In the development of modern power systems, energy storage power stations play a critical role in peak shaving and frequency regulation. As such, standardization and openness in device communication are essential. However, in practice, many existing energy storage stations or solar-plus-storage projects face a serious "protocol wall" problem.
On-site, existing Energy Management Systems (EMS), PV inverters, and certain protection devices typically communicate using the IEC104 protocol, which is a standard in the power industry. Meanwhile, upper-level platforms—such as smart maintenance systems, mobile apps for remote monitoring, and third-party IoT platforms (e.g., Alibaba Cloud, Huawei Cloud)—often require the MQTT protocol. This incompatibility prevents real-time data exchange. As a result, key parameters like battery SOC/SOH, PCS efficiency, temperature control status, and fault codes cannot be aggregated in real time on the IoT platform, making remote diagnostics and big data analysis difficult.
To address this challenge, WideIOT deploys a protocol conversion gateway at the energy storage power station site. The gateway connects downstream to IEC104 slave devices, collecting real-time data such as battery SOC/SOH, PCS efficiency, temperature control status, and fault codes. It then converts this data into the standard MQTT protocol and uploads it securely to the IoT platform. This enables the management center to remotely monitor, alert, manage, and analyze data from the remote equipment, helping ensure the safe and reliable operation of the energy storage power station.
Multi-Interface Access and Deep Protocol Parsing
The gateway is equipped with multiple Ethernet ports and RS485/232 serial ports, supporting connections to EMS, PCS, BMS, PV inverters, smart meters, and temperature control units. With a rich library of power industry protocols, the gateway can deeply parse various power protocols such as IEC101/103/104, IEC61850, and Modbus. It also supports protocol conversion to MQTT, HTTP, and OPC UA, effectively breaking down data silos.
Core Conversion: IEC104 to MQTT
As the core of the solution, the gateway standardizes the conversion of IEC104 (TCP/IP-based) into the MQTT protocol. It supports import and flexible configuration of data point tables, allowing users to customize JSON message formats. Telemetry, tele-signaling, and remote control commands are converted into MQTT topics and payloads, enabling seamless integration with various IoT cloud platforms for remote data reading and control operations.
Smart Alerts and Unattended Operation
The gateway features an edge computing rules engine, enabling local logic-based processing of collected data such as battery voltage, temperature, and SOC. When anomalies like abnormal voltage or overheating are detected, the system triggers alerts instantly, pushing notifications (including device model, time, and parameters) via WeChat, SMS, or email, enabling rapid closed-loop resolution.
Industrial-Grade Reliability and Data Retransmission
Built with fully industrial-grade hardware, the gateway supports wide temperature and voltage ranges and is resistant to magnetism and interference—suitable for complex power equipment environments. It includes both hardware and software watchdogs, with features like auto-reconnect on network failure, multi-network backup, anddata caching and retransmission. If the network connection is lost, data is cached locally and automatically retransmitted once the connection is restored, ensuring the integrity and authenticity of power data.
Cloud-Edge Collaboration and Visualized Operations
The platform supports large-screen visual dashboards, displaying real-time device distribution, communication status, charge/discharge power, and energy flow within the energy storage station. Using the multi-source data aggregated through the gateway, the system can automatically generate SOC trend charts, energy efficiency analysis reports, and fault statistics reports, providing a scientific basis for revenue estimation and preventive maintenance of the energy storage station.
