6 FAQs about [Relationship between large power grid and microgrid]

Why do we need a smart grid and a microgrid?

The competitive landscape among energy providers and distributors has empowered consumers to not only save money on their energy bills but also incorporate sustainable energy sources into the grid. To efficiently manage electricity distribution, deregulated power systems must include a smart grid and microgrid (MG).

What are microgrids & how do they work?

Microgrids are localized electric grids that can disconnect from the main grid to operate autonomously. Because they can operate while the main grid is down, microgrids can strengthen grid resilience, help mitigate grid disturbances, and function as a grid resource for faster system response and recovery.

What happens if a microgrid is grid-connected?

If the microgrid is grid-connected (i.e., connected to the main electric grid), then the community can draw power from the main electric grid to supplement its own generation as needed or sell power back to the main electric grid when it is generating excess power.

Are microgrids the future of energy?

Microgrids can be deployed in a variety of sizes and locations from a single building to an entire municipality. Regardless of what name these grid types go by, each has an important place in our energy future. And when used jointly as part of a broad, interconnected energy system, we all reap the benefits.

What is the difference between a microgrid and a generator?

While traditional generators are connected to the high-voltage transmission grid, DER are connected to the lower-voltage distribution grid, like residences and businesses are. Microgrids are localized electric grids that can disconnect from the main grid to operate autonomously.

How does microgrid deployment affect energy distribution?

As the Navigant Research deployment tracker shows, microgrid deployment continues to rise in markets around the world contributing to a more decentralized energy distribution model.While mature energy economies look to modernize their infrastructure and provide more resilient energy, emerging economies are looking for access to reliable energy.
