) to the ac grid. This paper presents the development of a grid simulator that provides controllability of the impedance, voltage, harmonics and frequency at the ac interconnection of several DG units. In the implementation of the grid simulator using a back-to-back VSC topology, resolving problems of electromagnetic compatibility (EMC) are essential to yield a reliable and safe grid simulator operation. Various experimental measurements are presented to verify the grid simulator control system and its electromagnetic interference (EMI) filter design.
