/ August 10, 2022 Guangzhou -- Energy conservation and emission reduction have become a global consensus. As China officially announced the timetable to achieve the goal of "double carbon", local governments and industrial authorities at all levels have introduced relevant regulatory policies, and countless enterprises have also felt unprecedented pressure to "live green".
The International Energy Agency predicts that the share of global electricity generation from fossil sources will fall from 60 per cent in 2018 to 20 per cent by 2050, with renewables expected to account for more than 75 per cent. "Continuously increasing the proportion of non-fossil energy in primary energy consumption" is not only a global consensus, but also an important path for China to achieve the goal of "dual carbon". The main form of non-fossil energy consumption is clean electricity converted from non-fossil energy. It is foreseeable that clean electricity will play an important role in China's low-carbon transition in the future.
Ren Jing, senior vice president of Schneider Electric and head of low-voltage business of energy management in China, who has been deeply engaged in the energy industry for nearly 20 years, believes that clean power is the core of energy decarbonization, and a new power system that can adapt to new energy as the main body needs to be broken.
Ren Jing, Senior Vice President of Schneider Electric and head of energy Management low-voltage business in ChinaRelated to it, on March 15, 2021, the ninth meeting of the Central Financial and Economic Commission put forward the concept of "new power system" for the first time. Over the past year, "Building a new power system" has increasingly become the common vision and guide to action of all social stakeholders.
Traditional power system transformation encountered a dilemma < p>
Currently, based on the "dual carbon" goal and the consensus of building a "new power system", enterprises at all levels across the country have been actively deployed to improve energy efficiency and energy management level. In Ren Jing's opinion, the essence of building a "new power system" is to promote the transformation of energy structure and the large-scale access and efficient utilization of new energy in various industries and scenes.
However, it is not easy to shift the energy structure and accelerate the replacement of new energy sources. Due to the general characteristics of volatility and randomness of new energy, its large-scale development and high proportion of grid connection have always been a thorny problem for the traditional "source-on-load" operation mode. From the power supply side, after the distributed energy, represented by photovoltaic and wind power, is connected, the prediction accuracy of electricity load decreases significantly, and the inherent volatility and randomness of new energy greatly increase the stability risk of power grid. On the power demand side, with the deepening of urban development and electrification degree, the peak-valley difference of power grid load increases year by year. The original relatively stable law of power demand is being broken, and its impact on the stability of power system will inevitably become the new normal.
Not only to vigorously promote the energy structure to the new generation, but also to cross the road block facing the new system, how on earth to crack this "dilemma" realistic proposition? Ren Jing believes that scientific construction of a clean, low-carbon, safe and efficient new power system with new energy as the main body should be taken as the core step to solve the problem, among which, digitalization is the key to the construction of a new power system. < / p > < p > < b > for the new power system equipped with digital engine < / b > < / p > < p > if "+ digital automation" is the "4.0" industrial characteristic, then "electrification + digital" is one characteristic of "power 4.0". "Digitalization is an important trend for the power industry." According to the understanding of Wu Ming, technical research and development director of State Grid Shanghai Energy Internet Research Institute, digital technologies represented by digital twin and visualization can greatly improve the operation quality and management level of distribution network, and the future electricity trading link also needs digital technologies to support.
Ren Jing believes that the large-scale integration of digitalization and electrification will lead to a new world of electricity. The new power system with new energy as the main body needs a lot of information collection and operation analysis to ensure the safety, stability and reliable power supply of the grid. Once artificial intelligence, cloud computing, 5G and other digital technologies can be applied in all aspects of power generation, transmission, transformation, distribution, use, storage and so on, it is bound to accelerate the digital transformation of the power system.
As early as 2021, Schneider Electric, with its profound insight into the market, cutting-edge expertise, innovative technology and agile development ability, put forward the concept of "green energy management" and came up with a complete set of solutions. "Electricity is related to carbon emissions, and carbon emissions are related to energy consumption. Only when these factors are digitized can they be scientifically managed. Digital is Schneider Electric's philosophy and thinking mode, and it has become a very key core competitiveness of Schneider Electric." Ren Jing has a clear insight into the convergence trends and market opportunities of electrification and digitalization.First, digital technology helps ensure electric power security. The process of ensuring power grid security is a process of dynamically discovering defects and blind spots. Without advanced digital intellectualization technology and specific digital parameters, it is impossible to come up with an effective improvement plan. Moreover, the digital upgrade of traditional power equipment should adopt "digital native design" equipment in the whole life cycle and project process, so as to better respond to the needs of various application scenarios in the digital environment.
It is understood that in the "toolbox" of Schneider Electric, intelligent patrol technology of transmission lines, intelligent substation technology, intelligent distribution power station, micro grid, intelligent gateway can help enterprises realize intelligent operation and maintenance, and intelligent asset operation and maintenance technology can improve the power grid's ability to prevent security risks.
Second, digital technology improves the flexibility and reliability of energy use. The traditional power system has the characteristic of "source moves with load" and is highly dependent on power dispatching. However, under the trend of deep electrification, the randomness and interactivity of power supply and demand are greatly improved, and each link of charge and storage in the source network is coupled and deeply interactive.
Third, digital technology dynamically optimizes energy efficiency management level. Digital dynamic technology can make invisible energy use and performance in each link transparent and visible, effectively detect system risks and redundancies, so as to optimize the architecture to improve energy efficiency, and ultimately help enterprises achieve business goals and double carbon goals win-win.
The Schneider Electric Institute of Business Value recently released the "Green Path - New Power system Industry Insight" prospectively pointed out: "A micro-power ecosystem with multiple forms of distributed energy, storage infrastructure, flexible intelligent distribution networks and measurable controllable loads" will prevail.
