Cities are the main body of energy consumption and determine the energy development pattern. In recent years, the rapid development of renewable energy sources is reshaping new urban energy consumption methods. At the same time, the overall energy efficiency of cities is generally low, and there is a lack of effective integration among energy systems. Linked and coordinated development, coupled with the dual pressures of internal and external environment, urgently require transformation and development. Therefore, the transformation and upgrading of urban energy development mode will not only have great significance in promoting the development of energy reform, but will also drive the upgrading and upgrading of cities.
Different cities need different kinds of energy. In recent years, local governments and energy industry companies have been actively coping with the issues of large-scale energy demand, lack of resources, serious pollution, and insufficient coordination in the process of urban transformation and development. According to the transformation and development of different cities, Demand, adopting different types of energy transformation methods, has made great contributions to accelerating the third energy revolution, vigorously developing clean energy, opening up safe, clean and efficient energy sustainable development roads, and promoting urban energy transformation and development.
In order to objectively publicize and report on the issues and achievements highlighted in recent years in China's urban energy revolution, starting from this issue, this newspaper has set up a section titled “Finding the Model of Urban Energy Reform”. It mainly focuses on the energy revolution in the city, through the 'person, Urban, corporate, project engineering, and technical products' five chapters outline the 'industry model', to play the authority of the mainstream media, professionalism and influence, to make a good record and promoter of urban energy changes.
The Central Committee of the Communist Party of China and the State Council's recently approved “Xionggan New District Planning Outline” pointed out that the company adheres to green power supply and forms a power supply method that is based on 'receiving clean electric power outside the area, supplemented by distributed renewable energy power generation in the region'. Subsequently, The network Xiong'an New District Power Supply Company was formally established. According to the plan, Xiong'an New District will fully promote electrification, and the supply side will achieve 100% clean external power. It will become the world's first urban power grid with 100% clean power supply for the whole time period. The proportion of energy consumption reached more than 52%. This reflects our country's determination to promote 'low-carbon energy transformation, urban green development'.
In fact, in recent years, many cities in China have attempted to green, low-carbon, and efficient changes in the energy supply, distribution, and consumption sectors, and have gained a lot of useful experience.
City and energy need to develop together
“You can start your home’s air conditioner on your mobile phone before work and work on the water heater. When you get home, the temperature in your home is comfortable. The hot water in the shower is also burned. It is convenient and energy-saving. 'Speaking of the convenience brought by smart home, Mr. Cheng of Tianjin Eco-city met with a look. It is understood that the Sino-Singapore Tianjin Eco-City, located in the Tianjin Binhai New Area, was jointly built by the Chinese government and the Singapore government. It is the first green comprehensive development demonstration area in China.
Walking on the Central Avenue of the Eco-City, you can see that the solar photovoltaic panels stretch for several kilometers. 'These solar energy can be directly used by residents of the community, and the rest can be stored in batteries. In addition, the public buildings in the eco-city are installed in hotels. A new energy system was introduced. 'Qin Lijie, Director of the Power Supply Service Center of the Ecological City, briefed reporters. From power shortages to 'electricity coming from afar', to energy supply inside and outside the city, energy is more intelligent, and energy and the city are becoming complementary to each other. More complete.
Li Weiyang, director of the State Grid (Suzhou) Urban Energy Research Institute, said in an interview with reporters: 'The current society, the relationship between cities and energy has undergone great changes, from the past energy supply to protect the city's development into the current energy-driven city. Development. Before the city was 'big', energy was 'small', but now we need to consider the relationship between the city and energy in parallel. Cities, energy and related industries need to develop collaboratively. Based on this, our institute proposed the concept of 'city + energy'. A non-urban energy system or a city under energy.'
To this end, in August 2017, the Jiangsu Provincial Electric Power Company, the State Grid Energy Research Institute and the Suzhou Municipal Government adopted a joint-stock system to jointly establish the State Grid (Suzhou) Urban Energy Research Institute. This is the first urban energy research institute in China, marking the China has taken a strategic step in promoting energy reform, deepening research on major issues in urban energy, and promoting the coordinated development of cities and energy.
