ABOUT

About these examples.

This collection showcases real-world hybrid microgrid SLDs—from remote islands to industrial campuses—to help you visualize architectures, balance loads, and plan your own system.

Whether you're an engineer, project developer, or student, these examples provide a starting point for understanding key components like PV, wind, BESS, diesel gensets, and interconnection schemes.

HOW TO

Make one yourself.

  1. 1

    Define your energy sources and loads

    List all generation (solar, wind, diesel, CHP) and storage (BESS, pumped hydro) assets plus connected loads to establish the system boundary.

  2. 2

    Choose a topology

    Select AC-coupled, DC-coupled, or hybrid bus arrangement based on power flow and control requirements.

  3. 3

    Add protective and metering devices

    Place circuit breakers, disconnect switches, and meters at key points to ensure safety and data collection.

  4. 4

    Edit and annotate your SLD

    Use the drag-and-drop maker to position symbols, label ratings, and customize line styles for clarity.

  5. 5

    Export and share

    Download your diagram as PDF, PNG, or embed interactive version in reports and proposals.

FAQ

Frequently asked questions

What is a hybrid microgrid single-line diagram?01
It's a simplified representation of a microgrid’s electrical system, showing the major components (generators, storage, loads) and their interconnections with a single line, regardless of the actual number of conductors.
Why are hybrid microgrid SLDs important?02
They provide a clear overview of the system architecture, help in protection coordination, and serve as a reference for design, installation, and operation of mixed-source power systems.
Can I use these examples for my project design?03
Yes, you can customize any example using our online maker. Clone the diagram and modify components, ratings, and topology to match your specific hybrid microgrid configuration.
Which standards apply to microgrid SLDs?04
Common standards include IEEE 1547 for interconnection, IEC 61850 for communication, and NEC/NFPA for electrical safety, but the SLD itself is a visual document tailored to your project.
Do these diagrams include protection and control systems?05
Yes, the examples show typical protective devices like breakers and fuses, as well as control interfaces for power management systems, but you may need to add more detail for your specific protection scheme.
