Smart Microgrid System

Achieve stable power supply and energy efficiency optimization in the local power grid

Industry Overview

Power Transmission Solutions

The overall solution for hydrogen refueling stations constitutes a specialized integration system of engineering technologies. At its core is the establishment of a complete, efficient, and highly reliable technical chain for hydrogen handling, encompassing the stages of reception/preparation, purification, compression, storage, and refueling. This system typically comprises four principal subsystems: the front-end hydrogen supply module (comprising gas unloading units or on-site hydrogen generation systems such as electrolyzers or reformers), the high-pressure processing unit (including compressors, sequence control panels, and high-pressure hydrogen storage arrays), the refueling terminal (featuring pre-cooling units and hydrogen dispensers), and the integrated station control and safety management system.

Industry Challenges

Harsh Marine Environments

Resisting extreme water pressure and chemical corrosion over a 30-year lifespan.

Installation Complexity

Precision laying in varied seabed terrains to avoid mechanical damage.

Transmission Loss

Minimizing energy dissipation during long-distance underwater delivery.

Our Solution

Smart Microgrid System
 
To address the four major energy challenges faced by mines—remote locations, high energy costs, unstable power supply, and high emissions—we propose a smart microgrid solution for mines. This solution consists of five key components: power generation, energy storage, load, control and management, and power distribution and protection. At its core is the control and management unit, which coordinates the collaborative operation of photovoltaic systems, energy storage, and diesel generators to achieve optimal system performance and the lowest possible costs.

Battery Energy Storage Systems

Our grid-side BESS provide essential capacity and energy flexibility. By accurately forecasting renewable generation and grid demand patterns, our advanced energy management system strategically schedules charging during periods of surplus clean energy and discharging during peak demand hours. This intelligent time-shifting capability transforms intermittent renewable power into dispatchable capacity, effectively flattening the grid's load curve, reducing reliance on fossil-fueled peaking plants, and supporting the deferral of transmission infrastructure investments.
