“How can we use voltage reduction to help the duck curve?”

 

The duck curve is one of the most pressing issues in renewable energy integration. However, most methods to ameliorate this are usually quite complicated. But how can we use our engineering mindsets to solve this problem? Well, we know that if we were to reduce the voltage that an appliance uses, then its power dissipation will go down. So what if we were to have an automated system where this will occur during peak energy use times? This is the idea behind Voltage Reduction for the Duck Curve and holds a promising future for demand response regulation.

“How can we use energy storage to ensure grid reliability?”
One of the largest challenges facing grid integration is the infamous duck curve. The enormous spike up in electricity during times of low energy generation can wreck pure havoc on the grid. However, how can we use our engineering mindset to solve this problem? Well, what if we were to store excess energy generated, and withdraw it during times of need? This way, we can use Energy Storage for Grid Frequency Regulation!

“How can we turn energy storage into a business?”

 

Traditionally, facilities had only two options for receiving electricity, generating their own or purchasing from a utility. But with the advent of renewable energy and advanced energy storage, this picture is starting to change. Facilities can now enter contracts with organizations to receive energy from energy storage systems. This venture known as Energy Storage as a Service has the potential to generate revenue, create savings, and improve electricity resiliency by providing clean energy at affordable rates

“How can we make sure that buttons on a microcontroller work?”

 

Microcontrollers are the backbone of modern-day mechatronics systems. However, the default circuitry has a serious problem. When a button is not pressed, the input automatically reads ground. This can cause serious misreadings to happen, which can cause the microcontroller to crash! So how can we use our engineering mindset to solve this problem? Well, what if we were to simply add a resistor to the input voltage? This way, when the switch is grounded, we can have the system read “High” instead of ground!

“What happens when there is an unintentional drop in electric voltage in a power supply system?”

 

What roads were to Rome the electric grid is to modern civilization. Like a heart pumping blood to the rest of the body, the grid ensures that every component receives enough vital supplies. But sometimes, there is not enough voltage to go around, and as a result components will need to take a drop in voltage. This phenomenon is known as a brownout, and can lead to unexpected results like all of the lights in the city dimming down or space heaters losing their practical functionality.

“Does implementing distributed energy resources and national security go hand in hand?”

 

It is usually thought that renewable energy sources such as solar and wind cause danger onto communities due to their lack of centralization. However, can this feature actually be a security advantage? Well, it turns out that by having energy generation be distributed instead of in a centralized location like a power plant, the grid becomes less prone to attacks and can recuperate much faster in case of such an event. Therefore, Distributed Energy Resources actually help national security!
