[Shanghai, China, May 23, 2023] The 16th (2023) International Solar Photovoltaic and Smart Energy (Shanghai) Conference of SNEC (hereinafter referred to as "SNEC2023 Photovoltaic Conference") was held in Shanghai from May 23 to 26. Enterprises, experts, industrial organizations, media and analysts from the energy and photovoltaic industries attended the meeting to discuss the technological development trend of the photovoltaic industry and share the latest application practices.
Today, at the conference, Hou Jinlong, president of Huawei Digital Energy Technology Co., Ltd., delivered a keynote speech on "Integrating Digital Technology and Power Electronics Technology, Promoting Energy Revolution and Building a Green and Bright Future Together". Hou Jinlong said: "The source power of the energy industry has shifted from'natural resources' to'technological innovation ', and the three-wheel drive of carbon neutrality, energy independence and commercial value is accelerating the process of energy transformation.". In the field of clean power generation, Huawei Digital Energy integrates digital technology and power electronics technology, focusing on the three scenarios of power station, industrial and commercial use and household use, through intelligent photovoltaic storage generators, "excellent photovoltaic storage and charging cloud" solutions, to build a new type of power system energy infrastructure, and accelerate photovoltaic to become the main energy source.
From "natural resources" to "technological innovation", the energy industry has rapidly entered a new era
of digital energy. Carbon neutrality has become the most definite strategy in the 21st century. The source power of the energy industry has shifted from "natural resources" such as coal and oil to "technological innovation" such as wind, light, storage, power electronics and digitalization. Driven by technology, the digital world and the energy world are deeply integrated, and the energy industry is rapidly entering a new era of digital energy, showing three main characteristics:
renewable energy as the leading factor:
the proportion of renewable energy installed will increase from 28% to 91% in 2050. Among them, photovoltaic will become the main energy source. In China, photovoltaic installed capacity has surpassed hydropower in 2023 Q1, jumping to the second largest energy source.
Take electricity as the center:
electricity will become the main body of energy consumption, and the proportion of electricity in energy consumption will increase from 22% now to 51% in 2050.
Digital technology is the key enabler:
Digitalization is accelerating the activation of energy data potential, the energy system is highly intelligent, the energy Internet with self-balancing, self-operation and self-processing will initially take shape, and new energy systems and business models will continue to emerge.
Focusing on 4T technology integration and building a new power system energy infrastructure, the core of
energy transformation is to build a "safe, reliable, low-carbon, economic" new power system, and technological innovation and industry chain synergy are the key paths. Huawei Digital Energy focuses on the integration of 4T technologies such as Bit, Watt, Heat and Battery, and builds a new power system energy infrastructure for the three scenarios of clean energy base, city and family.
● For the clean energy base, Grid Forming energy storage technology is used to build "intelligent photovoltaic storage generator", through the integration of photovoltaic, wind power and energy storage, through the integration of power electronics technology, digital technology and advanced grid-connected technology. The photovoltaic storage system has the ability to actively enhance the power grid and the function of the traditional synchronous generator, from following the power grid to actively enhancing the power grid, so that photovoltaic and wind power can be changed from supplementary charging to main power, and the energy system can be truly realized with clean energy as the main body. In the past ten years, the photovoltaic industry has witnessed the emergence and large-scale application of "intelligent string technology", and in the next ten years or even longer, it will usher in the era of "intelligent photovoltaic storage generator". Intelligent photovoltaic storage generators and the wide application of digital technology can create a high-quality, all-digital clean energy base, so that the clean energy base can move towards "automatic driving".
In view of the problems of high-carbon energy structure, contradiction between power supply and demand, and high energy consumption in cities, Hou Jinlong emphasized the need to build a green and low-carbon urban energy agent, through various distributed energy, virtual power plant VPP, intelligent charging network, V2X, integrated intelligent energy, smart micro-grid and other innovative products. To achieve intelligent collaboration of source, network, load, storage and utilization, and intelligent interconnection of thousands of distributed energy systems, an urban energy Internet based on smart grid and smart micro-grid will be built to achieve urban safety, resilience, high efficiency, low carbon and intelligence.
● For household energy scenarios, Huawei Digital Energy believes that it is necessary to build a green, low-carbon, extreme experience, intelligent and interconnected household energy management system, so that households can change from a single energy consumer to both an energy consumer and an energy producer in the new power system.
Power grid security and information security are the cornerstones
of high-quality and sustainable development of photovoltaic storage industry. As more and more photovoltaic and energy storage are deployed in parks, buildings and households, they are more closely integrated with people's production and life, and personal and property safety must be guaranteed. The industry needs to jointly promote and implement the establishment of a new power system standard system, solve the "security risks" from the root, and ensure the healthy and sustainable development of the industry.
Photovoltaic industry should take the initiative to establish safety standards jointly with relevant industry departments. For example, Europe, Australia and other regions and countries regard photovoltaic DC arc detection and rapid shutdown as standards, and all rooftop photovoltaics must have this capability. In China, the National Standard Committee and the National Energy Administration jointly issued the Guidelines for the Construction of Carbon Peak and Carbon Neutralization Standard System, which will focus on the formulation of relevant standards for the grid side, power supply side, load side and energy storage side of new power systems. The European Union has also started to modify the grid code to include the requirements for energy storage and Grid Forming.
Carbon neutralization is an extensive and profound economic and social change, which requires the whole industry and the whole society to work together and take positive actions. The digital energy industry is an ecological industry. Looking forward to the future, Huawei Digital Energy will continue to innovate in technology and products, and unswervingly work with industry and ecological partners to build a digital energy industry ecosystem, so that green energy can benefit thousands of industries and millions of households:
● & nbsp; Join hands with the world's leading customers to accelerate the development process of new power systems, new digital industry energy infrastructure and new electric travel around the scene of continuous technological innovation and application demonstration.
● Grow together with global business partners to build ubiquitous green, low-carbon and intelligent distributed energy systems.
● Work together with global clean energy industry chain partners to promote industrial development.
● Join hands with like-minded people around the world to actively promote industrial policies, industry standards, roadmaps and timetables for the realization of the dual-carbon target.
