Distribution transformer area flexible interconnection refers to the use of advanced power electronics technologies and intelligent control strategies to enable flexible, efficient, and coordinated operation between traditionally independent distribution transformer areas.
In simple terms, it allows different distribution transformer areas to achieve flexible power resource scheduling and energy sharing, balancing loads and optimizing grid operation.
It is like building an “energy highway”, enabling electricity to flow more smoothly, efficiently, and intelligently between different distribution transformer areas.
Shanghai GCEVO Energy adopts flexible DC technology to achieve interconnection between distribution transformer areas.
Through precise power control capabilities, the system enables:
- Low-voltage network interconnection
- Bidirectional power exchange between distribution transformer areas
- Flexible energy sharing and load balancing
- Improved power supply reliability
- Reduced risk of power outages
Combined with an intelligent energy management and control system, it enables optimized allocation and coordinated dispatch of power resources.
Application Scenarios
1. Load Imbalance Management
For uneven load distribution between different distribution transformer areas or seasonal fluctuations in electricity demand, the system enables bidirectional power support and load balancing, improving overall power utilization efficiency.
2. Electric Vehicle Charging Load Management
With the rapid growth of electric vehicle charging demand, local distribution transformers may face overload risks.
The system enables dynamic capacity expansion through power sharing between distribution transformer areas, effectively reducing transformer overload pressure and improving charging infrastructure accommodation capability.
3. High-Quality Power Supply
During faults or abnormal operating conditions, the system enables:
- Flexible load transfer between distribution transformer areas
- Emergency power support
- Improved power supply reliability
- Enhanced power quality
This ensures continuous and stable power supply for critical loads.
4. Distributed PV Integration
For distribution transformer areas with high penetration of distributed photovoltaic systems, flexible interconnection can:
- Increase renewable energy hosting capacity
- Improve local renewable energy consumption capability
- Enable active voltage regulation
- Reduce voltage fluctuations caused by distributed PV generation
Through intelligent power coordination, the low-voltage distribution network can achieve more flexible, stable, and efficient operation.
Distribution transformer area flexible interconnection transforms traditional passive low-voltage distribution networks into flexible, intelligent, and interactive energy systems. It provides a key technical foundation for future smart grids, distributed energy integration, and the development of new power systems.
