Asynchronous Grid Interconnection
Abstract:
Asynchronous interconnection and flexible power transmission solutions centered on energy storage systems as the core control node can achieve efficient and flexible interconnection among grids with different characteristics, microgrids, and distributed generation sources. By leveraging the rapid response capabilities of energy storage, these solutions ensure system stability, enable islanded operation during faults, and support black start, thereby breaking through traditional technological constraints and serving as a critical enabler for building a new power system with a high proportion of renewable energy integration.
With energy storage systems acting as the core control node, this solution provides efficient, flexible asynchronous interconnection between grids, microgrids, and distributed generation assets with different voltage levels, frequencies, or operational characteristics. Thanks to millisecond-level fast power response, energy storage delivers real-time active and reactive power support at interconnection points, damping oscillations, stabilizing frequency and voltage, and optimizing power flow to prevent line overloads. This solution overcomes the constraints of traditional synchronous interconnection, enhancing resilience, safety, and operational efficiency for regional grid energy exchange, and is a key enabler for new power systems with high renewable energy penetration.
Core Applications :
- When the main grid experiences a fault, energy storage enables rapid islanded operation to ensure continuous power to critical loads
- Serving as a black-start source to accelerate system recovery
