Pursue "wind" and "day", leading the development of China's new energy industry

In 2017, China's photovoltaic, wind power and other new energy sources continued to grow at a rapid rate. While the installed capacity continued to increase, the growth momentum continued to change, and the industrialization technology level gradually increased. The cost of photovoltaic power generation continued to decline, and the problem of abandoned winds and abandoned light improved significantly. China is undergoing a rapid transition from a new energy source to a new energy source -- chasing "wind" to "day". The pace of development of China's new energy industry has long been beyond the reach of the developed countries. In 2017, China's photovoltaic, wind power and other new energy sources continued to grow at a rapid rate. While the installed capacity continued to increase, the growth momentum continued to change, and the industrialization technology level gradually increased. The cost of photovoltaic power generation continued to decline, and the problem of abandoned winds and abandoned light improved significantly. Experts said that China's new energy industry has stepped out of the stage of simply seeking to install the aircraft, and is rapidly transforming from a new energy source to a new energy source.

Installed capacity continues to climb

"In 2017, China's total installed capacity of power generation reached 1.77 billion kilowatts, of which non-fossil energy sources accounted for 38.1% of installed capacity, an increase of 9.6 percentage points over 2012, which is the fastest growing period in history." Baier Baili disclosed that in 2017, China’s installed capacity of renewable energy power generation was about 656 million kilowatts, and the newly installed capacity accounted for about 40% of the global increase. The installed capacity of wind power and solar power generation is steadily ranked first in the world, and has become a leader in the development of non-fossil energy in the world.

It is worth noting that renewable energy has become the main force of new electricity in China, and the growth of new energy such as photovoltaic and wind power is particularly prominent. According to data from the National Energy Administration, in the first three quarters of 2017, the installed capacity of photovoltaics surpassed expectations, and the installed capacity of new photovoltaic power generation reached 43 million kilowatts, an increase of 65.4% year-on-year. As of the end of September 2017, the installed capacity of photovoltaic power generation nationwide has reached 120 million kilowatts, of which, photovoltaic power plants have reached 94.8 million kilowatts and distributed photovoltaics have reached 25.62 million kilowatts.

In terms of wind power, in the first three quarters of 2017, the nation’s newly added wind power grid capacity was 9.7 million kW. By the end of September, the accumulated wind power grid connection capacity reached 157 million kilowatts, and the cumulative capacity increased by 13% year-on-year. In the first nine months of 2017, wind power was generated throughout the country. The amount of 212.8 billion kWh, an increase of 26% year-on-year; the average utilization of 1386 hours, an increase of 135 hours.

With the expansion of scale, the use of new energy continues to increase. In the first three quarters of 2017, the renewable energy generation amounted to 1.17 trillion kWh, which accounted for about 25% of the total output of the above-scale power generation. Wind power, photovoltaic power generation, and biomass power generation increased by 26%, 70%, and 25 respectively year-on-year. %.

In addition, the quality of new energy industry development continues to improve. Wang Bohua, secretary general of the China Photovoltaic Industry Association, said that thanks to the development of the semiconductor industry, photovoltaic production equipment has a relatively high degree of localization in the field of pan-semiconductors. At present, China has basically achieved localization of photovoltaic production equipment. At the same time, for the development of the photovoltaic industry, the domestic policy environment has gradually improved, and photovoltaic applications have gained innovation.

Driven by this, the cost of new energy generation continues to decline. The data shows that in 2017, the cost of wind power and photovoltaic power generation in China dropped by 20% and 60% respectively year-on-year. According to Zhu Ming, Director of the New Energy and Renewable Energy Division of the National Energy Administration, the price of wind power in one type of resource area has dropped from 0.51 yuan per kilowatt-hour to 0.47 yuan, and local conditions have already met the conditions for access to the Internet at a low price after limiting power curtailment.

