The Jiangsu Provincial Development and Reform Commission recently issued the “Special Plan for Electric Power Development in the 13th Five-Year Plan” (hereinafter referred to as “Planning”), and pointed out that by 2020, the proportion of clean energy power generation installed capacity will increase to about 35%, and non-fossil energy power generation will account for The ratio increased to about 20%.

　　Specific to the development direction of wind power in the next five years, the “Planning” pointed out that during the “Thirteenth Five-Year Plan” period, we will adhere to the principle of both sea and land-based and sea-based principles in accordance with the development of coastal large-scale development and inland distributed applications. With offshore wind power development in Lianyungang, Yancheng and Nantong, by 2020, wind power capacity in the province will reach 10 million kilowatts.

　　New energy generation scale leads the country

　　In the past 2016, Jiangsu's new energy industry has achieved a lot.

　　The reporter recently learned that as of the end of November last year, the province had added 1.04 million kilowatts of wind power, totaling 5.38 million kilowatts, of which 1.04 million kilowatts of offshore wind power, and continued to maintain the number one nationwide.

　　At present, new energy projects are being rolled out across Jiangsu. Taking Rudong as an example, as of the beginning of January this year, the installed capacity of Rudong's grid-connected network reached 1.55 million kW, of which the accumulated installed capacity of offshore wind power was 750,000 kW, and the nation’s first offshore wind farm that meets the “Double Ten” requirement was built. Asia's largest offshore wind power base.

　　It is worth noting that the East China Sea Wind Power Industrial Base has recently been approved as a national torch special industrial base. It is reported that the National Torch Characteristic Industrial Base has been identified and managed by the Ministry of Science and Technology. It aims to strengthen the cooperation between the Ministry of Science and Technology and local governments, and further give play to the role of the Torch Program in guiding the development of high-tech industries. The approval of the National Torch Characteristic Industrial Base will help speed up the adjustment of the industrial structure and drive the transformation and upgrading of the related industries such as East and even Jiangsu and the rapid economic growth.

　　Rudong is not alone. In recent years, Yancheng has consistently adhered to its advantages in green development and actively promoted new energy power generation demonstration projects such as “Fish Fishing”, “Wind Car” and “Wind Power Water” to create a national-level new energy industry base. The results achieved are also remarkable. The reporter recently learned from the local power supply company that, as of the end of last year, the installed capacity of new energy in Yancheng was 4,213,000 kilowatts, an increase of 42.19% year-on-year, accounting for 33.34% of the province's new energy installed capacity; the city's new energy power generation was 6.702 billion kwh, year-on-year The growth rate was 44.5%, and the power generation accounted for 30.47% of the province's new energy generation. The new energy generation has reached 27.93% of the total electricity consumption in the society.

　　In fact, the above areas are just a microcosm of the rapid development of wind power in Jiangsu. Industry experts pointed out that from the “13th Five-Year Plan for Wind Power Development” issued by the National Energy Administration earlier, the scale of wind power development in China will shift to the eastern and southern regions in the next five years.

　　Among them, the development goal of onshore wind power in Jiangsu Province in the next five years is as high as 6.5 million kilowatts, ranking first in East China and second in the country; the scale of offshore wind power starts will also reach 4.5 million kilowatts, ranking first in the nation. All signs have shown that wind power in Jiangsu accelerated its imperial wind during the “13th Five-Year Plan” period.

　　Fully promote 18 offshore wind power projects

　　The achievements made by Jiangsu New Energy have been gratifying, but it is still faced with various problems such as the gradual slowdown in the growth of power demand, the tightening of environmental protection constraints, and the increasing difficulties in power grid operation.

　　According to the national and provincial government's relevant planning policies, the proportion of non-fossil energy in primary energy consumption will reach about 11% by 2020; non-water renewable energy will account for 7% of total electricity consumption in society, and this goal must be fulfilled. At present, the task is still arduous.

