Double carbon target promotion, ABB renewable energy technology boosts the construction of new power system

At present, air pollution, water and soil loss, greenhouse gas effect and other ecological and environmental problems caused by traditional non clean energy have become increasingly serious, and the transition of clean and renewable energy has reached a critical time window. At the same time, nearly 200 economies in the world have reached the Paris Agreement, and China, Japan, France, Spain and other countries have successively passed low-carbon transition laws. The pace of global "carbon neutrality" is unstoppable.



Building a new power infrastructure with new energy as the main body has become the focus of the industry, and the installed capacity of wind power, photovoltaic and other new energy equipment will be greatly improved in a long period of time in the future. According to the Plan of China's Renewable Energy Development Roadmap 2050 of the Energy Research Institute of the National Development and Reform Commission, the proportion of renewable energy power generation will reach 86% in 2050, and the prediction of the International Renewable Energy Agency is basically consistent with the goal of our government.

Industry leading demonstration, how about the development of new energy power generation installation efficiency and technology level?



In the past decade, solar photovoltaic has been the fastest growing new energy in the world. As the concept of low-carbon sustainable development continues to be deeply rooted in the hearts of the people, the scale of global solar energy development and utilization is rapidly expanding, and the technology continues to progress, showing a good development prospect. Photovoltaic industry is emerging in Europe, with China as the latecomer, and the global parity market. Its installed cost continues to decline, driving the improvement of power generation cost performance, and becoming an important driver of the transformation and upgrading of new energy.



ABB has a long history of research and development in the photovoltaic field. It has participated in the development of almost every kind of photovoltaic power generation (PV) and concentrated solar energy (CSP) technology, and can provide a wide range of comprehensive product, system and solution combinations. For example, E90 PV fuse holder and fuse, MCB S800PV-SD high-performance disconnector, insulation monitoring relay and other innovative products have been successfully applied to many landmark projects in Europe, North America, Asia and other regions.

In addition to solar photovoltaic, wind power development is also surging, but we have to admit that the primary task of large-scale application of wind power is to solve the problem of wind power development in terms of wind turbine technology, wind power prediction technology, wind power grid connection technology and energy storage technology. In this process, ABB can also provide medium and low voltage products including circuit breakers, contactors, molded case circuit breakers, medium voltage circuit breakers, ring network cabinets, environment-friendly safe air distribution cabinets, and ABB Ability ™ EDCS intelligent power distribution management system and other digital schemes are applicable to the pitch, yaw, main control, converter and auxiliary systems in each wind turbine of the internal system of the wind turbine, as well as the grid connection, boost and other processes of the external system.



Siemens Gamesa, a global energy giant, has deployed ABB AF contactors in its wind power equipment. With its low energy consumption and compact industrial design, it has significantly reduced the size of the fan control cabinet and simplified the assembly process, while also reducing the cost by 20%.



On the domestic market, ABB has also provided all-round technical support for many benchmark wind power projects in the past few years, committed to localization and localization of mature experience technologies, and helped them reduce equipment costs and maximize unit power generation efficiency with extremely low life cycle maintenance costs. For example, 40.5kV gas insulated ring network cabinet equipment was provided for the first large-scale offshore wind power demonstration project in China - Shanghai Donghai Bridge offshore wind farm; Provide a complete set of electrical equipment including medium voltage gas insulated switchgear for Jiangsu Xiangshui Offshore Wind Farm; It is the first "Double Ten" offshore wind power project of CGN in China and the first 110kV offshore wind power booster station in Asia, providing medium voltage switchgear, low-voltage switchgear, etc



In the future, wind turbines will be installed with longer blades and better performance generators, and photovoltaic systems will also be equipped with modules with higher efficiency. The demand for lower solar energy cost and higher efficiency has given birth to the demand for higher voltage and more energy saving equipment. ABB's photovoltaic application portfolio focuses on providing continuous operation, higher reliability and return on investment, enabling customers to make full use of savings by using 1500V DC and 800V AC technologies, which helps to improve the efficiency of "system electrical balance" related to power loss. The copper windings of 800V AC transformers save 14%; The 1500 V DC parallel array saves 35% and the array components 33%, delivering more power to consumers.



Solar power plants are usually located in high temperature environment or high altitude areas, which require equipment that can work normally under harsh conditions. ABB products can operate at high temperatures up to 55 ° C or 4000 meters above sea level and deliver the most reliable high-performance solutions.



Advanced digital management scheme to achieve end-to-end efficient operation and maintenance from new energy power generation to power consumption



In addition to the more economical, cleaner and safer energy structure upgrade brought by the increasing installed capacity of global new energy systems, the operation mode of the power end is also changing dramatically. The decentralization of more and more new energy production and supply modes, such as distributed energy and regional multi energy coordinated comprehensive energy, has promoted the transition of smart energy from initial single point technology research and development to systematic industrialization.



Digitalization is one of the key links to develop a stronger and more intelligent energy Internet. Its core is the multi energy scheduling algorithm. Through the economic scheduling algorithm and big data scheduling algorithm, we can improve the green energy access and consumption capacity to maximize low-carbon emission reduction. ABB Ability ™ The smart micro grid management solution combines ABB's rich experience in new energy dispatching, provides a scenario based energy combination scheme, quickly outputs targeted energy storage charging and discharging strategies and flexible load regulation strategies, and improves energy efficiency.



In addition, large-scale new energy access and micro network management require intelligent and digital means ™ EDCS intelligent power distribution management system automatically provides customers with health assessment and operation and maintenance suggestions for equipment and systems, and further realizes the overall intelligent operation and maintenance management.
