Trends and challenges of power distribution IoT services

The power distribution network is the 'last mile' of power grids that connect to users, which mainly consists of 10 kV and 380V lines alongside transformers. The power distribution network is like the nervous system and capillaries of power grids, playing a crucial role in their stable operation. It includes outdoor pole-mounted transformers and indoor distribution rooms in segmented scenarios. As distributed energy storage plants and charging stations are now being connected to power grids, the low-voltage distribution network has become a key area for power grid investment. This presents several challenges and pain points, including:

High Line Loss

• Lack of smart meters
• Inadequate line loss management and electricity theft investigation
• Poor online monitoring and data analysis

Low Power Supply Reliability

• Low power supply reliability, long outage times, and high frequency of faults
• Difficulty in locating faults and long recovery time
• Inefficient O&M and emergency repair instead of inspection

Massive Access to Clean Energy

• Poor network connection and management, low consumption rate
• Lack of security and reliability within power grids
• High demands on power grids
