Full Solution National Grid Launched 6 Types of Smart Grid Demonstration Project

“Six smart grid innovation demonstration projects not only reflect the latest concept of the company's smart grid construction, but also an innovative practice in which the company extends the service value of the grid further to the society.” Shen Jiang, Deputy Director of the Ministry of Science and Technology (Smart Grid Department) of the State Grid Corporation of China When interviewed by reporters, said.

Not long ago, the company formally launched the demonstration project of smart grid innovation. The project focuses on six areas, including new energy development, distributed power application, convenient electricity use, electric vehicles, smart cities, and smart grids, which are widely concerned by the society, and has created a number of international leading smart grid projects and highlights projects. Accelerate the transformation of energy production methods and consumption patterns.

Shen Jiang admits that with the transformation of the world's energy structure, the power grid has gradually changed from a traditional power transmission infrastructure to a platform for all types of energy conversion and efficient deployment. Based on the needs of the economic and social development of services, realizing various power supply mutual compensation adjustments, providing differentiated services for the society and consumers, and exploring new business models are the core goals and important tasks of this demonstration project of smart grid innovation.

"State Grid": In the implementation plan of the company's six types of smart grid innovation demonstration projects, there are five types of projects that are the focus areas that are based on the widespread concern of society and universal awareness. Excuse me, what kind of strategic considerations is based on such a deployment?

Shen Jiang: Since the company first proposed smart grid construction in China in 2009, after years of development, it has achieved a series of important achievements in smart grid technology, standards, equipment, and construction. At the same time, as economic and social development drives the continuous growth of energy demand, environmental protection and the pressure on foreign energy dependence will gradually increase. In particular, the country proposes to promote the “revolution” of energy consumption, energy supply, energy technologies, and energy systems. Smart grid construction faces new challenges.

First of all, China's new energy has entered a period of rapid development. Wind power and solar energy will be scaled up and will be developed in the direction of more extensive fields such as distributed generation and marine wind power. How these new energy sources can better integrate with the grid construction planning, how to scientifically conduct regional layout, whether key technical problems can be solved, and how to further innovate in business operation models all require active research and breakthroughs.

Secondly, the task of energy conservation, emission reduction and haze management is very urgent. At present, many cities in the country continue to haze, which seriously affects the residents' living environment and physical health. Harnessing haze will inevitably bring about changes in energy use and consumption patterns. For example, as an effective vehicle for controlling haze, electric vehicles are entering a stage of rapid development, and customers' demand for electricity will be diverse and individualized. Smart grid construction must adapt and meet this change and needs.

The third type of new urbanization construction is on track. The state has already set clear goals and specific requirements for the new type of urbanization. It can be predicted that the future economic and social development will rely more on electricity. Taking the intensive, smart, green, and low-carbon new urbanization road will inevitably require the concept, planning, and technology of smart grid construction to meet the needs of new urbanization construction, and constantly amplify and extend the social service function and value of the grid.

In the end, the substitution of electrical energy can not be delayed. The implementation of electrical energy substitution and optimization of energy structure are inseparable from the development of a strong smart grid. The power grid is the basic carrier of power transmission. The development of new energy sources, the realization of large-scale optimization of green power consumption and the two-way metering measurement will inevitably require the power grid to have powerful energy conversion, efficient configuration and interactive service functions. Smart grids can greatly increase the efficiency of energy production, conversion, transportation, and use, enhance the security, economical efficiency, reliability, and environmental friendliness of energy supply, and promote sustainable economic, social, and environmental development.

It is in this context that the company proposes to reorganize smart grid construction concepts, adjust smart grid construction plans, and deploy new innovative demonstration projects for smart grids. It requires two years to complete the important task of building six types of innovative demonstration projects.

National Grid: We have noticed that there are many projects in the six types of innovative demonstration projects that involve future development potential. What is the purpose of selecting these forward-looking projects?

Shen Jiang: At present, the concept of development of the company's smart grid has become more and more the same with the world, that is to pay more attention to large-scale optimization of energy resources, pay more attention to the new energy access and demand-side intelligence, but also pay more attention to integration into In all aspects of society and in the lives of the public.

When the company's six innovative demonstration projects are designed from the beginning, it is to consider and plan for the development trend of the power grid in the next five to ten years, and more is to explore what the future service model of the power grid is.

