Shencheng, China Southern Power Grid Power Monitoring Room.

All the core members of the power grid monitoring team gathered in front of the big screen, frowning as they looked at the data displayed on the screen.

A man in a suit sorted out the materials at hand, and after finally confirming that the data was accurate, he said:

"According to our latest monitoring results, as of June 18, the power load of the Guangdong Province power grid reached 148 million kilowatts, an increase of 3.3% month-on-month, a record high, and rising all the way. So far, our subsidiaries in Guangdong, Guangxi, and Dian The electricity load in the five provinces of Guizhou, Guizhou and Qiong has all set new historical records."

"If this trend continues, the demand for electricity will soon exceed the carrying limit of our power grid. Especially now that the weather is about to get hotter, electricity consumption will rise further. It is expected that by mid-July, we will have to resort to turning off the power grid. Power rationing measures are in place.”

Hearing his words, the short-haired man sitting in the middle of the conference room nodded slightly, and then asked:

"Why is there such a serious power shortage this year? Why didn't we foresee this year's peak power consumption when we were planning for the year? Is there a lack of preparation?"

The man in the suit sighed helplessly, and then pressed the remote control in his hand, and the large screen switched to the presentation document screen he had prepared in advance.

"We did not anticipate the peak power consumption we are facing now, but this is not a fault of our work."

"In fact, the peak electricity consumption from the end of April to now occurred suddenly - and was caused by an unexpected event that we absolutely could not foresee."

"That is, the sulfur silicon battery developed under the leadership of the General Technical Office."

"It can be said that this battery changed the electricity consumption pattern of our entire province almost as soon as it appeared. Not only did the factory carry out large-scale and high-intensity production for this battery, but after the introduction of related products, civilian electricity demand also increased. rise."

"At present, BYD's charging piles are already overloaded, and new charging piles are constantly being launched. This situation will intensify after the long-range new energy vehicles of several major manufacturers are launched. By then, we will face a shortage of electricity supply and demand. The balance situation will be more serious."

"Although this effect has not yet fully emerged, we must prepare early."

The short-haired man wrote down what the man in the suit said with a pen on the paper while continuing to ask:

"Apart from this? Are there any other situations that we haven't considered?"

"I have also learned about the silicon-sulfur battery project. I personally believe that the impact of this battery is far beyond that."

"According to the public information we have obtained, the current application of this battery in the military field may far exceed the civilian field, so the increase in power demand it brings is far beyond what we can predict."

"So, before we receive official notification, we must prepare in advance - at least prepare with a 20% load margin."

After hearing his words, everyone fell silent.

For a stable operation of the power grid system, increasing the load by 20% is far from being as simple as it seems on the surface. The various grid connection and peak shaving operations it needs to design are almost impossible for any country to complete. operation.

After a long time, the man in suit said hesitantly:

"This is impossible. We are now less than two kilometers away from the peak of electricity consumption that we judged - no, this is not even a peak, it is just the critical value where the demand for electricity exceeds our carrying capacity. Months of time, no matter what we do, it’s already too late.”

"We do have a fourth-generation reactor power station under construction, but it is still far from being connected to the grid. In a short period of time, water from far away will not be able to quench the thirst of nearby people."

"In addition, even if we mobilize the national power grid and transfer power from other provinces, cities and regions, there is no way to make up for this gap."

"More importantly, in the future, not only we will face power shortages, but this situation will gradually spread to the whole country. By then, I am afraid that the whole country will face the same situation."

"There is a power shortage of 20% of the load across the country. This is a terrible thing."

"So, I personally think that this is not a problem that we can solve. We should report it to the superior unit immediately, explain the situation in a timely manner, and make overall arrangements."

"Is there no other way?"

The short-haired man asked.

"It's really gone. We will continue to do all the operations we can, but at the same time, we must make a basic principle clear: the situation we are facing now is absolutely impossible to solve on our own."

"Of course we can impose power cuts, but under the current layout, this is definitely not our best option."

"This will greatly limit the development of peripheral industries brought by silicon-sulfur batteries. According to the information we have, the strategic goals carried by this battery are absolutely unshakable. If the strategic layout is slowed down due to our problems, , the superiors will never let us off easily."

"Understood."

