Fu Xin stopped, and the two bigwigs, Zhou Zhengming and Gao Wenxin, began to ponder.

After a while, Zhou Zhengming asked: "What kind of construction conditions do you need for this smart grid?" ”

"The construction conditions are ......," Fu Xin said in a deep voice: "Regarding this construction condition, I didn't think about it carefully, after all, our country's current power grid is not ...... Perfect, blackouts are a regular occurrence......"

Fu Xin saw that Zhou Zhengming and Gao Wenxin's faces remained unchanged, so he continued: "Therefore, I will only consider the construction conditions of a smart grid model based on a strong power grid based on the UHV power grid as the backbone grid and the coordinated development of the power grid of various voltage levels, which I call the construction conditions of a strong smart grid." ”

"Tell me about it." Zhou Zhengming signaled.

Fu Xin nodded and said in a deep voice: "First, in terms of grid construction, we must continuously strengthen and improve the grid structure, and make the UHV AC test demonstration project and UHV DC demonstration project successfully put into operation and operate stably; It is necessary to fully grasp the core technology of UHV power transmission and transformation to lay a solid foundation for the development of the power grid.

Second, in terms of operation and control of large power grids, it is necessary to have the institutional advantages of 'unified dispatching' and rich experience in operation technology, the level of dispatching technology and equipment should be at least internationally leading, and the self-developed dispatching automation system and relay protection devices should be widely used.

Third, in terms of the construction of communication information platform, the power communication backbone network of 'three vertical, three horizontal and one ring network' will be built, and a communication network pattern with optical fiber communication as the mainstay and microwave, carrier and other communication modes coexist; The SG186 project should achieve phased results, and the business application systems such as ERP, marketing, and production should complete the pilot construction and begin to be popularized and applied on a large scale. ”

Speaking of which, Fu Xin was very puzzled when he saw Zhou Zhengming and Gao Wenxin. Immediately reacted to the fact that he had leaked his mouth, so he explained: Uh...... I'm a little embarrassed to say. "This 'three vertical, three horizontal and one ring network' and the SG186 project are named by myself.

'Three vertical, three horizontal and one ring network' refers to the energy bases of Mengxi, Simon, Beizhang and Beishan to transmit power to North China, East China and Central China through three longitudinal UHV AC channels, and North China Coal Power and Southwest Hydropower to North China, Central China and Yangtze River Delta UHV Ring Network through three horizontal UHV AC channels.

Thereinto. The three verticals are: Mengxi to Jinling, Beizhang to Hongcheng, and Northern Shaanxi to Shachang. The three horizontal transmission channels are: Simon-Fangwei, Zhongjin-Zhouxu, and Anya-Nanwan. In addition, it has also built a UHV double ring network in the Yangtze River Delta of Nanhuai-Jinling-Zhoutai-Zhousu-Haihai-North Zhejiang-Southern Anhui-Nanhuai.

The SG186 project refers to the use of '1' platform, '8' large application, '6' system to weave our national grid "longitudinal through, horizontal integration" of the huge information network, so I named it SG186 project.

Among them, the "1" in the "SG186 project" refers to the integrated enterprise-level information integration platform. After the construction of this platform is completed, it will have a unified data exchange function, so as to achieve 'one entry, multiple uses', and provide guarantee for the authenticity, consistency and integrity of data.

At the same time, the platform also undertakes to smooth the information channel. Promote business integration, integrate existing application systems, avoid duplicate construction, reduce development costs, eliminate information "islands" and other roles, and realize data sharing in production, operation, management and other links, and establish a series of functions such as enterprise global data dictionary.

The "8" in the "SG186 Project" refers to the eight business applications of construction financial management, marketing management, safety production management, collaborative office management, human resource management, material management, project management and comprehensive management. Through integration, improvement, renovation and new construction, data sharing between applications is realized. It will greatly improve the quality and efficiency of the work.

The "6" in the "SG186 Project" refers to the need to "establish and improve the six information support systems".

These six systems are: information security protection system, standard and specification system, management and control system, evaluation and assessment system, technical research system and talent team system. These systems provide the necessary resources, technology, management and human resources. ”

Zhou Zhengming and Gao Wenxin digested Fu Xin's advanced thoughts, and motioned to Fu Xin to continue, Fu Xin continued: "I will continue to talk about the construction conditions of the smart grid before!

Fourth. In terms of testing and testing methods, it is necessary to set up large-scale wind power grids, solar power generation and electricity technology research and testing centers according to the needs of the development of smart grid technology.

Fifth. In terms of smart grid development practice, the pilot work of all links should be carried out in an all-round way. Smart grid dispatching technical support system, intelligent substation, power information collection system, distribution automation, power fiber to the home and other projects should be implemented.

