/ Asahi/August 30, 2022 Guangzhou - This year, global climate change and international crises have heated up the "energy topic" again, and pushed the development of new energy around the world into a fast track. In China, based on the "two-carbon" commitment, the new power system with new energy as the main body is undergoing accelerated reform, and the installed and generated power of new energy represented by wind power and photovoltaic power will gradually increase. It is expected that by 2030, the installed capacity of wind power, solar power and other new energy sources will surpass coal power and become the largest power source in China. By 2060, new energy generation is expected to account for more than 50% of the total power generation. The rapid expansion of new energy brings both opportunities and challenges, and the industry urgently needs to break through a series of new challenges based on the characteristics of new energy.
Systematic challenge, in urgent need of digital enabling full life cycle solution
New energy power generation, represented by solar power generation and wind power generation, is characterized by natural randomness, volatility and intermittency, which requires the power system to maintain short-term power balance and long-term power balance, bringing multiple challenges to the safe and stable operation of the power system.
From the power supply side, with the increase of installed permeability of new energy represented by wind power and photovoltaic, wind power has the "inverse load" characteristic of low in daytime and high in evening, while photovoltaic has the characteristic of high in daytime and no at night, so it cannot maintain stable output, which will greatly increase the stability risk of power grid. On the grid side, more and more distributed new energy access of the distribution network, also greatly test the resilience of the distribution network. From the point of view of power demand, the difference between peak and valley load of our power network increases year by year. With the development of cities and the deepening of the degree of electrification, electric energy replacement in the industrial field and the increase of electric vehicle ownership in the field of transportation will break the original relatively stable law of electric energy demand, which mainly focuses on industrial and residential electricity consumption, which will further amplify the impact of new energy access on the stability of the power system.
It can be seen that the challenges brought by new energy are systemic challenges that run through the whole link of the charge and storage of the source network, and the related problems are interlinked and contain each other. Therefore, in order to meet the challenges, digital technology needs to be fully utilized to make a comprehensive layout from the perspective of covering the whole life cycle, and go deep into every link, break through the level one by one, and finally realize the linkage to break the game.

Safety and green are prerequisites
New power systems require far more reliability of new energy generation systems, which requires power generation projects to take safety as the top priority in operation. On the one hand, the large-scale fan and the special industry attributes of high construction cost of offshore wind power put forward higher requirements for the performance and reliability of electrical products. On the other hand, because large scenery bases are often built in high altitude, sea, desert and other areas, harsh environment, coupled with electrical equipment sensitive to the environment, the performance and durability of power generation components is the key to support the source power of the new energy industry. In addition, to address the security challenges of the production end of the new energy industry, Schneider Electric provides different product portfolios and solutions for various power generation scenarios such as wind, light and storage.
Continuous product quality, Schneider Electric through innovation and agile research and development, to the new energy industry to provide safe and durable, high performance and value for money components and products, effectively ensure the reliability of new energy power generation system. Taking the new generation of TeSys F special contactor for wind power industry as an example, Schneider Electric takes the lead in upgrading 1140V high voltage, so that professional contactor products can achieve high altitude voltage without falling capacity. Meanwhile, with strong durability, through harsh environment, salt spray, vibration, high and low temperature and other severe tests, to build a stable "foundation" for safe and reliable operation in various power generation scenarios. For the special application scenario of offshore wind power, Schneider Electric's MVS TA8 series 1380V isolation switch can withstand up to 30g impact load, salt spray standard up to level 1, corrosion resistance to C4, adapt to the harsh environment at sea.While the rapid expansion of clean energy promotes the green transformation of the industry, the "green" degree of the new energy electrical equipment itself is equally important. As an advocate, practitioner and enabler of sustainable development, Schneider Electric achieves low carbon product supply based on its deep advantages in green manufacturing. Adhering to the concept of green design, Schneider Electric integrates the concept and technology of energy saving, low carbon and improving resource recycling from the beginning of product design, which not only makes the product meet the reliability of function and manufacturing process, but also provides the methodology of applying the whole life cycle analysis problem.

Multi-dimensional challenges, ecological innovation is the permanent driving force for sustainable development
< P > Under the "two-carbon" goal, the new energy industry is facing multi-dimensional challenges, not only facing the speed challenge under the carbon reduction goal, but also facing the cost challenge under the economic proposition, more to consider the social challenge of balancing demand and economic development in the energy reform. Therefore, the industry needs a more open atmosphere to break through the cooperation of all links in the industry, and seek breakthroughs through innovation. Through joint innovation and agile development, Schneider Electric and Mingyang Group to carry out close cooperation, jointly promote the implementation of innovative technology. The two sides signed a memorandum of cooperation in March 2021, committing to deep cooperation in joint product research and development, joint development of industry standards and new business models.