Abandoned abandoned wind rate decreased year-on-year

The large-scale consumption of new energy is a worldwide problem. Compared with foreign countries, China's resource endowments, energy structure, and market conditions are very different, and the issue of new energy consumption is even more prominent. However, with the introduction of a series of policies to promote the absorption of new energy and the support of large-scale friendly integration of new energy technologies, the problem of new energy consumption has been significantly eased. Nur Baikel said that in 2017, the national abandonment rate and abandonment rate were expected to decline by 6.7 and 3.8 percentage points respectively year-on-year.

“Abandoning the wind and discarding the light is a phased issue that arises in the development of renewable energy, because it involves a lot of energy structure adjustment, energy optimization layout, power dispatching operation, power system reform and marketization, and the implementation of green energy development. Zhu Ming stated that the National Energy Administration will address this issue as one of the important tasks of energy work, and has taken a series of targeted measures with the relevant regional energy authorities and power grid companies. Improved.

Since 2017, the National Energy Administration has continuously optimized the layout of new energy development and construction, and strictly controlled the new construction scale of photovoltaic power generation in areas severely discarded, especially in Xinjiang and Gansu. At the same time, properly shifting the focus of development to the Middle Eastern and Southern regions that do not give up light.

In order to promote new energy consumption, in the implementation of the entire network unified scheduling, the national power grid to break the past sub-provisional standby mode, the entire Northwest unified network to arrange spare, as much as possible to reduce the thermal power, increase the space for new energy consumption. Through cross-regional direct current, when the Central China pumping power station troughs, it purchases northwest wind power to pump water and increase the amount of new energy traded electricity. At the same time, the implementation of new energy in the entire network of mandatory consumption. Before giving priority to the delivery of new energy sources to cross-zone direct-connected thermal power plants, when abandoned winds are abandoned, the auxiliary thermal power will be forced to reduce and give priority to the transmission of new energy.

New kinetic energy continues to form

The reason why China's new energy industry can continue to maintain rapid growth is closely related to the emerging new energy. In the past two years, when the installed capacity of photovoltaic centralized power stations slowed down, distributed photovoltaics suddenly took off and supported the rapid growth of the entire photovoltaic industry. When the growth rate of installed capacity of onshore centralized wind power declined, offshore wind power and decentralized wind power were Become a new focus of the market.

According to Li Chuangjun, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, new energy development is progressing from a resource-intensive area to a load-intensive area. About half of the new wind power installations in the first three quarters of 2017 are located in the eastern and southern regions; The pattern of energy concentration and decentralized development is gradually emerging, with more than one-third of distributed photovoltaic power generation installed in new photovoltaic power generation facilities.

"The rapid growth of distributed photovoltaic installations is a major highlight of the development of the photovoltaic industry. The newly installed capacity of distributed photovoltaics is expected to exceed 10 GW," said Xing Yiteng, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration. Data show that in the first three quarters of 2017, photovoltaic power stations installed 27.7 million kilowatts, an increase of 3% year-on-year; distributed photovoltaic installed capacity was 15.3 million kilowatts, an increase of four times year-on-year.

The "13th Five-Year Plan for Energy Development" shows that by 2020, the scale of solar power generation will reach over 110 million kilowatts, of which distributed photovoltaics will be 60 million kilowatts and photovoltaic power stations will have 45 million kilowatts. The focus of development in the coming years will be on distributed.

In terms of wind power, offshore wind power and decentralized wind power have accelerated development. In September 2017, the first units of the first phase of the offshore wind power project in Xinghua Bay, Fuqing, Fujian Province formally connected to the grid for power generation. This means that starting from the offshore wind power base in Fujian, China’s offshore wind power has entered a new phase of rapid development in the development of concentrated joints.

Sun Qiang, executive director of Three Gorges Group Fujian Energy Investment Co., Ltd., said that China has the natural advantage of developing offshore wind power, with a coastline of 18,000 kilometers and a sea area of ​​more than 3 million square kilometers. The offshore wind energy resources are abundant. According to the preliminary results of the detailed investigation of wind energy resources by the China Meteorological Administration, the installed capacity of wind power is about 200 million kilowatts within the range of 50 meters above sea level within the depth range of 5 to 25 meters in China. Offshore wind power is the future development direction of China's power generation industry.
