On unusual days, the importance of energy storage in the grid may not be an ordinary day.
Maybe a tree fell on the wire, or lightning hit it.
These interruptions will reduce the voltage of the line to the desired level.
The voltage change causes the computer to reset.
Now your alarm clock is flashing at 12: 00.
Or worse: "For all automated manufacturing processes, it shuts down the process if the computer resets.
"If you are a plastic manufacturer and your machine cools down, the plastic will solidify in your machine," Boyes said . ".
What if the events of the day exceeded the efforts of the utility to compensate?
Yes, you guessed it. -
You're going to have a power outage.
It did happen throughout the Northeast in 2003.
With the chaos of the grid, it is hard to imagine adding more renewable sources, such as wind and solar, because they are intermittent sources of energy.
We know that customers are unpredictable, but power is unpredictable now.
When the wind suddenly disappears, a wind farm loses 1,000 MW in a few minutes, and then has to buy and import power quickly for customers.
Then another option is to use peaker-style fossil-
But this increases the air pollution of clean electricity.
Or rule naturally.
In the Texas wind farm, when demand is low, the wind blows almost only at night, and the price of electricity becomes negative.
"That means you have to pay the electricity bill for the grid," said Gyuk . ".
"I talked to a guy who had the air conditioner on all night because he got the air conditioner for free.
Then he closed the window.
"According to Gyuk, these problems will worsen as we use more electronics and more electricity.
So what are the answers to these questions?
Power grid energy storage.
Before we dive into this topic, it is important to understand the meaning of storing energy.
The work of the grid is to supply power to each customer at a voltage of 120 V and 60Hz.
This is done by adding or removing current from the grid.
Storage devices help by adding or removing current when needed.
Read on and learn how energy storage can strengthen the grid.
