Microgrids have the ability to provide independent electricity to local areas such as hospitals, military bases, etc., without relying on the national grid. This technology is gradually becoming popular due to the widespread application of solar energy in current production. However, do you fully understand what a Microgrid is? How will this technology change the way we use energy? Let’s explore this through the below article.

1. What is a Microgrid?

A Microgrid system is a self-sufficient electrical energy system that can manage distributed energy sources, including renewable energies (solar, wind, hydro, etc.) and non-renewable sources. This system can operate independently or connect to the main power grid, providing flexibility and autonomy in electricity supply. Solar energy is one of the important renewable energy sources that is often integrated into Microgrid systems.

Components of a solar energy microgrid system:

• Solar Panels: Solar panels are responsible for converting sunlight into electrical energy.
• Maximum Power Point Tracking (MPPT) System: This technology ensures that the panel’s performance is always maximized, regardless of the connected load.
• Energy Storage System: This helps store the electrical energy generated from the solar panels and provides power for use in necessary situations (when there is no sunlight).
• Inverter: Inverters convert direct current (DC) into alternating current (AC) to supply power to household appliances.
• Control and Monitoring System: This system manages and optimizes the operations of the microgrid, including monitoring production, distribution, and electricity usage.

2. Operating principles of the solar energy Microgrid system:

Electricity generation: Solar panels convert sunlight into electrical energy.

Storage: The generated electrical energy is stored in the energy storage system (ESS).

Power supply: The electrical energy from the storage system is converted into alternating current through an inverter and supplied to the load (factories, enterprises, etc.).

Grid connection: The Microgrid can operate independently or connect to the national power grid. When connected to the common grid, the facility can sell excess solar electricity back to the grid.

Island mode: When the public grid experiences issues (power outages, cable breaks, etc.), the Microgrid can switch to independent mode to ensure continuous power supply.
