On-Grid Microgrid Energy Storage System

System Overview

The grid-connected microgrid system is a clean energy solution integrating distributed power generation, energy storage, intelligent control, and grid interaction. The microgrid enables bidirectional power flow through a Point of Common Coupling (PCC)—it can draw power from the main grid or feed power back to it.

The system supports both grid-connected and off-grid operation, prioritizing grid connection mode. In the event of a grid outage, it seamlessly switches to off-grid mode, ensuring reliable electricity supply.

Key Advantages

  1. Enhancing Renewable Energy Utilization

    • Stabilizes solar and wind power fluctuations, reducing wasted energy and lowering carbon emissions.

  2. Optimizing Grid Efficiency

    • Peak shaving & load shifting: Charges during low-demand periods and discharges at peak hours, easing pressure on the main grid.

  3. Improving Power Reliability

    • Operates independently during grid failures, preventing widespread outages.

    • The energy storage system provides emergency backup power.

  4. Economic & Policy Benefits

    • Reduces electricity costs (such as peak-valley arbitrage).

    • Supports distributed energy policies and aligns with low-carbon initiatives.

  5. Smart Control

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

Application Scenarios

  1. Industrial Parks

    • Integrates solar + energy storage to optimize corporate electricity costs.

    • Supports high-reliability power needs, such as precision manufacturing.

  2. Commercial Complexes

    • Provides backup power for malls and office buildings, ensuring stability for elevators and data centers.

  3. Residential Communities

    • Uses rooftop solar + energy storage to reduce community energy consumption.

    • Ensures essential electricity supply during disasters.

  4. Remote Areas

    • Leverages local solar and wind resources, reducing dependence on long-distance power transmission.

    • Lowers electricity costs in off-grid locations.
