Digital Physical Hybrid Simulation

Renewable energy is the development trend of future energy. It is of great significance to research the safety, efficiency, greenness, and environmentally friendly utilization of energy in various aspects such as development, utilization, transmission, distribution, and consumption. In order to promote the research on key technologies of energy management, overcome bottlenecks, produce high-level research achievements, and significantly improve the level of discipline development, it is necessary to establish a smart energy laboratory and research platform. Traditional microgrid experimental platforms have shortcomings: firstly, they mainly focus on the generation, transformation, and storage of electrical energy, with limited interaction with diversified energy sources; secondly, traditional platforms often adopt closed system structures, with poor openness and scalability at the control code and hardware structure levels, making it inconvenient for easy modification and adjustment. The proposed digital-physical hybrid renewable energy research platform addresses the shortcomings of traditional platforms, featuring advancedness, integration of virtual and physical elements, good openness, and excellent expandability.

With the development of new energy technologies, an increasing number of grid-connected inverters are being deployed into the power grid. In this regard, Northeast Electric Power University intends to establish a testing platform to investigate the relevant performance of grid-connected inverters for new energy sources. Based on the advantages of real-time simulators, such as small size, rich IO and communication interfaces, and ease of integration with physical devices for hardware-in-the-loop simulation systems, Northeast Electric Power University has chosen the power system real-time simulator provided by ModelingTech to build this platform for research. This platform connects the actual inverters and programmable DC sources through power amplifiers to study the impact of the control strategies of actual grid-connected inverters on the power grid. Experimental results have proven that this testing methodology is an important approach for studying distributed energy sources, equipment testing, and grid interconnection technologies.

The experimental study on the impact of large-scale power grid load fluctuations on microgrids.
The experimental study on the impact of large-scale power grid load fluctuations on microgrids.

During large-scale power grid load fluctuations, which cause bus voltage fluctuations, the voltage of the microgrid also changes in response to the variations in the main power grid. This allows for the analysis and study of microgrid performance during the transition process.
