Everything is a bit, Huawei makes electricity smarter

"What is the origin of the world?" On this planet where human civilization continues to progress, wise men of different eras have given answers.

Everything is “It from bit”, that is, the physical universe originated from information. John Archibald Wheeler, a famous American physicist and the name of black holes, It was proposed in Chapter 6 "Beyond Black Holes" of "At Home in Universe" completed in 1989, when the information revolution was gaining momentum.

John Archibald Wheeler emphasized the significance of observation. He and scientists led by Bohr believed that when the world is not observed, it is just a lot of "number smoke" (probability waves or possibility), time, space, matter, and energy are immersed in it, and people use "observation" to create the reality in their own eyes. Materialized nature and digital nature are increasingly integrated with information and communication technology, and atomic bitification is an important feature of the intelligent world.

In the field of electric power, as communication technology evolves from analog communication to digital communication, optical fiber communication, the Internet, wireless communication and satellite communication develop rapidly, and communication networks are moving towards large capacity, high bandwidth, wide coverage and large connections, and low power consumption. The evolution of the collaborative integrated communication network of "air, sky, earth and sea" with high latency, high reliability, heterogeneous integration and customizable capabilities. At the same time, electric power information technology continues to innovate, chips are developing towards ultra-large-scale integration and high performance, computing speed is changing from single-core capacity improvement to distributed computing, storage space is getting larger and larger, and networks continue to evolve towards cloud platforms, providing power systems with Continuous intelligent development has built a solid digital base.

Huawei is committed to promoting the digital transformation of the electric power industry and has proposed the vision of building a power digital world in which bits and watts are deeply integrated. It is precisely from the perspective of bits that we look at electricity. The video "Journey of Electricity" shows that bits give Watt the intelligent abilities of "perception", "prediction", "insight", "thinking", "learning" and "love", etc., and carries Huawei's core concept of making electricity smarter, through the creative expression of the journey. , reflecting Huawei’s capabilities in one-stop digital transformation solutions at source, network, load, and storage.

In a gust of wind, a ray of light

I was born

Bits give me wisdom

p>

A journey of infinite possibilities has begun

Through mountains, forests and valleys

I can sense and predict

No matter how dangerous the place is, I can go all the way Smooth road

I am willing to discern needs

If someone calls

I will rush there with millions of companions

immediately

Spread the news to thousands of households

Work together to turn uncertainty into certainty

I am good at thinking

Not only do I realize my potential at every step

It is even more important to identify risks lurking in disorderly changes in a timely manner

Avoid in advance and move forward steadily

I am passionate about dedication

The city is asleep

I am still full of energy

For those who are tired, come home late, and walk in the dark

Give a little light and a safety

I will also learn

Learn to turn ordinary life into joy

After a long journey, I finally understand

Love is always with you when you need it

Let every choice have a response

Love requires timely communication

Respond to everyone behind you who supports you

Regardless of the other party Where and when

My journey is far from over

Wisdom gives me infinite possibilities for the future

The power system is the most complex Artificial systems. Taking the field of electric power information and communication as an example, "control" has expanded from local to global, "control" has extended from the backbone to the periphery, and information "collection" has exploded: electricity meters interact with the power grid, massive non-metering information; demand-side response, user equality Interaction; the collection point is moved downward, and the energy terminal is measured with the device; the collection frequency and real-time performance are improved (15ms), "new energy" (solar energy, wind energy, distributed energy storage), "new business" (EV charging piles, smart parks , smart home) are connected on a large scale, and new demands (status monitoring, real-time perception, closed-loop control) are emerging one after another.

China’s primary and secondary electric power systems have experienced a process from weak to strong, from simple to complex, and today we have the world’s largest power grid with world-class power supply reliability and serving a global population of 18 . With the proposal of dual-carbon and new power system strategies, power people have new goals to continue to overcome difficulties. The new power system requires a significant improvement in the ability of information communication to support power grid services. It needs to be high-speed, real-time, and reliable to achieve comprehensive perception and full online. It requires information communication capacity and its breadth, openness, interactivity, intelligence, and availability. Credibility raises new demands.

Dawkins, the famous British evolutionary biologist, used "The Blind Clockmaker" to refute the "creator theory" ("blindness" is a metaphor for evolution without prophetic direction and random mutations). "Clocks" are exquisitely accurate and ingenious. "Creatorists" believe that the Creator controls the movement of the world like a clockmaker. In fact, human evolution is more like a blind watchmaker, dismantling complex systems into the tiniest parts. There is no pre-drawn blueprint, but it is through the superposition of continuous error correction processes that we have reached today's complexity. degree, thereby proving the correctness of the "evolution theory".

