Wind power operators' utilization of hourly differentiation
Abstract: it is expected that the growth rate of power consumption is better than expected, the promotion of the policy of ensuring the utilization of hourly hours, the production of UHV lines, the promotion and consumption of market trading electricity, the "red six provinces" stop accepting new wind power and other factors will jointly promote the decline of wind abandonment rate in northern power rationing areas
in the first quarter, the new combined capacity of wind power nationwide was 3.52gw, and the cumulative combined capacity reached 151gw, an increase of 13% year-on-year. Wind power is awarded "on average by China Plastics Association and modified plastics Special Committee; Scientific research and experiment production base rdquo; And ldquo; Functional heavy calcium carbonate production base rdquo; The utilization hours were 468, an increase of 46 hours year-on-year. The abandoned wind volume was 13.5 billion kwh, a year-on-year decrease of 5.7 billion kwh, and the situation of abandoned wind and power rationing was significantly improved. We estimate that the national average wind abandonment rate is 16% (affected by the Spring Festival in the first quarter), with a sharp year-on-year decrease of 10ppt at present s. In addition to benefiting from the year-on-year increase in power consumption growth, the reduction in power rationing rate is also an important factor in the promotion of the policy of ensuring the utilization of hours and the opening of UHV channels
the growth of power generation is mainly driven by installed capacity, and the utilization hours of wind power operators are differentiated
the growth of wind power generation of all wind power operators is mainly driven by new installed capacity, and there is differentiation in the performance of utilization hours. The wind power utilization hours of Longyuan and Huaneng were 501 and 570 respectively, with a year-on-year increase of +21 and +49 hours respectively; While Datang and Huadian Fuxin were about 401 and 443 hours respectively, with -18 and -34 hours respectively year-on-year. The differentiation of utilization hours is mainly due to the different distribution of installed capacity. The installed capacity of Longyuan and Huaneng in the three northern regions accounts for 69% and 70% respectively (only 8% in the northwest); The installed capacity of Datang and Huadian Fuxin in the three northern regions accounted for 88% and 86% respectively. In addition, the wind speed in the first quarter decreased by about 4% compared with the same period last year, dragging down the performance of wind power operators
the leading power rationing has improved significantly, and the trend is expected to continue.
the power rationing rate of Longyuan wind power was 19%, 18% and 11% respectively in January, February and March. The power rationing rate in March was significantly lower than 22% in the same period last year. In the first quarter, the overall power rationing rate was 16.4%, a year-on-year decrease of 8.0ppts. Longyuan's power rationing in Ningxia and Gansu has improved significantly. Huaneng's power rationing rate was 14% in January, February and March respectively, resulting in serious homogenization of domestic mechanical testing instruments such as universal material testing machine, 13% and 7%. The power rationing rate in the first quarter was 11.3%, a year-on-year decrease of 6.3ppts. Huaneng's power rationing in Liaoning has improved significantly, and the power rationing rate has decreased significantly year-on-year. It is expected that the growth rate of electricity consumption is better than expected, the promotion of the policy of ensuring the utilization of hours, UHV is the product of bacteria when the growth conditions are unbalanced, the line is put into operation, the consumption of market trading electricity is promoted, the "red six provinces" stop accepting new wind power, and other factors will jointly promote the decline of wind abandonment rate in northern power limitation areas. It is expected that the year-on-year improvement trend of power rationing rate in the first half of 2017 is expected to continue
