The use of wind energy by mankind has been used for thousands of years. Initially, it was mainly used to raise water for irrigation, salt water, and wind driven mills. At that time, human beings used the power of the natural world to use wind power and hydraulic power instead of human and animal power to drive the work machinery and increase productivity. As far as humans use wind energy to drive ships, they can be traced back to more distant times.
As an important part of clean energy, the share of wind power generation in the national power generation is gradually increasing.
According to the Prospect Industry Research Institute's "2018-2023 China Wind Power Industry Market Forward-looking and Investment Strategic Planning Analysis Report", China's newly added grid-connected wind power installed capacity was 15.03 GW last year, and the cumulative installed capacity reached 164 GW, accounting for the total installed capacity of power generation. 9.2%; The annual wind power generation capacity is 305.7 billion kWh, accounting for 4.8% of the total power generation, which represents an increase of 0.7% from 2016. In 2017, the national average utilization hours of wind power was 1,948 hours, an increase of 203 hours over the same period of last year.
In January-February, the country’s newly added power generation capacity was 23.56 million kilowatts, an increase of 46% year-on-year. Nearly half of the newly added photovoltaics installed, thermal power, hydropower, a larger decline. In January-February, PV installed 10.87 million kilowatts (10 GW), accounting for 46.1%, an increase of 219.7%; wind power 4.99 million kilowatts (5GW), an increase of 68.6%; thermal power fell 25. 1%; hydropower decreased by 64.6% year-on-year. As of the end of February 2018, China's wind power installations have approached 170 million kilowatts, and photovoltaics have reached 100 million kilowatts, accounting for approximately 9.8% and 6.1% of the total installed capacity. There is still much room for improvement.
The on-grid electricity price of wind power dropped again, and the adjustment rate was larger. According to the Notice on Adjusting the On-grid Price of Onshore Wind Power Benchmarking of Photovoltaic Power issued by the National Development and Reform Commission at the end of 2016, the on-grid tariff of wind power in each resource zone is lowered. The I-zone resource area is directly adjusted from the previous 0.47 yuan/kWh. At the rate of RMB 0.40/kWh, the rate of decline was nearly 15%, and the decline rates of Type II, III, and IV resource areas were 10%, 9.3%, and 5.0% respectively.
For the future development of wind energy in China, industry sources said that wind energy has been highly valued by governments of all countries because of its cleanliness and reproducibility, and it has continuously increased its investment and construction. It has now become the third largest coal-fired power station and hydropower station. Big power supply. It is imperative to effectively solve the problem of power storage and conversion by maintaining a consistent installed capacity and infrastructure. Wind power development plans should be effectively integrated into the power development plan. Only harmonization and unification can make more efficient use of wind power.
