How to Properly Use Distributed Energy Resources for Resilience

“How should we use distributed energy resources to build resilience?”

Distributed energy resources such as solar and wind energy are shaping up to be the next dominant paradigm in energy. And one of their most touted benefits is the increased resilience that they will bring. However, research has shown that this will only occur if they are deployed in a careful manner. This means that they will need to be planned to provide backup to vulnerable transmission lines, relieve congestion, and be placed under control of grid operators. This is How to Use Distributed Energy Resources for Resilience.

“How can we increase security by making the grid go offline?”

In the modern world, it seems like everything is becoming connected to the internet. Although this has brought revolutions in communication, it has also left many components viable to a cyber attack. The grid is no different, and has already been hacked because of this. To prevent this from happening, the grid can simply be disconnected from the internet. That way no attacker can come in and tinker with the components. This is How Isolating Grid Infrastructure from the Internet can Increase Resilience to a Cyber Attack.

“Why should we be able to store energy for months?”

Energy storage is the biggest bottleneck in the deployment of renewable energy. Not only are we currently limited in the amount we can store, but also the time, as decay occurs the longer it is stored. And with the deeper penetration of renewables, energy will have to be stored for longer durations, so that charge can be stored during the sunny summer months and extracted in the dark winter ones. This is Why Seasonal Energy Storage is Necessary for Large-Scale Penetration of Renewables.

“How can we describe the power output density capability of a particular device?”

Power supply is one of the foundations of modern technology. But some devices can supply more power than others. The amount of power that can be supplied by one mass unit of a material is known as the Power Density. In batteries, power density is usually contingent on the current output as voltage is typically held constant.

“How could hot areas become more resilient by trimming trees?”

Electrical transmission lines can fault for a variety of reasons. But one of the most common is from being near untrimmed trees. These can fall onto the power lines, causing power disruption. In the case of extreme drought, static buildup can even rupture a fire, as seen in the 2018 Northern Californian Camp Fire. To prevent this, we can simply trim the trees. This allows for increased safety against extreme weather. This is How Trimming Trees Near Transmission Lines Could Increase Infrastructure Resilience in Drought-ridden Areas.

Quantum Dots for Solar Panels

“Why are quantum dots for solar panels so useful?”

 

Quantum dots are bringing a revolution into the world of semiconductors. And since semiconductors are the backbones of solar panels, things will be greatly changed for them as well. The extra emissivity offered by quantum dots means that two and possibly three electrons can be generated for every photon received, vastly increasing its potential! Quantum dot solar panels can achieve as much as 65% efficiency, nearly double of the theoretical limit of normal panels. This is why Quantum Dots for Solar Panels are so exciting.
