In the first three quarters of this year, the abandonment of abandoned water, abandonment of wind, and abandonment of the country has improved, and the overall level of consumption of renewable energy has gradually increased. However, in the winter, wind power and photovoltaic power generation are most difficult to use, and local areas are under pressure to abandon the wind and abandon the light. At the same time, due to the flooding at the end of the flood season and extreme weather, hydropower in Sichuan, Yunnan, and Guangxi are still under pressure. It is still faced with major challenges to achieve effective relief of abandoned water, abandoned wind, and abandoned light.
Increase local efforts
Since the beginning of this year, local and power grid companies have stepped up efforts to take various measures to expand the consumption of renewable energy and have achieved certain results. According to the data released by the National Energy Administration recently, in the first three quarters of this year, the nation’s water abandonment capacity was reduced by 3.5 billion kwh, the water and power utilization rate of hydropower in the southwest increased by approximately 2 percentage points year-on-year, and the electricity generation from abandoned winds decreased by 10.3 billion kwh. The rate dropped by 6.7 percentage points year-on-year; the amount of abandoned photovoltaics increased by 1.4 billion kwh, and the rate of abandoned light dropped by 4 percentage points year-on-year.
However, to achieve a "double drop" in renewable energy abandonment and abandonment rates, energy management departments at all levels and power grid companies still need to take effective measures to promote.
In increasing the local consumption of renewable energy, the National Energy Administration requires Xinjiang, Gansu, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang, and Hebei to work together with clean heating in the northern region to expand the scale of wind power and clean heating as soon as possible. Enterprises and electric heating companies and various types of electric heating users conduct electricity market transactions to achieve wind power heating in line with the direction of clean low-carbon development. The relevant provincial energy management departments should guide local governments in organizing wind power and electric heating companies, and establish wind power heating cooperation mechanisms under the support of grid companies and power trading organization platforms. Xinjiang, Gansu, Inner Mongolia, and other power-restricted regions must supervise their own power plant enterprises to participate in system peaking operations, consume renewable energy, and pass legally compliant direct electricity exchange or replacement power generation to expand the company-owned power plants to absorb renewable energy. Electricity. Sichuan, Yunnan, and Guangxi must promote local electric energy substitution through various means to enhance their ability to absorb renewable energy.
Expand cross-regional transactions
In the area of ​​expanding the export of renewable energy power and inter-provincial trans-regional transactions, the National Energy Administration emphasized that all regional power grids should strengthen inter-provincial inter-economic and inter-provincial reserve sharing, and uniformly call up peak-sharing resources in the region to collaboratively absorb renewable resources. Energy power. Power grid companies must tap the transmission capacity of the trans-provincial trans-regional transmission corridors of Hami-Zhengzhou, Ningxia-Zhejiang, Jiuquan-Hunan, etc., and give priority to the transmission of renewable energy power. The relevant energy regulatory agencies shall conduct annual monitoring and evaluation of the proportion of renewable energy in the cross-provincial cross-regional power transmission channels. State Grid Corporation of China, China Southern Power Grid Corporation, Inner Mongolia Electric Power Company, etc. shall cooperate with power trading organizations to expand cross-provincial cross-regional power spot transactions to absorb renewable energy power. The eastern and central local governments and power grid enterprises that consume renewable energy power should combine the reduction of coal consumption in this region with the input of renewable energy sources outside the consumption area, and take the initiative to promote regional governments with inter-provincial cross-regional power transmission channels. Connected with power grid companies, priority will be given to the electricity market space vacated by the region to expand the use of renewable energy.
In addition, it is necessary to establish a linkage mechanism for renewable energy power consumption and new construction projects. All localities must take effective measures to increase the intensity of renewable energy sources in winter and strive to achieve a “double drop†in wind power, photovoltaic power generation, and abandonment rates. Areas with red warnings should greatly reduce wind power and photovoltaic power generation abandonment rates and try to withdraw from the red limit as soon as possible; regions with early warning results should ensure that wind power and photovoltaic power generation abandonment rates do not rise; and speed up the establishment of hydropower investments to eliminate early-warning mechanisms. . In areas where the rate of wind curtailment and the rate of abandoned light exceed 5% this year, as compared with the previous year, the rate of abandonment of abandoned winds and the rate of abandonment of light have increased significantly. In 2018, the annual increase in the scale of new wind power and photovoltaic power generation in the region will be reduced. , and take measures to stop construction delays.
