Chapter 271 Power reserve power, about to become regular!
(Reminder in the front row, the next chapter, Chapter 273, is controversial. If you don’t want to read the knowledgeable chapters, skip it directly, and it will not affect reading in general)
Shencheng, Electric Power Monitoring Office of China Southern Power Grid.

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

A man in a suit sorted out the materials at hand, and after confirming the accuracy of the data, he said:
"According to our latest monitoring results, as of June 6, the power load of the power grid in Guangdong Province reached 18 million kilowatts, a month-on-month increase of 1.48%, a record high, and has been rising all the way. So far, our subsidiaries Guangdong, Guizhou, Dian The electricity loads in the five provinces of Guizhou, Guizhou and Qiongxia all set new historical records."

"Following this trend, the demand for electricity will soon exceed the capacity limit of our power grid, especially now that the weather is about to turn hot and the electricity consumption will rise further. Power cuts are in place.”

Hearing his words, the short-haired man sitting in the middle of the meeting room nodded slightly, and then asked:
"Why is there such a severe power shortage this year? Why didn't we foresee this year's peak power consumption when planning the whole year? Is there a problem of insufficient preparation?"

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

"For the peak electricity consumption we are facing now, we really did not anticipate it in advance, but this is not our work mistake."

"In fact, the peak in electricity consumption from the end of April to now was sudden - and it was caused by an unexpected event that we absolutely could not have predicted."

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

"It can be said that this battery changed the power consumption pattern of our entire province almost at the moment of its appearance. Not only did the factory carry out large-scale and high-intensity production for this battery, but after the related products came out, the demand for civilian electricity also increased. rise."

"At present, BYD's charging piles are already overloaded, and new charging piles are still being launched. This situation will intensify after the launch of long-range new energy vehicles from several major manufacturers. At that time, we will face the shortage of electricity supply and demand. The balance is going to get worse."

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

The inch-cut man recorded what the man in the suit said on paper with a pen, and continued to ask:

"Besides this? Is there any other situation that we haven't considered?"

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

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

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

After hearing his words, everyone fell into silence.

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

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

"That's impossible right now we're less than two miles away from where we judge peak power consumption -- no, it's not even a peak value, it's just a critical value where demand exceeds our carrying capacity -- and we're now less than two In a month's time, no matter what we do, it will be too late."

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

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

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

"The power consumption gap of 20% of the load nationwide is a terrible thing."

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

"Is there no other way?"

the inch-haired man asked.

"No really. We will continue to do all the operations we can, but at the same time, we must be clear about a basic principle: the situation we are facing now cannot be solved by our own strength."

"Of course we can cut power, but under the current layout, this is definitely not our best choice."

"This will greatly limit the development of surrounding industries brought about by silicon-sulfur batteries. According to our existing information, the strategic goals carried by this battery are absolutely unshakable. If the strategic layout is delayed due to our problems , the superior will never let us go easily."

"understood."

The inch-headed man nodded, and then continued:
"So, now the situation we are facing and the strategies we need to carry out are basically clear. Xiao Liu, you break down the relevant tasks and distribute them to the responsible persons."

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

"We must not let the power cuts happen in Guangdong Province or in Shencheng. This is the bottom line, and no matter what the price is, we cannot break through the bottom line!"

"understand!"

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 since their careers. This challenge is even more difficult than the power 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, as long as they are not afraid of hardships or difficulties, they can always get through the difficulties.

But now?

What they are facing is a field that is completely foreign to the whole world, and no country has ever faced such a situation.

Therefore, they couldn't find any cases for reference, and they could only rely on themselves.

Then just do your best.

Two hours later, Chen Hao received the news that the power 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 mug. After the two sat down, he said:
"You still need to continue to expand the work of your general technical office. Judging from the current situation, the information gap between the subordinate unit and the superior unit is too great."

"We have been discussing the increase in electricity demand brought about by sulfur-silicon batteries for two months, but the following grid units still don't know anything about our plan."

"This is not a good phenomenon. Look at the report they sent up. They have drawn up a wide range of strategies, and they also involve the cooperation of power grids in multiple provinces and cities. If they really don't cooperate and let them implement it on their own, it will affect our follow-up. The plan has a big impact."

Hearing Ye Zhou's words, Chen Hao nodded.

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

"I will raise this issue at the next meeting, and then relevant experts will discuss it, adjust our information communication and departmental collaboration mechanism, and adapt to the subsequent rapid iteration of technology."

"Now our pace is getting faster and faster, and this acceleration actually happened within a year."

"Although one year is a long time for you and me, for the whole country, there are many people and departments involved, and it is understandable that there is a certain lag."

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

Ye Zhou took a sip of the tea in the cup, and then replied:
"Relax, I can understand, but I still hope that this way of working can be adjusted as soon as possible - even if the most extreme form of promotion is adopted, all personnel must enter the stage of full-speed operation."

"Now that the chariot into the future has started, we need to do our best to leave no one behind."

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

Having said that, Chen Hao paused for a moment, then continued:
"This question is finished, do you have any suggestions on technical matters?"

Ye Zhou pondered for a moment, then shook his head and replied:
"This is not my specialty, just follow your plan. My only request is that there must be no problems in this large-scale grid connection, especially in terms of 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 about this. As long as the high-density battery is solved and the energy storage inverter is online, the entire grid can immediately enter collaborative management."

Chen Hao replied firmly.

Afterwards, the two looked at the lights outside the window in tacit understanding.

Carrying this light is the most advanced power grid system in the world, but 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 current network of this power grid.

The cumulative installed capacity is 305.987GW, the annual installed capacity exceeds 15%, accounting for more than 10% of the total installed capacity of the domestic power grid, but the power generation is limited by the difficulty of grid connection and cannot be increased for a long time. Photovoltaic power grid!
The emergence of high-density battery-configured energy storage inverters has eliminated the last difficulty in photovoltaic grid-connection. The problems of line flow, system protection, power quality and operation scheduling have all been solved. After that, China's power industry will be completely It has entered a period of rapid development.

For this moment, they have been planning for more than 30 years, and everything that happened in these 30 years was a bloody bayonet fight that was a hundred times bloodier than the night march!
