Nanshan Group was not involved in the wind power business at all, so the various business divisions within the group did not focus on wind power.

However, during this period of time, the research and development of wind power bearings has naturally attracted the attention of some people.

In particular, the information of Fan Huabo and others from Modu Electric Appliances who came to visit was also reported on the intranet of Nanshan Group.

As a result, more people are paying attention to wind power.

And this pondering really made some business departments come up with some interesting solutions.

The first report Cao Yang heard after going to work today was that Lin Cheng of Nanshan Battery came to report to him on the innovative topic of combining wind power equipment and Nanshan battery business.

"For the development of a country, the importance of energy supply is self-evident."

"Wind power is a clean energy that uses the kinetic energy of the wind to convert it into electricity."

"Compared to traditional fossil fuel power generation, wind power generation does not produce harmful gases such as carbon dioxide, sulfur dioxide and nitrogen oxides, and does not cause further pollution to the atmosphere."

"It's very important to reduce air pollution and improve air quality."

"Its benefits are not only in reducing dependence on fossil fuels, but also in demonstrating the advantages of renewable energy, which is important for protecting the environment and mitigating climate change."

"Therefore, wind power has also become another important energy source after coal and oil, and has been highly valued by many countries."

"However, as it spreads, some of the worrying hazards that lurk behind it are gradually emerging."

"Due to the instability of wind power, even in the case of sufficient wind resources, there are certain difficulties and challenges in grid access, and the power generation of wind power will be affected by factors such as wind speed and wind direction, which may lead to the instability and unreliability of wind power generation."

"With the increase of the capacity of wind turbines, the impact on the grid will be greater when they are connected to the grid."

"When this kind of impact is severe, it not only causes a large drop in the voltage of the power system, but also may cause damage to the generator and mechanical parts, such as towers, propellers, speed increasers, etc."

"If the grid-connected shock lasts for too long, it may also cause the system to collapse or threaten the normal operation of other grid-connected units."

"What's more serious is that the long-term grid-connected impact will even cause the disconnection of the power system and threaten the normal operation of other generator sets."

"For this problem, at present, the grid-connected inrush current is suppressed through reasonable generator grid-connected technology, but I think that no matter how the technology is improved, the shortcoming of wind power instability will always exist."

Along with Lin Cheng's explanation, Cao Yang also had a concept in his heart.

This is indeed a problem.

Grid power transmission is a complex issue.

The output of traditional power stations is relatively stable, or controllable.

But wind power is different, when the wind is strong and when the wind is small, this is not a human decision at all.

This is the industry of watching God eat.

And realizing this problem, without waiting for Lin Cheng to continue, Cao Yang could guess what he wanted to say.

"Nanshan Battery wants to do energy storage business?"

As soon as Cao Yang said this, Lin Cheng's eyes immediately lit up.

The boss immediately broke the core spirit of his own reporting materials, so the possibility of this matter being worth doing has greatly increased.

"Yes, the power quality of wind power is relatively low, and the harm of direct grid connection is relatively large."

"But if the wind power is stored through the energy storage station through the energy storage station, and then the output is regularly connected to the grid, then this problem can be alleviated to a great extent."

Lin Cheng's explanation, Cao Yang naturally understood.

However, the professional terms that pop up from time to time are just to understand the words, but not the meaning.

If you don't understand, just ask, Cao Yang is not worried that he will lose face like this.

"Does low power quality mean unstable?"

The energy storage business is a big project, and Cao Yang must figure out the situation before judging whether to officially enter this field.

"The power quality indicators of the power system mainly include voltage and frequency deviation, voltage fluctuation, voltage flicker and harmonic problems."

"From the current point of view, the wind power system has a greater impact on power quality is the voltage fluctuation and flicker and harmonic problems."

"Due to the randomness, intermittency and instability of wind energy, the wind speed and wind direction often change, which directly affects the operating conditions of the entire wind power generation system, making the output power of the wind turbine fluctuate."

"Under some extreme working conditions, the entire wind farm will be collectively decoupled from the grid, which will have a very large impact on the power grid."

"All of the above factors are prone to voltage fluctuations and flicker in the grid."

"At present, almost all wind power systems use power electronic converters to realize the power conversion and control functions of wind turbines, but the resulting problem is the harmonic pollution of power electronic equipment to the power grid and the possible resonance."

"Excessive harmonic injection will affect the stable operation of the electrical load, which may lead to the heating or even burning of the equipment."

