A microgrid is a small scale electricity grid that can operate independently from the main power grid. It is typically used to provide power to a small community or a single building, and it can incorporate a variety of different energy sources, such as solar panels, wind turbines, and fossil fuel generators. It can utilize battery storage to add to the Microgrid’s resiliency.
There are several different types of microgrids each with its own unique characteristics and applications.
One type of microgrid is the stand alone microgrid which is not connected to the main power grid. These systems are often used in remote or off-grid locations, such as remote villages or military bases. Stand alone microgrids typically rely on renewable energy sources, such as solar and wind power, to generate electricity.
Another type of microgrid is the utility grid connected microgrid, which is connected to the main power grid. These systems can operate independently from the main grid, but they can also sell excess energy back to the grid via net metering or draw power from the grid when needed. Grid connected microgrids are often used in urban areas, and they can incorporate a variety of energy sources, including renewable and non-renewable sources.
A third type of microgrid is the virtual microgrid, which is a group of distributed energy resources (DERs) that are connected and controlled via advanced technologies. Virtual microgrids can help improve the reliability and resilience of the main power grid by providing backup power during outages, peak demand and they can also help to optimize the use of renewable energy sources.
Overall, microgrids are becoming increasingly popular as a way to provide reliable, clean, and resilient power to communities, utilities businesses and buildings. By incorporating a variety of energy sources and advanced technologies, microgrids can help to reduce the reliance on fossil fuels and support the transition to a more sustainable energy future.
