Application of Flexible Regulation Technology for Distributed Energy Storage Based on Power Harmony Carrier Communication

With the increasing depth of low-voltage distribution networks' participation in power demand response, distributed energy storage systems are required to engage more extensively in regulation to adapt to the operational needs of power grids across diverse scenarios. This paper focuses on the construction of intelligent systems and the generation of regulation strategies for distributed energy storage systems, proposing a distributed energy storage management and control system based on edge-terminal hardware equipment integrated with power Harmony carrier communication, which has been applied in practical projects. The terminal layer achieves comprehensive state perception of energy storage equipment through monitoring devices; the edge layer realizes local data aggregation, command forwarding, and hardware encryption via the power Harmony carrier communication module embedded in the integrated terminal; the cloud layer consists of an IoT device management platform and a distributed energy storage control platform, enabling functions such as the generation of energy storage regulation commands and the visualization of operational status. The system forms a complete closed-loop workflow covering device access, state monitoring, and intelligent regulation. Application results after testing and commissioning demonstrate that the system can enhance the operational safety and energy utilization efficiency of energy storage equipment while reducing operation and maintenance costs.