What Lin Cheng said was somewhat professional, but Cao Yang didn't fully understand.

But the general meaning is understood.

"That is, the electricity generated by wind turbines, the power quality is low, will it bring a rush to the power grid?"

Cao Yang summed it up according to his own understanding.

"Yes, this impact is not only a problem of low power quality, but also related to the structure and stability of the entire power grid."

"For traditional constant-speed wind turbines, because they will absorb reactive power while emitting active power to the grid, the operation of wind farms is overly dependent on system reactive power compensation, which limits the flexibility of grid operation, so it may lead to the instability of grid voltage."

"Now it has become the mainstream of the domestic variable-speed constant-frequency doubly-fed unit due to the use of active and reactive power decoupling control technology, should have a certain output power factor adjustment ability, but at present, it seems that this function has not been effectively used in the wind field monitoring system in China, and the reactive power regulation ability of the wind turbine itself is limited, so it still has a certain impact on voltage stability."

"The intermittent and random nature of wind power further increases the potential risk of stable operation of the power grid."

"In addition, wind turbines may not be able to re-establish the terminal voltage after a system failure, and lose stability, thus causing damage to the voltage stability of the regional power grid."

"In addition to that, there is a big issue that is very important for our energy storage business."

"That's the consumption of wind power."

Lin Cheng, as the general manager of Nanshan Battery, is an expert in power himself.

So he studied the situation of wind power a little, and his understanding was many levels deeper than Cao Yang's.

The most important thing is that he can keenly find business opportunities in the process of understanding.

It's not easy.

There are now many battery manufacturers in the whole of China, but Cao Yang has not heard of anyone who focuses on the energy storage business.

"The areas with the most abundant wind energy resources in China are mainly distributed in the 'three north and one south' region, that is, the northeast, northwest, north and southeast coasts, most of which are at the end of the power grid and far away from the load center."

"After large-scale access, a large number of wind power will be connected to the Internet during the boom period, the power grid transmission power will increase, the number of heavy-load operating lines will increase, and the problem of thermal stability will gradually become prominent."

"With the expansion of the scale of wind power development, the problem of the consumption of electricity generated by it will become increasingly prominent."

"In view of the fact that most wind farms in China are currently planned on the basis of the original power grid, the interstitial nature of wind energy will inevitably lead to problems in the balance between power supply and demand, and then generate unnecessary opportunity costs."

"In order to balance the deviation between power generation and consumption, power needs to be balanced."

"The demand for balanced power grows in tandem with the increase in wind farm capacity."

"Depending on the rules set by different countries, either the wind farm owner or the grid operator is responsible for providing balanced power."

"Once the transmission system dispatcher signs up with it, it will be part of the entire grid tax and will be borne by all consumers."

"The integration of wind power to the grid increases the difficulty of peak regulation and frequency regulation, and the intermittent and random nature of wind power increases the burden of frequency regulation of the power grid."

"Wind farms are unstable energy sources, which are greatly affected by wind power and wind turbine control systems, especially the problem that wind farms may output very little during peak load periods and large output during non-peak load periods, and the anti-peak regulation characteristics of wind power increase the difficulty of peak regulation of the power grid."

"Because wind energy is uncontrollable, it needs a certain amount of grid peak shaving capacity for its peak shaving."

"Once the available peak shaving capacity of the grid is insufficient, then the wind farm will have to limit the output."

"The larger the wind power capacity, the more severe this situation will be, and the more we need our energy storage business to play a role."

"We can build energy storage stations in various wind farms, store some or all of the wind power at the right time, and then send it to the grid at the right time."

"In this way, various problems of wind power can be solved to the greatest extent."

While looking at the PPT and listening to Lin Cheng's explanation, Cao Yang knew it in his heart.

This energy storage business has a head.

"In the future, the continuous increase of grid-connected wind power capacity, the contradiction between the policy of unconditional full purchase of wind power and the peak regulation and safe and stable operation of the power grid will gradually become prominent."

"This is indeed a good opportunity for us to grow our energy storage business."

"However, the energy storage business is basically not needed in Lingnan Province, can we consider building some battery factories elsewhere at that time?"

Cao Yang did not plan to put all the factories of Nanshan Battery in Yangcheng.

Especially in the future, Nanshan battery needs to supply to many OEMs, and the transportation cost of battery packs will be a sensitive topic.

