On September 27, the China Comprehensive Dynamic Service Industry Innovation and Development Alliance jointly organized by the China Electric Power Sales and Comprehensive Dynamic Service Branch, jointly organized by the China Electric Power Sales and Comprehensive Dynamic Service Branch, was grandly held at the Beijing Fishing Platform National Restaurant. At the National Day, in the “Energy Achievement and Comprehensive Dynamic Service” segmentation, Pei Zheyi, a senior engineer at the national power distribution control center, delivered a purpose speech, and distributed it to friends on the situation of new power and electrochemical energy acquisition, future analysis, policy analysis and installation principles.
The following is a lecture record:
You are the leader and expert teacher to give a war book! Pinay escort
First thank you for the invitation from the conference, and I will give it to my friends with the master to develop needs in the battery. Some of the results of our colleagues’ many years of work, and some only represent personal views. We told the master in three aspects that new forces and electrochemical capabilities are integrated with the online situation, future analysis, policy analysis and installation principles of the installation.
Tomorrow we will analyze it. In the future, we will play the main color, especially the master of setting up the equipment, so we will simply share it with friends with the master.
1. New power and Internet-based situations
Why do you say new power? It can be said that the power system now includes flexibility and future energy storage, so let’s briefly put it, as of the end of previous years, new power installations were 410 million kilowatts, an increase of 16% year-on-year. It is the country with the largest network capacity in the world. The total new power installations account for 21%, and the new power installations were 56.1 million kilowatts, accounting for more than half of the total new power installation capacity. This number is very large, and has exceeded the burden in some areas.
New dynamics are developing into new stages, which is our personal view. With the development of new power, new power installations have become the second largest power supply in my country. In addition to firepower, it has become the first power supply in some regions. For example, new power installations in northern Hebei, Gansu and Qinghai have exceeded 100% of the load, and nearly 20 provinces have exceeded the second largest power supply. Some power transmission transmittance exceeds 40%, which has an increasingly prominent impact on the safety and stability of the power network.
I want to explain the transmission rate. This is the appropriate time data. The non-network investment rate in the Internet exceeds 40%.
Since previous years, the national Internet area has been more than 95%, which has basically reached the world’s advanced level. In the past few years, it can be said that it is less than 90%, and this year it will also exceed 95%. The problem of the problem has been solved.
If the past is a technical problem, enter the new era of the Internet, 50% of the Internet will beAfter the asynchronous network comes in, how can the Internet Ping An solve the problem?
A brief introduction, and briefly talk about energy storage at the end. National Internet has invested 576,000 kilowatts of energy storage. The power storage capacity on the Internet has developed rapidly, with the machine capacity reaching 330,000 kilowatts, becoming the main driving force for energy storage development. The development of Internet storage can be accelerated as much as possible after it is available, but the development rate is still very fast.
The master looked at this picture and the user side was only 106,000 kilowatts, but the amount was very large. The ability to achieve peak-to-valley arbitrage in the eastern part of China is to develop important application energy, and the capacity is large in time. However, it can be seen through the under-construction that the Internet side and the power side, in recent years, the policy foundation has been building on the Internet side, and the red-based trend has reflected from the past to the current development of energy.
I just said that it can be used in various rings, including male actors of similar power bit ages. The other three are middle-aged men. On the side, Qinghai and Xinjiang were important to reduce the abandonment of wind, and some of the more important power stations were built on the Internet, Henan, Jiangsu and Guangning. They were all on the Internet, and there were also Guangdong, Shanxi, Hebei, and others including micro-networks.
Electronics and chemical energy is currently a form of business, and it is now a form of exploration. It is relatively refreshing on the side of the user, which means peak-to-valley arbitrage, and the integration of light increases efficiency. With the price adjustment in these two years, the arbitrage gap on the user side is also decreasing. The power supply side is heavySugar babyIf the pyroelectric and new power stations participate in the service, they will increase the power generation along the way with the new power stations. The important part of the Internet is the method of renting. This method is worth thinking about after the transfer price was not allowed in previous years. There are also independent third parties, and they just talked about Gansu and also the big ones. Now they want to use capacity and electricity prices, but now they have not come out.
2. Analysis of application scenarios in the future
I have to talk about new dynamics again. By 2035, the capacity of new power installations exceeds that of coal and electricity will become the first power supply, and the largest number of new power installations is also saying that the development of new power development is also accelerating. By 2035, the major trend and new power installations will be 1.35 billion yuan./philippines-sugar.net/”>Manila escortwatts, the proportion has increased by 37%, and the power generation capacity is more than 24,000 yuan, which will also be adjusted according to the planning adjustment. Below are two very classic scissors, with coal and electricity gradually declining, and new forces gradually increasing.
Tomorrow morning, it will be proposed that carbon integration will be realized by 2025, and will develop new forces againSugarSugarSugarSugar Baby‘s new requests are put forward. Another thing is that my country’s cleaning power resources and negative loads are in reverse distribution, 80% concentrated in the west, and 70% negative loads are distributed flat in the middle and eastern part. There is also a new dynamic development that adds the difficulty of network regulation. Compared with many people, many people have improved network activity, elastic network, etc. The major thing to talk about is the flexibility of network. In the past, networks usually used electricity to follow negative loads. Now, electricity generation is also a random one. href=”https://philippines-sugar.net/”>Manila escort is also random, just that both sides are unwilling to accept the balance, you How does Escortequilibrium it? This adds the need to fluctuate, and the load changes of other networks are very regular.
The bottom is Southeast Electric Network. The red line is based on the loads of the previous month, but there is no rule in the wind power generation for a month. The maximum number of Southeast Electric Network is 30 million kilowatts. manila, with a minimum of more than 2 million kilowatts, less than 10%, this wave is very large. On the right, it is also the “dragon curve” of Shandong’s negative load. It has two locations from 3:00 to 4:00 in the morning, and 12:00 in the afternoon, and 12:00 in the middle of the night. It is because of the participation of a large number of photovoltaics. The peak is very difficult now. The fire is adjusted twice, and the demand is adjusted at noon and the night after night, and the rise is still steeper.
This block also has 20 The students and professors conducted fierce discussions. Among them, the most famous one reached 7000 million and 650 million kilowatts in 35 years, and the largest wave network should adjust the daily power wave volatility of 500 million. What is the concept of 500 million? Now there is only less than 3 billion in Huadong. How does this wave volatility correspond to the future of the problem.
There is also a new power to participate in the ability to resist interference in the future. This is the result of the simulation, and the degree of disagreement is handledManila escortThe Internet is stable, taking a certain western network as an example, the 3.5 million kilowatts of work is lost at a load of 68 million kilowatts.If the risk-free online is increased by 0.65Hz, the frequency will drop by 12 million kilowatts and the frequency will drop by 0.95Hz, which will increase by 0.3Hz compared to the time when the risk is not increased. In the future, the system frequency adjustment can further improve with the expansion of the fan scale and the solar energy scale. Nowadays, the maximum number of wind turbines is 30,000 to 40,000.
What are the application scenarios of power system? Make a simple summary: 1. Improve the Internet-related characteristics of new power, reduce TC:
