Currently, the world is accelerating the transition to clean energy.
For China, accelerating the construction of a new energy system has been included in the government work report for two consecutive years, which means that China will further promote the energy revolution in the future.
However, in the process of switching from traditional energy to renewable energy, how to continue to play the role of traditional energy while vigorously promoting technological innovation and developing new energy is a difficult problem for many enterprises and even local governments.
For Shanghai Electric, which has a history of more than 120 years, it provides a unique low-carbon answer sheet when exploring where traditional energy goes and where new energy comes from.
Traditional energy equipment field: examples of companies that established first and then broke through the energy transformation
As of 2023, China's coal-fired power installed capacity will drop below 40% for the first time.
However, thermal power generation accounts for nearly 70% of the total power generation.
This means that thermal power is still the main power source of current domestic power supply.
Industry experts believe that although the increase in new energy installed capacity has brought about an increase in power generation, it has not increased the effective capacity of the power system.
The relevant business leaders of the New Energy Development Department of Shanghai Electric Group also expressed similar views.
He said that although wind power and photovoltaic installed capacity are large, the actual power generation is less than 15%. "When new energy cannot supply enough power, traditional energy is needed to cover the bottom."
It is the broad consensus among domestic enterprises and the industry to establish first and then break, and to promote energy transformation in a steady and orderly manner.
The gradual withdrawal of traditional energy must be based on the safe and reliable replacement of new energy.
The relevant person in charge said that in the energy field, Shanghai Electric is actively assisting the construction of new energy systems, and through improving the quality and efficiency of traditional energy equipment and optimizing the combination of energy, it is contributing to the overall improvement of the safety, reliability, and economy of the power system. .
As a member of China’s high-end equipment manufacturing “national team”, Shanghai Electric firmly promotes the development of new quality productivity.
On the one hand, we will consolidate and improve our core competitiveness in advantageous fields such as thermal power and nuclear power, and actively serve the latest requirements of the "three-reform linkage" with a system solution approach. Relying on continuously optimized energy-saving technology, we can achieve coal consumption in power supply through a variety of technical routes. Reduce the energy saving target to below 300 g/kWh.
Guangdong Guangdong Dataishan Unit 2's parameter-upgrading and efficiency-improving renovation project is the country's first "three-reform linkage" project for a 600-megawatt subcritical coal-fired unit. After the transformation, the performance test results show that the coal consumption of the unit's power supply dropped from 314.52 g/kWh. to 288.58 g/kWh.
Guangdong Yuebaishan Unit 2’s parameter-upgrading and efficiency-improving renovation project is the country’s first “three-reform linkage” project for a 600-MW subcritical coal-fired unit.
On the other hand, Shanghai Electric actively promotes the optimized combination of traditional energy and new energy in order to build a new energy system.
In March 2021, Shanghai Electric installed and configured corresponding energy storage devices in the Yangxi Power Plant project that previously provided a full set of auxiliary and main equipment for electromechanical furnaces.
In November of the same year, the project was officially connected to the grid, which not only greatly increased the frequency regulation capacity of the power plant, but also provided a buffer for large-scale grid connection of wind power, photovoltaic and other projects in the region. The following year, it became the thermal storage combined regulation with the highest frequency regulation performance in Guangdong Province. project.
Guangdong Yangxi frequency modulation energy storage power station project uses Shanghai Electric's highly safe and fast-responding power lithium iron phosphate energy storage system to effectively improve the comprehensive frequency modulation performance index and automatic power generation control level of thermal power units.
Not long ago, the first prototype of the 300-megawatt F-class heavy-duty gas turbine with the highest power and highest technical level independently developed by China rolled off the assembly line for the first time. The prototype was manufactured by Shanghai Electric General Assembly, which is of great significance to ensuring energy security and green development.
Emerging energy equipment field: vigorously develop new energy technology and equipment manufacturing capabilities
Where does new energy come from?
For Shanghai Electric, new energy mainly comes from Shagohuang, from the sea, by the wind, and by the sun...
In the field of wind power, Shanghai Electric has ranked first in the country in terms of newly installed offshore wind power capacity for eight consecutive years. It provides customers with supporting full life cycle solutions for wind power and develops new application scenarios such as "wind power +", offshore floating wind turbines, and wind-fishing integration. .
In the field of photovoltaics, Shanghai Electric combines heterojunction photovoltaic equipment production lines with cell and module end product technologies, reaching the industry-leading level; in the field of photothermal technology, the Dubai photovoltaic photothermal power station project undertaken by Shanghai Electric is one of the world's largest The solar thermal photovoltaic composite power generation project with the largest installed capacity and the highest technical standards has provided experience for Chinese companies to go overseas.
The fourth phase of the Dubai Maktoum Solar Park 950MW solar thermal photovoltaic hybrid solar power station project is contracted by Shanghai Electric. It can achieve 24-hour continuous power generation with 100% renewable energy and can reduce carbon emissions by 1.6 million tons per year.
In the field of hydrogen energy, based on its technological accumulation in high-end equipment manufacturing and system integration, Shanghai Electric can provide full industry chain solutions for the four major links of hydrogen energy "production, storage, addition, and use", and has built the first domestically applied industrial The park’s “green hydrogen production-storage-use” integrated demonstration project.
It is worth noting that the randomness, intermittent, and volatility of new energy power generation pose challenges to the stable operation of the power grid.
As the installed capacity of new energy continues to increase, how to store it has become an urgent problem to be solved.
Relying on its comprehensive equipment advantages, Shanghai Electric has laid out multiple energy storage technology routes such as compressed air energy storage, pumped hydro energy storage, flywheel energy storage, lithium battery energy storage, and liquid flow energy storage to build a coordinated development ecology of multiple energy storage industries and serve as a foundation for the power supply side. , power grid side, industrial and commercial side, etc. to provide one-stop "optimal storage" system solutions.
Based on the rapid development of new energy technologies and equipment manufacturing capabilities such as wind, solar and hydrogen storage, Shanghai Electric is striving to create "all-round" new power system solutions and "three-dimensional" zero-carbon park system solutions to fully tap its role in "source, grid and load" The core equipment advantages of "storage and control" can simultaneously meet the green and low-carbon development needs of the energy supply side and energy consumption side, realize the integrated coordination of "source grid load storage", and promote the implementation of the new energy security of "four revolutions and one cooperation". Strategy contributes corporate wisdom.
Last year, Shanghai Electric mentioned in its first "Shanghai Electric Group "Double Carbon" Action Plan" that it would strive to achieve carbon peak before 2030, achieve carbon neutrality in its own operations before 2035, and achieve carbon neutrality in the entire value chain by 2055. neutralize.
Based on the realization of its own "double carbon" goal, it will help industry customers achieve green and low-carbon transformation and development.
2024 marks the 75th anniversary of the founding of New China and is also a critical year for achieving the goals and tasks of the 14th Five-Year Plan.
During the critical period of energy low-carbon transformation, it is necessary to accelerate the construction of a new energy system on the basis of maintaining the bottom line of energy security.
"Energy transformation is a long-term process. In the future, we will carry out combined innovation for application scenarios and promote the upgrading of individual equipment to integrated equipment system solutions." said the relevant person in charge of Shanghai Electric.