Therefore, it is necessary to build multiple battery factories across the country.

Taking advantage of the development opportunity of the energy storage business, the factory layout of Nanshan Battery in time is also a good opportunity.

"There is a real need to think about that."

"We have an industrial layout in Chang'an City, and Nanshan Battery's factory in the northwest can be considered to be located in Chang'an City."

"Then in East China, we can also consider building a battery factory in a city near the magic capital."

"As for North China, it is possible to consider building a battery factory on the outskirts of the imperial capital, and there are three factories in a short period of time, which should be enough for the development needs of the next few years."

"If further development is needed at that time, we will consider it."

Nanshan Battery's plan to go out has naturally been considered by Lin Cheng for a long time.

So when Cao Yang mentioned this topic today, he quickly gave a proposal.

"Actually, I'm thinking, since we're going to do energy storage business, do we have to make a demonstration ourselves?"

"We do wind power bearings, and wind power blades are also ready to be made, so it makes sense to purchase a few wind power equipment that use our own parts, right?"

"These equipment with our bearings and blades installed, if we underwrite, then whether it is Modu Electric or other equipment manufacturers, it is estimated that there will be no doubt about the use of our products."

"And these wind power equipment can be placed on the edge of the Dongjiang River in the east of Yangcheng, and combined with our chip equipment industrial park, it can also form a unique landscape."

"When the time comes, we will build an energy storage station next to the chip equipment industrial park, and the electricity generated by the wind power equipment next to it will be stored in the energy storage station."

"This can not only solve the problem of unstable wind power, but also solve the problem of electricity consumption in the park."

"At that time, this solution can become a demonstration point, so that more customers can feel the benefits of energy storage stations in person."

As soon as Cao Yang mentioned this, Lin Cheng's enthusiasm immediately came up.

The concept of energy storage station has just been proposed, and now you can consider starting to build it?

If we follow this rhythm, the production capacity reserved in advance in Nanshan Battery's factory can be fully utilized this year.

Even this year, it is necessary to recruit workers in advance, according to the rhythm of three shifts, and go to production without rest on weekends.

After all, the demand for batteries in energy storage stations is huge.

The scale of hundreds of megawatt hours at every turn is definitely a very huge demand for today's battery manufacturers.

After all, Nanshan Battery, which ranked first in the industry last year, has a one-year production capacity of only a little GWH.

Build a few energy storage stations, and all this production capacity will be consumed.

What's more, Nanshan Battery also has a business of storage batteries, power batteries, mobile phone batteries, etc.

"Mr. Cao, your proposal is too second."

"The construction of the energy storage station can play a very good demonstration effect, and it can directly drive a significant increase in the production capacity of Nanshan batteries in the future."

"And the energy storage station has also contributed to the promotion of wind power components."

"Even in the future, our energy storage stations may not be used in the field of wind power, in order to balance the normal peak and trough of electricity consumption, we can promote the power grid company to build energy storage stations."

"The potential for business in this area is very intimidating."

"We are the first to propose the concept of energy storage stations, and when the time comes, we can lead the construction of relevant industry standards, so that our enterprise standards will eventually become industry standards."

"This trick is simply killing multiple birds with one stone."

Lin Cheng's mood was very excited at this time.

He originally just came to report to Cao Yang about the energy storage station today, and he didn't have much other expectations.

Unexpectedly, the development direction of the energy storage station was not only recognized, but Cao Yang also gave the first energy storage station construction proposal so quickly.

Even in this process, the wind power bearing and wind turbine blade business of Nanshan Group has also been driven.

The benefits to Nanshan Group in the future are absolutely unimaginable.

"The standard thing is really that you can't wait, and the threshold of the energy storage station is not particularly high."

"As soon as we start building, other battery companies will soon realize that this thing is good."

"At that time, it is inevitable that some other battery manufacturers will also start to enter the energy storage business, and it is still difficult for us to monopolize this market."

Monopoly is certainly the most lucrative and comfortable.

Of course, for those who are monopolized, this is certainly not the case.

Although Cao Yang does not expect to monopolize the energy storage business, it must become the industry leader.

The business that Nanshan Group wants to do, either not to do it, or to do it best.

Cao Yang even set a standard for the heads of each business division, that is, the business of each business division, if it can't be the top 3 in the industry, then it needs to be considered.

This is also a measure taken by some large international enterprises.

"I will immediately arrange someone to go to the chip equipment industrial park for on-site confirmation, and strive to come up with the design plan of the energy storage station within a week."