Sixth, in terms of large-scale renewable energy integration and energy storage. It is necessary to carry out in-depth research on key technologies such as centralized grid connection and electrochemical energy storage, establish a simulation and analysis platform for wind power access to the power grid, and formulate relevant technical standards for wind farms to access the power system.

Seventh, in terms of the power grid development mechanism, the business scope of China's power grid sector should cover all aspects from transmission, substation, distribution to electricity consumption, and there should be obvious advantages in unified planning, unified standards, and rapid advancement.

Oh, by the way, Minister Zhou, Minister Gao, about this construction condition, I made a pyramid diagram, which can clearly reflect the framework of the construction conditions of a strong smart grid. ”

After speaking, Fu Xin turned a piece of paper handed over by Secretary He, and drew it on it, and after a while, Fu Xin drew a six-layer pyramid-shaped framework of construction conditions, and wrote "one goal, two main lines, three stages, four systems, five connotations, and six links" on the frame from high to low.

One goal - to build a unified and strong smart grid with UHV as the backbone grid and the coordinated development of power grids at all levels;

Two main lines - technology, automation, interaction, management, collective, intensive, lean, standardization;

Three stages - planning pilot stage, comprehensive construction stage, leading and upgrading stage;

Four systems - power grid basic system, technical support system, intelligent application system, standard and specification system;

Five connotations - strong and reliable, cost-effective, clean and environmentally friendly, transparent and open, friendly interaction;

Six links - power generation, transmission, transformation, distribution, power consumption, and dispatching.

"For the three stages and five connotations, let me make a simple explanation!" Fu Xin said after drawing the map: "In the planning pilot stage, we will focus on the preparation of smart grid development plans, formulate technical and management standards, carry out key technology research and development and equipment development, and carry out pilot work in all aspects;

In the comprehensive construction stage, the construction of UHV power grids and urban and rural power grids will be accelerated, and a smart grid operation control and interactive service system will be initially formed, and major breakthroughs and wide applications will be achieved in key technologies and equipment;

Leading the improvement stage, building a unified and strong smart grid in an all-round way, so that the resource allocation capacity, security level, operation efficiency of the power grid, as well as the interaction between the power grid, power supply and users have been significantly improved.

Strong and reliable, that is, it has a strong grid structure, strong power transmission capacity and safe and reliable power supply;

Cost-effective, that is, to improve the efficiency of power grid operation and transmission, reduce operating costs, and promote the efficient use of energy resources and power assets;

Clean and environmental protection, that is, to promote the development and utilization of renewable energy, reduce energy consumption and pollutant emissions, and increase the proportion of clean electricity in final energy consumption;

Transparency and openness, that is, the information of the power grid, power supply and users is shared transparently, and the power grid is open without discrimination;

Friendly interaction, that is, to realize the flexible adjustment of the operation mode of the power grid, friendly compatibility with the access and exit of various power sources and users, and promote the active participation of power generation enterprises and users in the operation and regulation of the power grid. ”

"Broadly speaking, smart grids include smart dispatch systems that prioritize the use of clean energy, smart metering systems that can be priced dynamically, and smart technology systems that optimize load balancing by adjusting the power of power generation and consumer equipment.

With the construction of smart grids, electric energy can not only flow from centralized power plants to transmission grids, distribution networks and even users, but also various forms of new and clean energy in the power grid: solar energy, wind energy, fuel cells, electric vehicles, etc.;

In addition, the high-speed, two-way communication system can realize the information exchange between the control center and the power grid equipment, and the advanced analysis tools and decision-making system ensure the safe, stable and optimal operation of the smart grid.

The goal of smart grid is to achieve reliable, safe, economical, efficient, environmentally friendly and safe use of the power grid.

Smart grids must be more reliable – smart grids can provide a reliable supply of power to users wherever and whenever they are needed. It provides sufficient warnings of possible problems in the grid and can tolerate most grid disturbances without power outages. It enables effective corrective action to be taken before consumers are affected by power outages, so that grid users are protected from power interruptions.

Smart grids must be more secure – able to withstand physical and cyber attacks without widespread outages or costly restoration. It is less susceptible to natural disasters.

Smart grids must be more economical – smart grids operate under the basic law of balance between supply and demand, at fair prices and with sufficient supply.

Smart grids must be more efficient – smart grids use investments, control costs, reduce losses in power transmission and distribution, and make power production and asset utilization more efficient. Through the control of power flow methods to reduce transmission power congestion and allow for the integration of low-cost power sources, including renewable energy.

Smart grids must be more environmentally friendly – smart grids reduce environmental impact through innovations in power generation, transmission, distribution, energy storage, and consumption. Further expand access to renewable energy. Where possible, in future designs, smart grid assets will occupy less land, reducing the physical impact on the landscape.

Smart grids must be safe to use – Smart grids must not harm the public or grid workers, i.e. the use of electricity must be safe. (To be continued......)
