The report of the 19th National Congress of the Communist Party of China put forward "promoting the revolution of energy production and consumption and building a clean, low-carbon, safe and efficient energy system." The State Grid Corporation of China earnestly implemented the spirit of the 19th National Congress of the Communist Party of China and established a new "1 June" strategy system that meets the requirements of the new era, conforms to the trend of energy production and consumption revolution, and conforms to the laws governing the development of modern enterprises.
State Grid Fujian Electric Power Co., Ltd. fully implements the new era development strategy of the State Grid Corporation of China, and proposes to build a “Fujian Model†in building a world-class energy Internet company with excellent competitiveness; in serving the new Fujian construction and “catch-up†strategy We will create a new era of "national network model", vigorously implement the "two-wheel drive" to strengthen reform and innovation, and stimulate endogenous power to promote the high-quality development of enterprises and power grids.
Developing clean energy is an important goal of building a world-class energy Internet. State Grid Fujian Electric Power seized the opportunity of the first national ecological civilization pilot zone to land in Fujian, vigorously implemented the re-electrification strategy, promoted energy supply side clean replacement and consumption side energy replacement, and strived to be a pioneer in energy transformation and development, and achieved clean energy for many years. The amount of consumption will help accelerate the transformation of economic and social development to “greeningâ€, making the sky bluer, the mountains greener, the water clearer and the environment more beautiful. At present, the number of days with good air quality in the construction area of ​​Fu Construction is among the highest in the country, and “Fresh and Fujian†has become a beautiful business card.
"Internal transfer" clean energy full consumption
Spreading the layout of power supply in Fujian, all kinds of power plants are scattered. Fujian Power Grid is one of the few provincial-level power grids with complete water, fire, gas, nuclear, wind and photovoltaic power sources. The proportion of clean energy installed capacity is 54.5%, nuclear power The installed capacity is second only to Hainan and ranks second in the country. Fujian has successfully realized a splendid turn from a small province of natural energy reserves to a clean energy province.
On May 4th, Fuqing City Power Supply Company was stepping up the construction of the 220kV line of the Huayu Reef Wind Farm in Fuqing, and the power supply company of Fuqing City was stepping up the coordination of the construction and construction of the project. The plan is completed and put into operation at the same time as the wind farm.
Clean energy construction must be equipped with transmission channels of corresponding scale to ensure smooth access to the power grid. In order to ensure the matching of power grid construction and clean energy construction, State Grid Fujian Power actively communicated with wind power and photovoltaic project builders, and planned to build power grids ahead of schedule. In the past five years, State Grid Fujian Power has completed the commissioning of a grid of supporting power generation projects of 35 kV and above, with a transmission line of 1,200 km and 12 substations, ensuring that clean energy power generation projects are connected to the grid in time.
Clean energy, especially new energy, is connected to the grid on a large scale, and its intermittent and volatility poses a challenge to power consumption.
How to make full use of clean energy is the direction that State Grid Fujian Power has been working hard, and it is also the energy development issue that all levels of government in Fujian Province attach importance to.
According to the characteristics of Fujian's clean energy development, State Grid Fujian Power Research and Development Smart Grid Clean Energy Monitoring and Dispatching System, comprehensively mastering 259 water level stations and 638 rainfall stations in Liujiang and Liangxi, and 82 wind power and photovoltaic power stations in the province. The single-machine power generation information, wind tower data, solar radiation, and more than 11600 distributed photovoltaic power stations are monitored in real time. The wind power and photovoltaic power generation capacity predictions for the next 7 days will be carried out for the first time in the country, and a variety of power supply joint optimization scheduling models will be constructed. Through the hydropower station and LNG gas power station with strong regulation ability, it can complement the wind power and photovoltaic power generation to maximize the power generation capacity of clean energy and realize the full consumption of clean energy. For many years, the Fujian power grid has no water, no wind, Abandon the light phenomenon.
At the same time, State Grid Fujian Power actively explored and established a sound compensation mechanism for auxiliary services, and used market means to enhance the enthusiasm of thermal power units to participate in peak shaving. The company was the first batch of auxiliary service and spot market pilot construction units, and the auxiliary service market was commissioned in September 2017.
At present, the total transaction volume of the market transaction costs, the compensation and the proportion of the various types of power supply are basically in line with expectations, which truly reflects the contribution of auxiliary services of various types of power sources, stimulating the enthusiasm of power plant peak shaving, and promoting the active participation of thermal power enterprises from passive emission. The peaking shift has expanded the clean energy consumption space.
In addition, in the past two years, due to the rapid growth of nuclear power installed capacity and the slowdown in the growth of demand for electricity in Fujian, Fujian has a surplus of electricity and limited space for clean energy development.
“In order to improve the utilization rate of clean energy, we are strengthening the power grid peaking capacity and promoting the clean energy consumption. At the same time, we are also trying to promote clean energy cross-regional delivery, so that clean energy can be deployed in a wider range.†State Grid Fujian Power related person in charge.