The establishment of the "micro-power ecosystem" requires the combination of powerful digital terminal equipment, green energy management system and new power electronics technology to enable. An industry insider introduced in the interview, in the "double carbon" and "new power system" double concept boost, social capital is urgently looking for both advantages of the industry "unicorn", many enterprises at home and abroad are in the direction of "electrification + digital" product generation and technology innovation. But in fact, whether do "source network load storage" or do "light storage straight soft", almost no one can do all the links do fine.
Ren Jing also holds a similar view. In her opinion, any enterprise to understand the "electrification + digitalization" this "chain", in addition to have a complete product matrix, also must have strong technological innovation. Schneider Electric's unique trinity of "critical innovation" is what has made its products and services ubiquitous and consistently leading the industry over the past two to three decades.
One of the magic weapons is the strength of "innovative products" to respond to market demand. Since its entry into China 35 years ago, Schneider Electric has established a wide range of product sales system in the country, and built a digital R & D innovation system with full coverage of hardware and software. In 2018, it started to shift to the "multi-hub" mode in the Chinese market. By establishing a Chinese innovation center integrating technology, research and development, and sales support in China, it is more suited to the needs of local users. "Multi-center" mode not only accumulates diverse application scenarios and experience for Schneider Electric, but also trains the company's own response speed in the rapidly changing Chinese market.
Jing Ren introduced that it is based on the high attention to research and development and continuous investment, Schneider Electric can continue to provide the market with green, intelligent, digital innovative products, through the material, design, structure and other levels of innovation, for customers to bring safe, reliable, green, environmental protection user experience. In 2021, Schneider Electric launched TeSys Giga Series of motor control and protection products, which can not only alert customers to the aging condition of equipment, but also replace only the contact unit from the traditional complete machine, greatly reducing customers' carbon footprint at the equipment level with minimal parts replacement. And the use of "fully modular, fully digital, fully intelligent" design, to help users to shorten the machine time to market by 50%, improve the efficiency of the selection design stage by 50%, and reduce the downtime probability of more than 50%, to bring customers a minimalist experience.The second magic weapon is to enable the digitalization of the industry by "software end to end". The essence of digitalization is process management. "End-to-end software" should not be just a simple SaaS software. It is based on long-term observation and deep understanding of the industry, the scenario, and the requirements. According to Ren Jing, Schneider Electric advocates the "agile development" and "joint development", are built on the open, embrace customers, with the change of demand and change based on, and is iterative, low quantity and variety of development, "who can do better than the industry to understand the industry, who can talk about the ability to double carbon and digital transformation of the industry.
In the field of energy management, Schneider Electric has developed its own intelligent power distribution system software, together with IGE+XAO in the field of electrical design, ETAP in the field of electric facility simulation analysis, RIB in the field of building 6D BIM, etc., to provide various industries with digital integrated energy management solutions, achieving end-to-end energy management.
The third magic weapon is the ability of "integration of source, network, charge and storage" to help enterprises accelerate the realization of carbon neutrality. With the continuous development of new power systems and digital energy ecosystems, more and more micro-networks, energy producers and consumers, and the cross-integration of source network, load and storage require more intelligent control. Ren Jing believes that improving energy efficiency and management level is the propeller to achieve the goal of "double carbon", and clean electrification and digitalization are the two key driving forces of this propeller. Enterprises on both sides of supply and demand need to carry out more active deployment in the aspects of digital innovation application, improving energy efficiency and management level.
For example, Schneider Electric has created a distributed energy system with microgrid as the core for Zhejiang Xinmei Electric, which realizes the prediction and optimization control of rooftop photovoltaic, energy storage and flexible load with digital technology, and realizes the "multi-energy complementary" function centered on electricity, which is both economic and green. Through this project, Xinmei Electric will achieve an annual increase of 146% in new energy power generation in 2020, increase the annual penetration rate of new energy to 70%, and save more than 30% of the total annual electricity cost. It is the first enterprise in Zhejiang Province to obtain the "carbon neutral" certificate, and lays a foundation for realizing "green Industrial park" and "zero carbon industrial park" in the future.
Facing the increasingly refined and diversified demand for carbon reduction, it is difficult to respond to the market quickly with the ability of a single enterprise. This requires the joint innovation mechanism to strengthen the "joint co-creation" of the ecosystem. To this end, in 2021, Schneider Electric, together with Ningde Times, Star Charging, Tsinghua Sichuan Energy Internet Research Institute, Rocky Mountain Research Institute and other institutions, jointly launched the "Green Energy Management winning Plan" for scientific and technological innovation enterprises, and carried out "joint innovation" with Mingyang Group, Ningde Times and other enterprises, through close cooperation with ecological partners, Jointly promote the implementation of innovative technologies.
It is worth noting that the cooperation with Mingyang Group is an important practice of agile development of Schneider Electric. Ren Jing introduced that offshore wind power is a green energy with great potential. Schneider Electric signed a memorandum of cooperation with Mingyang Group in March 2021, promising to jointly conduct product research and development, jointly develop industry standards and carry out in-depth cooperation in new business models. In collaboration with the floating offshore wind project last year, Schneider Electric launched MTS-T6 special air circuit breakers for offshore wind within six months. This circuit breaker not only has a full series of 1140V/66kA high breaking capacity, but also adopts special material process anticorrosions. It has successfully passed the special test certification of various stringent environment of floating offshore wind power, and its performance is superior to that of the industry. The rapid introduction of this product has also successfully ensured the continuous healthy operation of offshore wind power equipment.
< /p>This year, Schneider Electric launched a new "Sustainable Development Partner Program", focusing on providing partners with simple and convenient product solutions, an open and collaborative supporting ecosystem, and sharing rich digital knowledge and practical skills.