　　It is precisely for this reason that the "Notice" will clearly adhere to the principles of optimizing the structure and optimizing the layout, developing the principle of centralized and promoting distributed coordination, and striving to increase the proportion of renewable energy generated by wind power and promote clean, efficient and low carbon. High-quality energy has gradually become the main contributor to incremental energy. We will continue to implement a safeguarded acquisition system to ensure that wind power, photovoltaic power generation, and other renewable energy production will be fully consumed. By 2020, the province's coal-fired installed capacity will account for about 63% of the province's installed capacity, and the proportion of clean energy power generation capacity will increase to about 35%, and the proportion of non-fossil energy power generation capacity will increase to about 20%.

　　In terms of wind power development, the "Notice" proposed that by 2020, the province's wind power capacity will reach 10 million kilowatts. In line with the idea of ??large-scale coastal development and inland distributed applications, the principle of both maritime and land-based and sea-based shall be adhered to. It actively promoted offshore wind power development in Lianyungang, Yancheng, and Nantong; and fully promoted the preliminary work and construction progress of the 18 projects identified in the “National Offshore Wind Power Development and Construction Plan (2014~2016)”. In line with local conditions, it will promote the coordinated development of wind power along the coast and inland winds with low wind speed, and promote the development of inland low wind speed wind power as soon as possible. Organize and implement decentralized wind energy application demonstrations to promote decentralized wind power construction with access to low distribution grids.

　　Full acceptance of new energy

　　In the new energy project province, while fully blooming, it is also crucial to actively use ventilation and photovoltaic transmission channels to ensure the full consumption of new energy. From the current point of view, Jiangsu's new energy development also faces many challenges during the “13th Five-Year Plan” period.

　　"Notice" pointed out that during the "Thirteenth Five-Year Plan" period, the province will accept multiple high-capacity, long-distance UHV AC and DC calls, and the difficulty of power grid operation control will further increase. The backbone of power grids has become increasingly tight, and the difficulty in controlling system short-circuit currents has continued to increase. Wind power, photovoltaic power generation and other large access, output volatility and intermittent increase, power generation side control more difficult. With the rapid development of electric vehicles and other electrical energy replacement terminals, the randomness of the demand side gradually increases, and the difficulty of real-time balancing of the power system further increases.

　　Affected by factors such as the seasonal and time-inconsistent nature of the gas grid and the grid, the advantage of the peaking of the gas turbine cannot be fully realized.

　　In view of the above, the "Notice" will clearly use the regional energy development plan in an orderly manner to make use of calls from outside the region to speed up the construction of Ximeng-Taizhou, Jinbei-Nanjing UHV DC projects, according to the National Energy Administration "on the further regulation of coal-fired power." The "planning and construction notice" requires that the sending end provinces control the construction of supporting power supply at the right time. The East China UHV 1000 kV AC ring network and the 10 500 kV provincial links were fully utilized to optimize the dispatching operation of power grids under large-scale out-of-area calls and enhance inter-provincial mutual supply. By 2020, the scale of calls from outside the province will reach around 33 million kilowatts. On this basis, we will adhere to the "safety first, clean priority," the idea of ??different treatment of different types of new calls outside the region, the orderly use of hydropower outside the region, and strictly control the region outside the coal. We will actively use western hydropower and renewable energy sources such as Inner Mongolia and Shanxi to expand the use of renewable electricity in Xinjiang and Qinghai.

　　At the same time, the "Notice" also clearly will continue to promote and improve the 500 kV main grid, optimize the 220 kV grid and accelerate the construction of the distribution network. In order to fully accept clean energy, the province will promote new energy generation power forecasting and dispatching operation control technologies, promote the coordinated optimization and operation of distributed energy, energy storage systems and power grids, enhance service and technical support, and stabilize the volatility of new energy sources. Promote grid-connected devices with plug-and-play and friendly grid-connected features to meet the wide-access requirements of new energy sources and distributed power sources. Further improve the flexibility of network power flow control and control, and improve the ability of the power grid to accept new energy, distributed power, and diversified loads. Encourage the deployment of a certain proportion of energy storage systems in centralized wind farms and photovoltaic power plants, improve the operation and management system of distributed power in the wide area, and improve the distributed power dispatching and operation management model, so as to achieve continuous and full consumption of renewable energy such as wind power and photovoltaic power.