For example, how to guide electric vehicle users to avoid the peak period of electricity consumption and reasonably choose time charging; adopt a more flexible price mechanism to encourage customers to use peak power at different peaks; how to implement smart grids such as car networking and internet of things. We not only hope to solve the technical difficulties of smart grid construction through engineering construction, but also hope to further innovate the business model of smart grid operation through exploration and practice, and study and seize the new service forms and opportunities of the smart grid in the future.

"State Grid": What is different from the past is that the six types of innovative demonstration projects are reported by the provincial companies themselves and are responsible for construction. The company's Ministry of Science and Technology is responsible for the top-level design. Does this reflect that the overall strength of the company's smart grid construction is more balanced?

Shen Jiang: The company's past smart grid projects are mainly the headquarters and the company's scientific research institutions to play more power. Provincial companies have the will to build but lack experience and technology. After several years of development, the company's system units have become increasingly sophisticated and professional in terms of smart grid construction concepts, project implementation arrangements, and technologies. Of the six types of innovative demonstration projects, more than half of the projects are provincial company planning organizations. The company's headquarters is responsible for the top-level design and the company's research institutes. It considers and integrates the project's demonstration, promotion, and economic value.

This combination of bottom-up and top-down approach makes the project more “local” and more exemplary.

For example, State Grid Jilin Power proposed to integrate wind power in Northeast China with urban heating to effectively solve the problem of wind power consumption; State Grid Tianjin Power proposed that it would try to use new smart grid technologies and new technologies in the second phase of the Tianjin Eco-City project The business model explores the new service operation model of the smart grid in the next 10 years. Local companies near the coast and along the river propose marine shore power projects. These projects are in line with local needs, have a high degree of social attention, and are applied. The latest technology of the smart grid has outstanding project demonstration features and has the value of practical promotion to other regions of the same type.

"State Grid": What are the technical challenges for the new round of smart grid construction?

Shen Jiang: The technical challenge is encountered at any time. Many of the six types of innovative demonstration projects are focused on long-term development plans for the power grid, and there will inevitably be many technical challenges. Offshore wind farm demonstration project is an example.

At present, domestic offshore wind farms are mainly concentrated in Jiangsu and Shanghai, and wind resources in the southern coastal areas are better. However, typhoons and other bad weather are often encountered in the southeast coastal areas. This is a test for the location, layout, and delivery of wind power. We hope that through the construction of demonstration projects for offshore wind farms, we will study whether wind power can be further developed to the south, such as large-scale development and the laying of submarine cables.

In addition, there are problems with business models. In June of this year, when the 6th meeting of the Central Financial Leadership Group proposed the energy revolution, it also mentioned the direction of green and low carbon, and promoted technological innovation, industrial innovation, and business model innovation. For us, business model innovation is the biggest challenge. Without establishing an ideal business model, the advantages of technology can not fully play its role. In the innovative demonstration project, we have determined that electric vehicles, marine shore power, smart cities and other projects are precisely efforts to explore and solve future business models.

"State Grid": Does the project represent the future development direction of the company's smart grid?

Shen Jiang: In 2009, the company proposed the construction of a smart grid for the first time. At that time, the company focused on the construction of six major links: power generation, transmission, substation, dispatch, distribution, and power supply. It focused on smart dispatching, smart substations, and transmission and transformation equipment monitoring. Power distribution automation, such as the construction of the power grid itself. The innovation demonstration project is mainly based on a wide range of social concerns, considering the rapid development of distributed power and other situations and the purpose is to promote the accelerated transformation of energy production and consumption patterns.

In terms of this change, the company’s smart grid construction, whether it is from the concept or the specific project, is actively considering or even ahead of time considering the needs of economic and social development and the development of the power grid itself. It is a long-term project of continuous innovation and innovation. . At present, various new technologies and new applications have emerged in endless forms, such as electric vehicles, which are new products that combine new energy with the traditional automotive industry.

Therefore, I believe that the demonstration and demonstration of the Category 6 Smart Grid Innovation Demonstration Project reflects the direction of the company's smart grid construction in the future. However, whether the future development will follow this path will also depend on the external environment and the company's own development strategy. In short, smart grid construction also needs to be adjusted and refined at different stages of development to make it truly fit for development needs.
