Off-Grid Microgrid Energy Storage System

System Overview

The off-grid microgrid system integrates distributed power generation, energy storage, and intelligent control to create a self-sustaining power network. It operates independently from the main grid, using internal energy management to provide self-sufficient electricity.

  • Primary functions: self-generation, power balancing, and ensuring reliable energy supply in areas without grid coverage or where grid extension is difficult.

  • When renewable energy sources (e.g., solar power) are available, they prioritize supplying the load, with excess energy stored in the energy storage system.

  • When renewable generation is unavailable, the storage system provides power, ensuring a stable electricity supply.

Key Advantages

  1. Independent Power Supply

    • Operates without relying on the main grid.

    • Utilizes local distributed energy sources (e.g., solar and wind power) to ensure reliable electricity for remote areas like islands, mountains, and border zones.

  2. High Reliability & Resilience

    • The storage system stabilizes renewable energy fluctuations, ensuring continuous power supply on cloudy days or at night.

    • During extreme events (e.g., typhoons or earthquakes), the off-grid microgrid operates autonomously, ensuring electricity for critical facilities such as hospitals and communication stations.

  3. Economic Benefits

    • Significantly reduces fuel costs over long-term operation.

  4. Smart Control

    • The EMS system enables automatic scheduling, reducing maintenance complexity.

Application Scenarios

  1. Power Supply for Remote Areas

    • Ideal for locations without grid coverage, such as mountains, pastoral areas, and islands.

    • A solar + storage + diesel generator solution ensures 24-hour electricity supply.

  2. Telecommunication Base Stations

    • Ensures uninterrupted operation of critical telecom infrastructure, reducing reliance on diesel generators.

    • A solar + energy storage solution prioritizes power for communication equipment through smart scheduling.

  3. Emergency Power Supply

    • Suitable for disaster relief, temporary construction sites, and other short-term power needs.

    • Containerized off-grid solar-storage systems offer a plug-and-play solution for rapid deployment.