The development of electric power digitization and intelligence is also based on the "evolution theory". For example, G.652 optical fiber restricts the development of the system towards high speed, and G.653 optical fiber restricts the development of multi-channel multiplexing. G.654 optical fiber and G.655 optical fiber have greater advantages in terms of loss and long-distance transmission. With the emergence of data floods, large-capacity optical fiber communications play a huge role. After comparing SDH, OTN, PTN and other technologies, and taking into account bandwidth granularity, security and other factors, it is determined that SDH and OTN technologies are the most ideal choices for power transmission networks and will be used in power transmission networks. Electric power backbone networks are widely used. Huawei's optical transmission products have been deployed in more than 40,000 units in China's ultra-high voltage, inter-provincial backbone, provincial backbone, and prefecture-municipal power transmission and transformation communication networks. They have large bandwidth, ultra-long distance, lightning protection, and 2M optical relay protection. , ASON, TSDN and other innovative features rank first among similar products in the world.

In terms of system complexity and data processing capabilities, from single chip microcomputer, numerical control, DCS, SCADA, EMS, stability control, to electrical information collection; processor frequency started from KHz and has developed to above GHz; GPU , chips, quantum chips, with the improvement of computing and storage capabilities, analysis algorithms are also constantly evolving, such as perceptrons, BP neuron networks, expert systems, support vector machines, deep learning, deep reinforcement learning, adversarial learning, etc., fully It shows that intelligence is not formed in a day.

In the future, emerging digital technologies will deeply penetrate and influence the construction of new power systems, promote the complementary application of multi-energy and the coordinated development of source, grid, load and storage, and help achieve clean, low-carbon, safe, reliable, smart, flexible, cost-effective, etc. Target. With the in-depth development of ICT technologies such as cloud computing, big data, Internet of Things, mobile communications, artificial intelligence, and blockchain, digitalization has become a key production factor in this era and the basic competitiveness of enterprises. The application of digital technology will be written As more and more informatization elements enter the DNA of enterprises, those enterprises that are better at using digital technology are more likely to be "naturally selected", and on the contrary, they will be gradually eliminated.

Human beings cannot live without dreams, and the Metaverse is the "reality" that many people dream of.

In the power industry, as digital twins and virtual reality technologies become more mature, and various information technologies and equipment improve, the application of virtual reality technology in power systems will become more and more widespread. For example, traditional power monitoring systems (such as data acquisition and monitoring control systems) are generally built based on two-dimensional configuration systems. Their operation flow charts are mainly two-dimensional primary wiring diagrams, which use two-dimensional graphical symbols to display all users in the substation. Electrical equipment and circuits provide instantaneous power (three-phase current, three voltages, active power, reactive power, active energy, reactive energy, power factor, frequency, etc.) for dispatching and centralized control centers, and each circuit breaker real-time information such as operating status and fault conditions of each circuit. In the future, all information will be presented in three-dimensional form, and you can be immersed in a substation thousands of miles away, and view various real-time data at any time, conduct research, make judgments, and perform maintenance.

Behind such a fascinating virtual world of the "Metaverse", a real network is needed. Huawei is building a smart world where everything is connected from four aspects: "ubiquitous connectivity", "omnipresent intelligence", "personalized experience" and "digital platform".

Taking the power industry as an example, in terms of ubiquitous connectivity: Huawei helps the State Grid build an ultra-high-speed, large-capacity 100GOTN power communication network digital infrastructure to fully serve the digital transformation of the State Grid and the construction of new power systems. .

In terms of all-encompassing intelligence: Huawei and its partners *** jointly create a "four-no" ecological camera power transmission intelligent inspection solution. Its self-organizing network and other features are used in China Southern Power Grid to reduce the multi-span problem in Zhongshan. It provides an overall solution to the risk of external breach in the scenario and solves the problem of inspection video backhaul in the blind area of ??Diqing public network coverage, becoming a model point for intelligent inspection of electric power transmission in the world.

In the field of smart dispatch, Huawei has created a distributed energy dispatch group management and group control solution based on the core technology of "5G edge computing", helping Shandong Power Grid take the lead in realizing "10kV new energy stations, large-load users, local power plants and small thermal power plants". "5G direct procurement and direct control" and "multi-service integrated intelligent APP" under business scenarios have created the country's first commercial pilot of smart dispatch with new power system characteristics.

In terms of personalized experience: Huawei and State Grid Xi'an Power Supply Company jointly created an emergency command plan to ensure power supply. Through Huawei's ISDP digital operating platform, 300 points of concurrent smart wearable video are accessed to achieve panoramic real-time monitoring of the site. , dynamically controllable resources, intelligent emergency research and judgment, and on-site penetrating command to help ensure smart power supply during the "14th National Games".

In terms of digital platforms: Huawei worked with partners to release a "smart power plant" solution, creating an innovative integration solution of "one network", "one platform" and "multi-dimensional intelligent analysis" at Ningzhou Power Plant, and continues to provide Power plant companies across the country have built a digital platform base for smart power plants.

Everything is a bit. Bits are the unit for measuring information. Information is uncertainty, degree of difficulty, and entropy. Communication is to eliminate uncertainty. The history of human progress and civilization is, to a large extent, The history of improving the efficiency of information dissemination. Huawei's inherent advantage is connection and computing. If the universe is a huge information processor, Huawei is using ubiquitous connections to offset real uncertainties with virtual certainty, and making everything possible through omnipresent intelligence. It is the algorithm running in the universe. On the digital base of the future smart world, Huawei's shining imprint must be engraved.
