Without colorful sea water, Pattaya Beach on the outskirts of Bangkok, Thailand, may not be so famous in the world.
If there were no Indian literary film “the color of Pattaya” starring Amir Khan, the outside world would not even know that such a common place name could be associated with the bloody revolution.
Without the word “ubiquitous”, the power Internet of things may be just an ordinary industrial concept, let alone a sense of science and technology.
In early March 2019, the State Grid officially launched the outline and action plan for the construction of ubiquitous power Internet of things. After that, the A-share power sector, including Taihao technology, rose in response to the limit.
The outside world knows that this common term will be so extraordinary.
The essence of “ubiquitous”
In the past decade, the ranking of the world’s top 500 of the State Grid has changed from 15 to No. 2, and the revenue has doubled, but the technological climb of Lin Yue in this decade is just a wave in five years.
In 2009, the Obama administration launched the concept of smart grid, and the State Grid officially released the development strategy of “strong smart grid” at the “2009 International Conference on UHV transmission technology” held in Beijing in May that year.
In 2014, with the development of distributed energy and energy transformation, Europe and the United States launched the concept of energy Internet, and the State Grid kept pace with the times again. At the 2014 meeting of the society of electrical and electronic engineers held in Washington, the United States, it was proposed to build a “global energy Internet” to connect large wind farms and photovoltaic power plants with “one pole and one road” (Arctic and equator) to adapt to various centralized Distributed generation, promote the wide application of smart grid in the world, strengthen energy and power technology innovation, and finally realize intercontinental, intercontinental and global interconnection.
Times are changing and innovation remains the same. Although the prefix of two words is only the finishing touch each time, the sense of transcendence and the sense of earth atmosphere always penetrate the back of the paper.
“Ubiquitous” is really the finishing touch for the power Internet of things. It can easily separate the two times of “Internet” and “Internet of things” – the essence of the Internet age is informatization, and the essence of the Internet of things is digitization.
The biggest similarity between the two is that they both need capital, technology and scenarios to promote; The biggest difference is that informatization seems to be more perceptual to serve people. The basis of digitization is industry, which can be transmitted to people through more rational service equipment.
The next three decades will be a transformation from the connection between “people” to the comprehensive connection between “people and things and people”. The “ubiquitous” reveals the essence of this transformation: it is no longer influence and penetration, but encirclement and melting.
From the perspective of English, the most appropriate translation of “ubiquitous” should be ubiquitous in Latin, which means “God is everywhere”.
On the surface, this word only declares the basic characteristics of being omnipresent, omnipotent and omnipotent all the time, so that anyone and anything can be connected at any time and anywhere.
But in fact, the core of “ubiquitous” is:
Since electricity will reach all people and things in time domain and airspace without restriction, the resulting network will easily upgrade all analog signals to digital signals, so as to quantify and calculate everything until all products and solutions are integrated into clear and controllable services, and people just live in the scene constructed by things, The scene itself is ubiquitous in the power Internet of things.
The plan of this strategy is large, and the scientific expression is that the strong smart grid carrying power flow and the ubiquitous power Internet of things carrying data flow jointly constitute the “three in one” energy Internet of energy flow, business flow and data flow.
Generally speaking, this is tantamount to eating the Internet with the Internet of things, swallowing physics with mathematics and killing operations with scenes.
“Energy Internet = strong smart grid + ubiquitous power Internet of things”. Looking at this simple and effective formula from the above interpretation, we will find that the state grid does not simply put the power grid across the world and focus on the user side, but carefully shows the evolution order of “three types and two networks”.
This order is: start from the essence of power, fully share on the basis of being the hub and platform, and then move from sharing to the platform in the larger collection of Internet of things and ubiquitous network, until it becomes the hub of all in and all out.
The five scenarios, three types and two networks are all for one transformation: expanding the practical requirements of business data to the future ubiquitous of data business, which is the essence of ubiquitous power Internet of things.
SG eiot (electric Internet of things): combine the five businesses of power transmission, transformation, distribution, power consumption and operation with communication, computing and control technologies, integrate the five systems of terminal, network, platform, operation and maintenance and security into the network, cloud, layer, edge and end, and turn power, data and services into an inexhaustible infrastructure flow.
Can an elephant dance?
When it comes to a great dream, while the blood is boiling, we can’t help asking about the implementation path. It seems that the greater the dream, the harder it is to land.
However, it has to be said that after seeing the great changes of high-speed rail and the Internet in China in the past decade, China has the courage and strength to dare to fight for a big dream.