"Then together with all parties to start preparing for construction, and strive to build the energy storage station within this year."

"At the same time, I think we can also communicate with Modu Electric and share our thoughts with them."

"I believe that with your new proposal, Mr. Cao, they will be able to produce it soon using my new equipment for bearings and blades."

"Even if some of the tests are not completely completed, the delivery and installation of the equipment can be carried out simultaneously."

When you are a supplier and an end customer, you can be very flexible in many operations.

If the wind power equipment is sold to other people, Modu Electric will definitely not dare to be so bold.

However, the buyer is Nanshan Group, and the core change point parts are also supplied by Nanshan Group, so Modu Electric has a lot less concerns.

Sure enough, after Nanshan Group fed back the new plan to Modu Electric, Fang Hongmei was also shocked.

"Mr. Fan, Nanshan Group is very bold in doing things."

"The key is that after listening to it, I can't find a reason to oppose it."

Fang Hongmei and Fan Huabo are discussing the use of wind power bearings and blades provided by Nanshan Group.

If you simply deliver a few prototypes, it is not very difficult for Nanshan Group or for Modu Electric.

Everyone also hopes that this project will be implemented as soon as possible, so that wind power equipment using domestic bearings and domestic blades can have mass production results.

In this way, they will be more confident to promote to customers in the future.

"The fact that Nanshan Group has been able to develop to its current scale in such a short period of time must be the success of someone's family."

"Mr. Cao is not only very bold in doing things, but also has a deep technical foundation, the key is that he has a very strong vision, and the proposed plan is very innovative."

"I don't think any equipment manufacturer will refuse this kind of program to promote its own bearings and blades."

As soon as Fan Huabo said this, Fang Hongmei immediately added: "Mr. Fan, don't say it, Nanshan Equipment really didn't just find us this time, it is said that Envision Energy will also provide Nanshan Group with a few wind power equipment according to a similar plan." ”

"It is likely that there will be some other equipment manufacturers who will take the initiative to find this kind of cooperation plan that will make a steady profit without losing money."

"This plan is so good that all parties can't find any reason to oppose it."

During this time, Fang Hongmei's impression of Nanshan Group also had a 180-degree change.

A lot of things are put on Nanshan Group, and it is true that they cannot be evaluated with common sense.

Otherwise, there is no way to get an accurate judgment.

"That's what makes people so good."

"Not only have various wind power equipment manufacturers benefited, but they have also successfully opened up the market for wind power bearings and blades."

"And they buy equipment directly, which can be regarded as an example for other customers."

"The most important thing is that I heard that they are going to buy these equipment and go back to cooperate with the construction of energy storage stations, and they want to store the electricity generated by the wind power equipment into the battery, and then discharge it as needed."

"This idea is already wonderful."

"And this is not their most powerful place, what I admire even more is that this energy storage station uses the most batteries, and Nanshan Battery, a subsidiary of Nanshan Group, is the largest battery manufacturer in China."

"In other words, their plan is to kill one stone and string together many industries at one time."

"This kind of plan is simply flawless, and no one can jump out."

"Minister Fang, when your purchasing department deals with Nanshan Group in the future, don't treat yourself too much as Party A, everyone communicate well, maybe we can continue to touch the light of others in the future."

Fan Huabo is in a very good mood right now.

Regardless of whether the bearings provided by Nanshan Group are reliable or not, Modu Battery is a winner.

For Modu Electric, as long as the wind power bearings of Nanshan Bearing are officially installed on the equipment, it can directly bring the most direct pressure to the original suppliers such as thyssenkrupp and SKF.

It is estimated that their price increase request will soon become an active price reduction.

If the bearings of Nanshan Group are very reliable, taking this opportunity, Modu Electric has become the first equipment manufacturer in China to use domestic wind power bearings, and the symbolism behind it is also very different.

Maybe for this reason, you can still be on the news channel of Huaxia TV, or win a few more awards at the end of the year.

Modu Electric didn't suffer anything, and got so many benefits, Fan Huabo's impression of Nanshan Group soared to 100 points.

"You can rest assured, Nanshan Group is the largest private enterprise in China, and it is a key enterprise of the Government Council, and they don't regard themselves as Party A, so I thank God."

Fang Hongmei's words are really not polite.

As long as the strength is strong enough, the positions of Party A and Party B can sometimes be swapped in minutes.
