Grid-Connected Renewable Energy Generation Systems with Machine Interface and Its Control Technology

---

Introduction:

As global energy transition accelerates, the integration of high-penetration renewable energy has become an inevitable trend in the development of new power systems. Renewable energy equipment connected to the grid via power electronic converters features low inertia and weak grid support capability, resulting in a continuous decline in system equivalent inertia and the emergence of stability issues such as wide-band oscillations, posing severe challenges to the traditional grid security and stable operation mechanisms centered on synchronous generators. Grid-Forming (GFM) converter control technology, with its ability to autonomously establish terminal voltage and frequency, has become a research hotspot in the current field. Motor-interface Renewable Energy Grid-Connected Power Generation Systems emerge as an innovative grid-connected topology. Through the synergistic optimization of topology architecture and control strategies, they can achieve efficient power transmission, reactive power regulation, and grid-forming support under steady-state operating conditions, while also providing superior transient support capability compared to traditional power electronic converter interfaces during grid faults. This special issue focuses on the topology design, operation and control strategies of motor-interface renewable energy grid-connected power generation systems, and their applications in new power systems, aiming to promote theoretical innovation and engineering practice in this field, thereby providing technical support for the secure and stable operation of high-penetration renewable energy power systems.
The topics of interest include, but are not limited to:
1. Topology design and modeling of motor-interface renewable energy grid-connected generation systems;
2. Steady-state power transmission control strategies for motor-interface renewable energy grid-connected generation;
3. Grid-forming characteristics and active support technologies of motor-interface renewable energy grid-connected generation;
4. Transient support control under grid faults for motor-interface renewable energy grid-connected generation;
5. Comparison and coordination between motor-interface and power electronic converter grid-integration technologies;
6. Applications and demonstrations of motor-interface renewable energy grid-connected generation in new power systems;