Moreover, the biggest difference this time is that we no longer follow the rules and regulations when foreign countries have concepts and innovations, but independently relax such a concept after integrating more elements and extensions.
Theoretical support and planning steps may not have to worry.
On the one hand, the essence of the mobilization of the State Grid is not only quick to put forward the construction outline and action plan, but also the decomposition steps and target directions of all provinces and departments have been clearly defined in the shortest time.
On the other hand, there are many stones that can be touched abroad in terms of technical support and innovation attempts.
For example, among the earliest energy Internet demonstration projects implemented in Germany, there is a MoMA project implemented in Mannheim, the most digital city, which uses the concept of cell grid to make power supply and exchange ubiquitous.
However, digitization sounds simple, but it costs a lot: Mannheim’s streets have no name and are replaced by signs such as Q3 and L4.
Manheim has many satellite cities, and the energy supply is largely from distributed energy. On the basis of the concept of microgrid, MoMA proposed that cell networks are like human cells forming tissues.
Organizations and organs have a hierarchical structure, and the power grid is also composed of multiple cell cluster networks, which are composed of multiple cell networks, so as to realize hierarchical system operation, cell system control and nearby power consumption.
671 families participating in MoMA also installed energy routers and control equipment called “energy housekeeper”, which automatically shut down and turn on household appliances according to user settings and electricity prices.
The results of the project show that users can save up to 11% of electricity charges.
The biggest highlight of MoMA is its cell grid. Each family is an object cell. Every 200 object cells are connected to the distribution network cells, and 300 distribution network cells are connected to the system cells.
Each cell in the cell grid can optimize itself and try to balance and adjust. Cells communicate with superior cells through PLC, and superior cells identify subordinate cells through IP.
At the level of object cell and distribution network cell, only through the market regulator and power grid regulator of automation and software, the system cell has the role of dispatching and controlling the power grid and a complete power trading mechanism.
In this way, the system cells only care about the interface volume of the distribution network cells, rather than the photovoltaic panels or household appliances in each household user.
Such a “system of systems” is to cope with the access of more and more distributed energy. The number of equipment is so large that it will be too complex to use traditional regulation methods. Its essence is a micro ubiquitous simulation of super large power grid,
The power quality, voltage, frequency and phase angle of each cell grid should be guaranteed within a certain range.
Therefore, the architecture of cellular power grid has higher requirements for power production than traditional power grid.
The conclusion of this project verification is that for a large system, the real limit is not the number of equipment and data capacity, but methods and strategies, although the former will be more important for investment and operation.
But the real challenge facing this energy Internet plan is not the Internet of things and power itself, but people.
Due to the consideration of security and thinking limitations, few people can push the construction plan of animal networking purely with digital thinking ability.
Take winnode, another energy Internet demonstration project in Germany, as an example. Through the windnode project, various partners from the energy economy and information and communication industries will interact with industrial, enterprise and even private energy users.
The East German power grid 50Hz company will undertake the coordination work, and the coordination partners include distribution network operation companies stromnetz Berlin and wemag; Technology companies such as Siemens, Bosch Si and T-system; New energy companies belectric, enertrag and Parabel; Urban public service company (stadtwerk) and housing economy company; Important industrial partners in energy transformation, such as automobiles, infraleuna and global foundries; Retail supermarkets lidl and kaufland (Schwarz Gruppe); Innovative enterprises such as grundgruen and ibar; And the initiative volunteer organization “meine Energie Fuer meine Stadt”.
In addition, famous universities and scientific research institutions will provide scientific research support and close cross-border exchanges, including tauron dystrybucja S.A., a Polish distribution network operation company.
Even if such a huge network is not a problem in terms of time, financial, material and human resources, only those who have done innovation will understand that what really makes innovation collapse is not the conservative who is complacent, nor the opponents who show their teeth and claws, but all kinds of colleagues and subordinates in the innovation camp who have their own opinions and different horizons.
For one thing, even if the “top” wants to see it clearly, it often becomes sticky and doesn’t end up at the “bottom”, which makes people feel helpless.
The advent of “ubiquitous power Internet of things” in early 2019 may prove this. When the leadership is making steady progress, practitioners at the provincial and municipal levels are blankly asking “what is this in the end”.
But in addition to elephants like the State Grid, who else can lead the crowd to turn around and break the game.
A fact is that the development of the energy Internet over the past five years shows that private enterprises and external capital have proved unable to pry the whole situation and can only rely on elephant dancing to maintain the situation.
Therefore, elephant’s innovation should enjoy warm applause and return to the most profound rationality for this digital transformation.
I hope rationality can also repay everyone involved in this change, just like the colorful waters of Pattaya.
