Composite Peak-Valley Arbitrage and Demand Management

AI-EMS can coordinate the load curves of industrial parks and charging stations, charging energy storage during off-peak electricity rates or photovoltaic peak periods, and discharging when both the park and charging stations experience peak electricity rates. This achieves dual arbitrage while more effectively smoothing overall peak loads in the park and reducing total demand charges.

Maximizing Distributed PV Value

PV systems supply power for production and office use. Excess electricity is prioritized for storage in energy storage systems or for charging stations within/near the campus. This transforms green power that might otherwise be sold at low rates into high-value charging services or production electricity, significantly boosting PV self-consumption rates and overall returns.

Alleviating Distribution Grid Expansion Pressure

Through AI-EMS coordinated control of “PV-storage-charging-load,” charging power and timing can be actively managed to prevent overlapping charging peaks with industrial production, mitigating distribution grid impacts and delaying or avoiding costly grid expansion investments.

Enhancing Power Supply Reliability

The energy storage system serves as a shared backup power source for the industrial park and charging stations, ensuring critical production loads or emergency charging services remain powered during grid failures.

PV Power Supply

PV panels are installed using spaces such as carports and rooftops to provide clean electricity for charging stations, reducing dependence on grid utility power.

Energy Storage Buffering

Energy storage units are equipped to store surplus PV power, which supplies electricity to charging stations during peak power consumption periods or when PV output is insufficient, avoiding grid overload.

Intelligent Dispatch

Collaborative control of PV, energy storage and charging stations is realized through a cloud platform, supporting time-of-use (TOU) electricity price strategies and V2G (Vehicle-to-Grid) functionality, improving energy utilization efficiency.

Independent Grid-Forming Capability Ensures System Stability and Power Quality

Unlike traditional diesel-storage systems that merely function as “load followers,” Engley’s DOP system possesBESSes independent grid-forming capability. Even when all diesel generators are shut down or malfunctioning, the system can independently establish and maintain stable voltage and frequency through energy storage, delivering high-quality, uninterrupted power to critical loads. This fundamentally ensures power supply reliability under extreme conditions.