The short-haired man nodded and continued:

"So, now the situation we are facing and the strategies we need to carry out are basically clear. Xiao Liu, please break down the relevant tasks and assign them to each responsible person."

"The company immediately launched an emergency response plan. In the next two months, all our work will be centered on this goal."

"We absolutely cannot allow power outages to happen in Guangdong Province or Shenzhen. This is the bottom line, a bottom line that cannot be exceeded no matter what the cost!"

"clear!"

Everyone in the monitoring room answered in unison, and then immediately got into intense work.

Everyone knows that what they are about to face is probably the biggest challenge they have ever faced in the industry. This challenge is even more difficult than the electricity shortage caused by the ice and snow disaster, because at that time, they at least knew what to do. At least they can still be sure that as long as they invest manpower and material resources regardless of the cost, and as long as they are not afraid of hardships and difficulties, they can always overcome the difficulties.

But now?

What they are facing is an area that is completely unfamiliar to the entire world. No country has ever faced this situation.

Therefore, they could not find any cases for reference and had to rely on themselves.

Then you have to try your best.

Two hours later, Chen Hao received the news that the electrical load was about to reach its limit, but neither he nor Ye Zhou felt anxious about it.

In the living room, Ye Zhou handed Chen Hao a cup of Tieguanyin brewed in a large tea vat. After the two sat down, he said:

"The work of your General Technical Office still needs to continue to expand. Judging from the current situation, the information gap between lower-level units and higher-level units is too big."

"We have been discussing the increase in electricity demand caused by sulfur-silicon batteries for two months, but the power grid units below still know nothing about our plans."

"This is not a good phenomenon. If you look at the report they submitted, the strategy they formulated is very broad and involves the cooperation of multiple provincial and municipal power grids. If there is really no cooperation and let them implement it on their own, it will be very difficult for us in the future. The plan has a great impact.”

Hearing Ye Zhou's words, Chen Hao nodded.

"This is indeed a big problem. I remember that we have encountered this problem before during the chip project, and now this is the second time it has appeared."

"I will raise this issue at the next meeting, and then relevant experts will discuss it and make adjustments to our information transmission and department collaboration mechanisms to adapt to subsequent rapid technology iteration needs."

"Now we are getting faster and faster, and this acceleration actually happens within one year."

"Although one year is a long time for you and me, for the entire country, with so many people and departments involved, it is understandable that there will be a certain lag."

"So, I still hope you can understand this."

Ye Zhou took a sip of the tea in the cup and then replied:

"Don't worry, I understand, but I still hope that this way of working can be adjusted as soon as possible - even if the most extreme form of salary increase is adopted, all personnel must be put into full operation."

"Now, the chariot to the future has started, and we need to do our best not to leave anyone behind."

"Understood, I will report it to my superiors."

Having said this, Chen Hao paused for a moment, and then continued:

"Having said this question, do you have any suggestions on technical matters?"

Ye Zhou pondered for a moment, shook his head and replied:

"This is not my specialty, so just follow your plan. My only requirement is that there must be no problems with this large-scale grid connection, especially with key equipment - energy storage inverters are not It’s a new product, and now it’s difficult to solve the problem of high-density batteries. If there is a problem with this, I really can’t understand it.”

"No, we are confident in this aspect. As soon as the high-density batteries are solved and the energy storage inverter comes online, the entire power grid can immediately enter coordinated management."

Chen Hao replied firmly.

Then, the two of them looked at the lights outside the window in tacit understanding.

Carrying this light is the world's most advanced power grid system, and now, this power grid system is facing huge challenges.

However, this does not make them uneasy.

Because there is a huge reserve power hidden outside the existing power grid.

The cumulative installed capacity is 305.987GW, the annual newly installed capacity is more than 15%, and it accounts for more than 10% of the total installed capacity of the domestic power grid. However, the power generation capacity is limited by the difficulty of grid connection and has been unable to increase. Photovoltaic power grid!

The emergence of high-density battery-equipped energy storage inverters has eliminated the last difficulty of photovoltaic grid connection. Line power flow problems, system protection problems, power quality and operation scheduling problems have all been solved. After this, China's power industry will be completely Entering into a period of rapid development.

They have been planning for this moment for more than 30 years, and what happened in these 30 years was a brutal fight with red bayonets that was a hundred times bloodier than a march in the dark!