Clean green development attracts attention
'A city that accounts for more than half of the world's population consumes more than two-thirds of the world's primary energy and generates 70% of its energy-related carbon emissions. From the perspective of energy density, the core of world-class metropolises such as New York, Paris, Tokyo and Shanghai The district's electric power load density is 16,000-2.6 million kilowatts per square kilometer, which means that only 5-8 tons of standard coal will be consumed for electricity consumption within one hour per square kilometer during the peak period. 'Li Weiyang uses a series of figures to show the city's energy efficiency. The huge dependence.
Fortunately, with the improvement of energy-saving awareness and the innovation of energy supply models, the energy production and consumption patterns of Chinese cities are undergoing major changes. The transformation of energy consumption and energy supply modes in China-Singapore Tianjin Eco-City is also becoming more and more important in China. Multi-City Realization. Taking Beijing as an example, you can clearly feel the benefits of energy structure optimization in Beijing in recent years.
"Last year in winter, there were fewer haze days. Apart from God's help, it was mainly due to the improvement of coal to electricity." Ms. Wang, who lives in Beijing's Shunyi District, feels that her coal-changing power has contributed to harnessing haze.
In March 2017, as the last coal-fired power plant was shut down and backed up, Beijing realized a coal-free power plant and became the first city in the country to achieve clean energy generation. At the same time, in the area of energy consumption, Beijing’s coal-free use of electricity is also accelerating. Advances, from coal-to-electricity in the heating sector to electric vehicle applications in the transportation sector, charging and replacing facilities, etc., covering food, clothing, housing, and transportation.
Analysing Beijing’s experience in promoting energy transformation in recent years has found that whether it is reducing coal consumption, increasing the proportion of foreign calls, increasing the use of natural gas for conversion and utilization, or promoting new energy, distributed energy development, electricity plays an important role as a hub platform. 'At present, the proportion of electricity received by Beijing is about 70%, which is the first city in the country to achieve clean energy generation. By 2020, the proportion of high-quality energy consumption in Beijing will increase to 95%.'
In Hebei, the construction of Zhangbei Flexible DC Project will realize the Zhangbei New Energy Base, Fengning Energy Storage Power Source and the Beijing Load Center. By then, Beijing will realize 100% clean power source.
Urban energy change is the trend
Not only in Beijing-Tianjin-Hebei but also not only relying on external energy transmission, more cities are exploring the potential and diversity of internal energy supply. In Shanghai, by the end of last year, the largest new energy vehicle photovoltaic supercharging station in China was put into operation, meeting 400 daily Recharging electric vehicles. Shanghai is still building the world's first city for new energy vehicles. In 2017, about 61,000 new energy vehicles were promoted, and the cumulative total reached 166,000, ranking first in the country.
The historic city of Suzhou is also at the forefront of the city’s energy transformation. It is building a world-class city distribution network demonstration city. The walls of the city are tiled and tiled, bridges flow, and garden landscapes are in harmony with modern industry. As the major artery of this city’s energy, Suzhou’s power grid The system will build a world-class city grid during the 13th Five-Year Plan period.
Looking down to Shenzhen, the world’s first bus-powered all-electricity city is under construction. More than 10,000 pure electric buses and more than 10,000 pure electric taxis make up the world’s largest pure electric city public transport system. The first large-scale pumped storage power station in the city was put into production in Shenzhen last year. China Southern Power Grid plans to invest 6.1 billion yuan in Shenzhen to accelerate the establishment of a world-class power grid, promote distribution automation in Shenzhen, optical fiber communications, smart meters and low-voltage power distribution. One 'full coverage', put into operation 1845 distribution network projects, to create a safe, reliable, green, efficient smart grid.
The special economic zone Hainan focuses on the reform of electricity and natural gas systems. It will carry out comprehensive energy reforms, and will accelerate the promotion of new energy vehicles and energy-saving and environmentally friendly vehicles. Hainan Island will gradually ban the sale of fuel vehicles. By the end of the year, Haikou will implement 100% of public transport clean energy vehicles. Full coverage.
Whether it is in Qinghai in the northwest, Gansu, Sichuan in the southwest, Chongqing, or Inner Mongolia in the north, Heilongjiang; Whether it is developing cleaner energy, building a smarter grid, or experimenting with complementary energy sources In the energy system, many cities have written their own chapters on the road to energy change. More and more cities are upgrading their quality under the impetus of new energy systems.
