For many years, domestically distributed energy, which is “acclaimedâ€, is ushering in new opportunities in a series of new changes.
“A number of factors are reshaping the future of China's distributed energy development. These factors can accelerate the application of modern distributed energy systems if they are complemented by appropriate policies, markets, and regulatory frameworks.†IEA and China Energy Network on the 30th. Yu Jing’s report on “China's Distributed Energy Outlook†is a judgment.
Among the above-mentioned favorable factors, the report considers that the most important thing is that China's current economic restructuring has an impact on energy demand, and today's economic structure is more conducive to the promotion of distributed energy. With the increase in the proportion of the tertiary industry in China's economy, the large-scale centralized energy demand from the heavy industry sector has decreased, and the economy that depends more on business and services has become more decentralized.
Second, compared to a coal-based centralized energy system, modern distributed energy systems can optimize the combination of renewable energy resources, clean fossil energy resources, significantly reduce greenhouse gas emissions, mitigate air pollution, and adapt to new environmental protection. Standard and clean low carbon development concept.
In addition, with the development of new technologies, digital sensors and control devices are widely used, and new types of loads such as big data and electric vehicles are reshaping distributed energy systems. For example, by collecting and analyzing the precise data of energy consumption, the design of distributed energy projects can be improved to better meet the needs of customers; and modern IT technologies can be combined with intelligent terminals (such as electric vehicles or thermal energy storage) to provide new services, etc. . This makes distributed energy systems more and more popular with users.
The report shows that in our country and around the world, new distributed energy business models are emerging, and new business opportunities are constantly being derived.
"Distributed energy has the characteristics of high utilization efficiency, low environmental negative impact, good economic returns, and high reliability of energy supply. It is an important direction for future energy development and will play an important role in the transformation of the power system." National Energy Administration New Energy and Zhu Ming, Director of the Renewable Energy Division, said that in particular, a service-oriented, flattened integrated energy supply method for distributed energy sources will help improve the characteristics of renewable energy grid connection, improve system operation efficiency, and promote energy production and consumption. change.
However, according to industry insiders, many years ago, due to the multiple challenges of economy, technology, and supervision, the development of distributed energy in China has frequently suffered setbacks. For example, clean energy does not have a price advantage over coal; it is difficult for distributed energy projects to obtain reasonable gains from the sale of electricity to the grid, and the positioning and responsibilities of grid companies and distributed project operators are unclear, which seriously hampers distribution. Promotion of energy projects.
Taking distributed natural gas as an example, the report data shows that as of 2015, there are about 121 distributed natural gas projects in China, and the total installed capacity is only about 1.4 million kilowatts, which is far below the national development target.
In response to these challenges, during the “Thirteenth Five-Year Plan†period, the country further increased support for distributed energy development. In May 2017, the National Energy Administration issued the Notice on Accelerating the Construction of Decentralized Access to Wind Power Projects, clarifying the basic principles for optimizing the layout of wind power, exploring the efficient development of decentralized wind power, and promoting the rational use of decentralized wind energy resources. . In June 2017, the National Development and Reform Commission issued the "Opinions on Accelerating the Use of Natural Gas" and proposed major policy measures to promote the use of distributed natural gas.
“At present, we are studying the implementation of a direct market mechanism for the distributed generation of electricity to explore new development models for distributed generation.†Zhu Ming said, it can be predicted that China's distributed energy will enter a new stage of development in the coming period.
According to the “13th Five-Year Plan†of energy development in China, by 2020, natural gas power generation capacity will reach 110 million kilowatts or more, of which distributed natural gas will be 15 million kilowatts; solar power generation capacity will reach 110 million kilowatts or more, and distributed photovoltaic power will reach 60 million kilowatts. the above. Compared with the current scale of development, China's distributed energy development still has much room for growth.
"Developing distributed energy is an inevitable requirement for solving the major contradictions in the energy field in the new era." Feng Liwen, director of the Distributed Energy Professional Committee of the China Energy Research Institute, said that it is believed that in the future, distributed energy sources may not only become a pity in China but also follow the trend. "One Belt One Road" toward a broader overseas market.
With Push-in connection technology, you can connect conductors easily – both directly and without tools, insert forces reduced by 50%. it is suitable for various applications. Insert rigid conductors or conductors with ferrules from 0.25mm² into the conductor shaft.The contact spring opens automatically and provides the required pressure force against the current bar.
When installing smaller conductors from 0.14mm², use a standard screwdriver to push the orange button and actuate the contact spring.
Push-in Connection have test and passed various certificates. For example, Vibration resistance in accordance with railway standard DINEN50155,shock and corrosion resistance in accordance with current shipbuilding registers.
