Distribution network construction should be integrated with low-carbon development

Low-carbon is one of the most concerned development models in the world today, and low-carbon development has become an important part of new urbanization. As an important foundation for the service-based new urbanization construction and development, how to integrate the distribution network planning and construction with urbanization and low-carbon development is an issue that must be highly regarded and must be analyzed in depth.

The theme communication activities of “New Urbanization and First-rate Distribution Network” jointly organized by Yingda Media Group and Shandong Electric Power Company were held on October 17 in Qingdao, Shandong. At the event, more than 200 people from the Shandong Provincial Development and Reform Commission, the National Renewable Energy Center, power supply companies, some research institutes, equipment manufacturing companies, and mainstream media explored methods and paths for distribution network service for low-carbon development and urbanization development strategies.

“We look forward to building a platform through thematic communication activities and responding to the country’s and major strategic deployments in a timely manner. Through the sharing of research results and exchange of practical experience, we will understand the overall layout of the distribution network planning and construction of the State Grid Corporation of China. Accurately understand the function of the distribution network in the low-carbon development and low-carbon city construction, and more pragmatically find a new model for the distribution network to serve the low-carbon development and urbanization development strategy.” General Manager of the organizer Ying Da Media Investment Group Shi Yudong first said at the conference.

The event was co-hosted by Yingda Media and Shandong Electric Power Co., Ltd. and co-organized by Guangzhou Southern Power Group Science and Technology Development Co., Ltd., with the theme of “low-carbon cities calling distribution networks” as the theme, through keynote reports, case sharing, roundtable forums, etc. Establish communication and exchange platforms for government, power supply companies, equipment manufacturers, and research institutions.

Distribution network will reflect the elements of service city's low carbon development

Distribution network is the energy infrastructure in the era of low-carbon economy, and it is an important means to realize low-carbon transition. It has significant protection of people's livelihood characteristics. At present, China’s new urbanization and new rural construction are accelerating. The third industrial revolution, with the “energy internet” consisting of smart grids and distributed power supplies as an important pillar, is gestating on a global scale. The development of distribution networks is facing a new situation. .

The development of clean energy has reached consensus in the world. In China, with the construction of new urbanization, the development of clean energy has also been promoted to a certain strategic position. Sun Peijun, a researcher at the National Renewable Energy Center's Industrial Development Research Department, proposed at the meeting that according to the plan, by 2015, the hydropower installation target award will reach 290 million kilowatts, wind power capacity will reach 100 million kilowatts, and photovoltaic power generation capacity will reach 21 million kilowatts. The total energy utilization is 50 million tons of standard coal.

On the other hand, reducing the urban air pollution index, avoiding or reducing haze, and developing electric vehicles have also become important measures to improve the city's low-carbon development. By 2015 and 2020, the total number of electric vehicles in China will reach 500,000 vehicles and 5 million vehicles respectively. The distribution network in some regions will have to bear the rapid increase in the charging load of electric vehicles. This will require strengthening planning and design, access management, and standardization. Construction and other work.

As an advanced stage and technical form of the smart distribution network, the planning, technology research and development and application of the active distribution network are in active development. Han Feng, deputy dean of the State Grid Beijing Institute of Economics and Technology, said that with the development of active distribution network technology, the future distribution network will effectively integrate distributed power, support up to 100% of the distributed power penetration, and have good With self-healing capabilities, the quality of power supply is significantly improved, and it can provide uninterrupted high-quality power for special users.

Han Feng said: "under the premise of supporting, welcoming, and serving distributed power generation and ensuring the full integration of distributed power supply in time, facing the large-scale access to distributed power and diversified loads, power distribution The network planning and construction must adhere to unified planning and unified standards, implement modular design and standardization construction, and actively guide the coordinated and healthy development of distributed power sources, diversified loads and distribution networks, and therefore, smart distribution networks should better reflect services in the future. Urban low carbon development elements."

Han Feng said that at present, the State Grid Corporation of China has issued a number of distributed power supply access distribution network related technical regulations on the basis of repeated research, a large number of investigations, and multi-party consultations to provide convenient and high-quality grid-connected services for distributed power supplies. And in the process of grid acceptance, access system plan development, access system engineering design review, energy meter installation, contract and agreement signing, grid acceptance and commissioning, etc. Online service work is carried out in a timely and efficient manner.
