Local EMS - Renon Power Technology Inc.

REAL-TIME INTELLIGENCE AT THE EDGE

Local EMS serves as the on-site control core of the energy storage system,
independently managing real-time power control, safety protection and device coordination without relying on continuous cloud connectivity.

Real-Time Control – Executes power commands and protection actions with millisecond-level response.
Local Autonomy – Continues executing preset strategies when external network connectivity is interrupted.
Safety Priority – Local safety protection logic remains the highest-priority control layer across all conditions.

BUILT FOR REAL-TIME CONTROL

Fast, reliable control from local devices to system-wide energy management.

< 100 ms

Real-Time Control

Millisecond-level execution of charge / discharge power commands, protection actions and related real-time control.

Industrial Protocols

Multi-Device Connectivity

Supports Modbus, CAN, IEC 104 and IEC 61850 for reliable communication with field devices.

Highest Priority

Safety Protection

Core protection logic for conditions such as battery over-temperature and grid abnormalities retains highest execution priority.

< 1 s

Instant Alarming

Monitors device status in real time and triggers local HMI and indicator alarms when abnormal conditions occur.

1-10 Hz

High-Frequency Data Acquisition

Collects voltage, current, SOC, temperature and other operating parameters to support local control and scheduling.

> 72 h

Offline Operation

Core functions remain operational without external network connectivity, with data synchronized after communication is restored.

From Device To Site-Level Coordination

Layered control architecture seamlessly connecting field sensors to site-wide matrix dispatch and remote cloud management.

Local EMS System Layout

Local Safety Override

When a safety condition is triggered, Local EMS overrides all other commands and executes protection actions instantly.

Safety Protection

Millisecond-level response and hardware interlock mechanisms enable rapid fault detection and isolation, helping protect the system and connected equipment from abnormal operating conditions.

Local Control

Local power control and device management enable direct system operation, real-time monitoring, and reliable equipment coordination without relying on cloud connectivity.

Strategy Execution

Energy optimization strategies enable intelligent scheduling, load balancing, and coordinated control to improve overall system efficiency.

External Commands

Receives and executes dispatch commands from cloud platforms and third-party systems for coordinated energy management and remote control.

Open Integration. Local Safety Control.

Open industrial interfaces paired with strict local safety responsibility boundaries.

Designed to Keep RunningAutonomous offline operation with zero data loss upon network recovery.

Normal Operation – Connected to upper layer. Preset energy strategies run as scheduled.
Local Autonomy – Communication interrupted. Local EMS switches to autonomous mode immediately.
Autonomous Operation – Continues executing local strategies and safety protection independently for >72h.
Data Resynchronization – After network recovery, historical data is uploaded and system status is synchronized.

Local Energy Strategies

Standardized on-site strategies designed to optimize electricity costs, maximize self-consumption, and ensure power continuity.

Peak Shaving

Charge during off-peak hours and discharge at peak tariffs.

Demand Management

Cap site peak demand based on configured power thresholds.

Backup Power

Rapid off-grid backup during grid failure or outages.

PV Self-Consumption

Store local PV energy to maximize clean self-use.
