After reading the information above, the most obvious question must come to mind: why do we need microgrids? Well, we are here to explain the same to you.
Currently, we use fossil fuels as a source of energy. It is no secret that we need to stop doing that because sooner (or later), we will run out of those resources. Microgrids are a solution to this problem. With the help of microgrids, we can use solar energy for our day-to-day activities.
This will certainly help us in making the environment reach the point of sustainability. Furthermore, microgrids help us reduce the cost of electricity that we currently use. The cost of energy and electricity reduces substantially if we use the energy from the sun.
Additionally, we can even store this energy from the sun in storage banks such as batteries. Microgrids can operate on batteries when the central grid is out of power. Many business owners are opting for microgrids because they reduce the overhead costs entirely.
Microgrids undoubtedly contribute to the economic growth of any area where they are utilized while reducing the carbon footprint and lowering CO2 emissions. It is safe to say that microgrids are the best option to move towards sustainability.
Where Are Microgrids Used?
Microgrids have several applications due to the advantages they offer. Now, you must be curious about where we can use microgrids. Below we have collated a list of applications of microgrids.
- Military bases
- Emergency response buildings
What Are The Different Types Of Microgrids?
As you saw previously, microgrids have a variety of applications. As patterns in the market and technology continue to change, types of microgrids continue to evolve. Take a look at the types of microgrids that are currently available and being used:
These microgrids are typically used in corporate campuses, military campuses, or university campuses. They generally offer combined heat and power (CHP). Their main purpose is to accumulate existing renewable energy and allow easy management.
As the name suggests, island microgrids are being used in islands to incorporate renewable energy as power systems. Additionally, islands worldwide are trying to inculcate the practice of energy storage into their respective energy systems.
One of the most critical objectives for any defense system is to ensure that they can rely on energy and have energy storage for a crisis. So, reliance on diesel fuel is not the best way to go in today’s world. The costs are high, and transportation is challenging. To combat this, more and more military bases are using microgrids to increase stability, efficiency, and reliability.
In some parts of the world, microgrids are helping achieve electrification for the first time in different communities. Microgrids have helped reach renewable energy targets and sustainability goals in other parts of the world. Therefore, the number of communities relying on microgrids has increased as microgrids result in fewer power outages due to the stored energy systems.
Remote microgrids are responsible for providing access to energy in areas that are beyond the grid. Earlier, diesel was used to fuel such areas. However, with the popularity and affordability of renewable energy, microgrids have come into the picture.
What Are The Benefits Of Microgrids?
As you can see, microgrids have a wide range of applications. Microgrids offer features that you can’t miss – which is why they are on the rise. Here are the five impressive benefits of microgrids that we have put together for you!
Reduction of fuel usage
Although microgrids offer highly efficient power, they still reduce fuel use and substantially cut down the carbon footprint. Additionally, they also lead to lowering line losses.
High energy reliability
As we mentioned above, microgrids come with different forms of distributed energy. They do not require any above-ground wires. This results in enhanced energy reliability. So, whenever there is a power outage, you can rely on the microgrid for power.
Microgrids come with energy storage systems that make it easier for you to utilize and manage renewable energy before you get more of it. They are a perfect and the most suitable support for renewable energy generation.
As renewable energy prices are on the decrease, microgrids come at a surprisingly low price. Furthermore, as these systems come with stored energy, you will cut down on the cost of extra power that you need during power outages.
Great energy delivery
Microgrids are known to offer you fewer interruptions, lower-cost, efficient and clean energy. This is also followed by less variability.
How Do Microgrids Work?
To understand the functioning of a microgrid, you will have to know how the grid works in totality. The grid is responsible for connecting buildings, homes, and businesses to the central power sources.
This connection enables us to use the appliances, electronics, and cooling or heating systems at our respective locations. However, being connected to a single grid also means that all connected users are affected whenever one part of the grid needs maintenance.
This is where a microgrid comes into the picture. A microgrid is also connected to the central power grid. However, a microgrid can break away from this central grid and operate single-handedly with the help of a stored energy system.
This feature is beneficial in times of power outages, storms, or situations where the central grid needs to be repaired. As discussed earlier, a microgrid comes with distributed forms of energy through batteries, generators, solar panels, and wind turbines.
So, yes! A microgrid can run indefinitely if it is powered from a source that relies solely on renewable energy.
