In the next ten years, an average annual increase of 12 million kilowatts of installed capacity will be appropriate. ” At the recent development of the new energy industry base and CEO of the multinational corporation Zhang Bei Forum, China’s renewable energy society The committee’s vice chairman Shi Pengfei said.

In April this year, China's offshore wind power concession bidding project was launched. The industry is widespread concern at onshore wind power equipment manufacturing "excess capacity" phenomenon still persists background, offshore wind power project will start or wind power equipment industry has brought another round of investment boom.

Zhou Fengqi, former director of the Energy Research Institute of the National Development and Reform Commission, emphasized that offshore wind energy technology needs further development. Although the quality of offshore wind energy onshore wind may be better than 50%, but the current building offshore wind investment costs may reach 2 times the land is expected to cost in 2050 will decline by 38%. According to the analysis of the International Energy Agency, offshore wind power generation equipment has many differences in terms of performance, safety and stability due to ocean currents, geology and corrosion, but Zhou Fengqi bluntly stated: “The domestic offshore wind power equipment is just land Upper wind turbine ' oceanization ' . "

Zhou Yuanbing, deputy chief engineer of Guodian Energy Research Institute, said that the current difficulties in grid connection of wind power have not yet been solved. This is due to the lack of a unified plan for wind power development. Wind power development planning is not compatible with power grid planning; there is overall lag in power grid construction. The phenomenon of power supply construction, especially the " Three North " and other wind power development areas are at the end of the power grid, the power grid structure is relatively weak, and the cross-regional power grid interconnection scale is small, which restricts the large-scale distribution and absorption of wind power.

“ On the other hand, grid connection is not a problem set by the grid companies and grid companies. It is not as simple as it appears on the surface, but it is due to the difficulties and challenges arising from factors such as the level of technology, development speed, and the constraints of existing objective conditions. . "he said.

Zhou Fengqi believes that since offshore wind power equipment manufacturing technology is not mature at present, if it is too late to make enough technical preparations, it must start large-scale promotion, and it will be difficult to solve problems after they arise. Therefore, to handle the " fast " and " good " issues, we must make full technical preparations and should be the focus of our first concern.
