With the national energy green low-carbon transition, domestic industrial policy guidance and new technology progress, the renewable energy industry has entered a booming stage. At present, several 100 MW renewable energy farms have emerged in the three major energy bases of China's northern, northwestern and southwestern regions. With the increasing number and capacity of renewable energy farms, the engineering and academic communities are also interested in the modelling and simulation of 100 MW renewable farms, as well as the impact of renewable energy farm access on the power grid.

Due to the flexible structure and diversified composition of microgrids, the traditional way of building a small power physical system has been greatly tested in terms of its safety, economy and flexibility of scientific research. The microgrid research platform based on real-time simulation has the flexibility of model construction and real-time simulation, and the authenticity of closed-loop operation with corresponding physical signals, and at the same time, it has the incomparable advantages of the traditional low-power system for the complex working conditions, hazardous experiments, and testing of new system structure.

Power hardware in the loop testing is an extension of signal-level real-time simulation to the power level through the combination of a real-time simulator, a power amplifier and a device to be tested. It can be used to test real power devices, such as energy storage devices, photovoltaic devices, wind turbines and other power devices, and has the characteristics of flexible transformation of system topology and simulation of a variety of grid fault conditions.

The green hydrogen microgrid system consists of photovoltaic distributed power supply, lithium battery storage system, hydrogen fuel cell, electrolysis tank, hydrogen storage tank and loads, creating a light hydrogen storage microgrid energy supply system in the park, and constructing a green, low-carbon and environmentally friendly application scenario for the park in the new era. The electrolysis tank generates hydrogen to be stored in the hydrogen storage tank; the loads include fixed loads, dynamic loads and charging piles.