This year, Fujian Power Trading Center relied on the advantages of 1000 kV Zhebei-Fuzhou UHV inter-provincial power grid to promote the establishment of a 1000 kV Zhebei-Fuzhou UHV annual trading mechanism to further enhance the frequency of Fujian nuclear power transmission transactions. At the same time, the center relies on the national unified power market trading platform, actively communicates and strives for Fujian's surplus power to be sent across the province, promotes the relevant provinces and cities in East China to compensate for the power shortage caused by coal control, and actively expands the clean energy outside the province.
In the first quarter of this year, Fujian's cross-provincial transaction volume reached 10.082 billion kWh, and the transaction volume reached 3.7 times that of the same period of last year. The annual transaction scale exceeded the 10 billion mark for the first time, the highest in history. Among them, nuclear power delivered by the company reached 6.414 billion kWh, doubling year-on-year, further promoting the clean energy consumption in Fujian.
Relying on large power grids and large markets, Fujian Clean Energy achieves a wider range of optimal configurations.
In 2017, Fujian's clean energy power generation accounted for 52%, and Fujian's wind power generation hours ranked first in the country for five consecutive years.
Government and enterprise
“Sea, land and air†promotes electric energy replacement
The replacement of electric energy is the main content of re-electrification and an important way to promote the revolution of energy consumption. State Grid Fujian Power is guided by six major areas, namely port shore power, airport power, electric vehicles, electric boilers (electric kiln), agricultural electrification, and household electrification. The “sea, land and air†all-round push for electric energy replacement.
Blue sky and blue sky, egrets fly. On the morning of April 19, after the return of the Xiamen Jiageng scientific research ship to Hong Kong, it was firmly docked at the No. 13 berth of Xiamen Yuanhai Container Terminal. During this period, it shut down the fuel generator on the ship and switched to the use of high-voltage shore power supply.
Xiamen Yuanhai Container Terminal is located in the Xiamen Area of ​​Fujian Pilot Free Trade Zone. The scene is quiet and orderly, and there is no gasoline smell in the past. This is the country's first zero-emission, all-electric, fully automatic modern terminal. In December 2016, a 3 MW ship high-voltage shore power system under construction by Xiamen Power Supply Company was officially put into operation, which could provide normal power supply for large container ships of 100,000 tons and below.
The blue sky and blue sky, the grid people use green power, clean power to protect.
The implementation of electric energy substitution in energy consumption terminals has become an important starting point for energy saving and emission reduction in Xiamen, and is being actively promoted. According to the “Implementation Plan for Electric Energy Substitution in Xiamen Cityâ€, by 2020, Xiamen will promote the proportion of energy consumption in terminal energy consumption to reach 29%. It will build ship shore power demonstration projects in container terminals and cruise port home ports, and promote various types of port terminals. Full implementation of "oil to electricity".
At the same time, the re-electrification strategy has been fully recognized by the local government, and relevant policies have been issued to fully support the implementation of electric energy replacement projects. On October 22, 2017, Xiamen Municipality promulgated the “Interim Measures for the Administration of Coastal Powers for Ports of Vessels in Xiamenâ€. In accordance with relevant regulations, the port power equipment and ship power facilities will be reconstructed in 2017 and 2018. Get 70% and 60% of the construction incentives in addition to the central and provincial subsidies (or incentives) for the remaining portion of the investment. Port-based power supply activities can receive port power supply service awards of 1.05 yuan to 0.80 yuan per kWh of electricity, and policy support is at the leading level nationwide.
Together with Xiamen City, it is the Pingtan Comprehensive Experimental Zone of the Fujian Pilot Free Trade Zone. The nation's first low-carbon, high-efficiency and ecological whole electrified island construction is also in full swing.
"Our goal is to achieve full power replacement in the public service areas and tourism service facilities throughout the island by 2020, and the utilization rate of clean electricity in the areas of eating, living, traveling, and music is 95%." The relevant person in charge of Pingtan Power Supply Company said.
In fact, the construction of electrified islands is also a beautiful vision of the local government.
In May 2017, the Pingtan Comprehensive Experimental Zone introduced an energy alternative implementation plan, and proposed a joint establishment of government and enterprises to clarify the government's electrification energy consumption ratio and subsidy policy in the construction plan.
“Incorporate the application of electrification into the overall planning of the scenic area renovation project, publicize and promote new technologies for replacing electric energy, change energy consumption habits, and advocate the concept of green energy.†The relevant person in charge of the Economic Development Bureau of Pingtan Comprehensive Experimental Zone said that they are actively cooperating The power supply enterprises vigorously promoted the gas conversion of hotels, hot pot restaurants and rotisseries, and increased the proportion of electric energy in stoves, and built a "green kitchen."
With the introduction of electric energy replacement projects in various fields, in 2017, Fujian achieved an alternative power of 7.1 billion kWh, a year-on-year increase of 65%. In 2018, the replacement power is expected to reach 9 billion kWh.
