Information
Recently, according to Wu Jiandong, vice chairman of the China Intelligent Engineering Research Association, at the Renewable Energy Power Generation and Grid Grid Forum, the power law that is being revised will include the relevant content of new energy grid-connected power generation, which will provide laws for new energy grid-connected power generation surroundings. Since my country's current "Electric Power Law of the People's Republic of China" was implemented on April 1, 1996, the development environment of the electric power industry has undergone great changes, and the current electric power law has obviously lagged behind the development needs of the electric power industry in some aspects. For example, the problems related to grid-connected power generation of new energy. In recent years, especially since the 11th Five-Year Plan, the development of new energy has been very rapid, but the construction of supporting laws and policies has been relatively lagging. Many obstacles to the "bottleneck". Creating a legal environment suitable for the development of new energy may provide a strong guarantee for the large-scale and rapid development of new energy, and it is expected to solve the old difficult problem of the power grid.
The development of new energy is restricted by the construction of the power grid
According to Sun Yucai, Secretary of the Party Leadership Group and Executive Vice Chairman of the my country Electricity Council, in terms of the power structure of China last year, the proportion of clean energy such as hydropower, nuclear power, wind power, and solar power reached 27.5%, an increase of 0.9% over the previous year. The grid-connected capacity of wind power and solar power has increased extremely rapidly. Last year, the grid-connected capacity of wind power was 45.05 million kilowatts, and the grid-connected capacity of solar power reached 2.14 million kilowatts, an increase of 52% and 723% respectively over the previous year. In terms of power grids, the ability to absorb wind and solar power generation and the ability to safely dispatch has not been improved accordingly, which has caused the contradiction that many new energy sources "cannot be absorbed".
According to relevant data, my country’s wind power curtailment last year exceeded 1.1 billion kWh, accounting for 12% of the total wind power generation. In 2008, the wind power curtailment was only 296 million kWh. This shows that the large-scale centralized development of wind power is increasing. The more severely it is affected by the construction of power grid transmission channels. Some experts pointed out that large-scale "bundled" transmission and on-site balanced consumption did not effectively solve the problem of grid connection of wind power bases, resulting in a disguised waste of resources. This is in contrast to the lagging of grid planning and construction and lack of supporting facilities. Adapted laws, policies and standards are closely related.
It is understood that the "Renewable Energy Law" stipulates that grid companies shall, in accordance with the planning and construction of renewable energy development and utilization, fully purchase the on-grid power of renewable energy grid-connected power generation projects that meet the grid-connected technical standards within their grid coverage. It is proposed that grid companies should improve grid operation management and increase the ability to absorb renewable energy power. In terms of wind power grid connection, the national standard GB/T19963-2011 "Technical Regulations for Wind Farm Access to Power Systems" was promulgated at the end of last year and will be implemented on June 1 this year. It is in line with the industry standard "Large Wind Farms" approved by the National Energy Administration. Grid-connected design technical specifications jointly stipulate the relevant technical requirements for grid-connected wind farms. Analysis believes that there have been many wind abandonments in Inner Mongolia, Jilin and other regions because the relationship between wind farms and power grids is not regulated by relevant industry standards and national standards. However, whether renewable energy can be fully integrated into the grid within the “grid coverage area” also depends on the pace of construction of the grid transmission channel.
The formulation of regulations and standards should be "appropriately advanced"
According to relevant data from the my country Electricity Council, China’s wind power installed capacity is planned to be 100 million kilowatts and 180 million kilowatts in 2015 and 2020, respectively, and the planned solar power installed capacity is 5 million kilowatts in 2015 and 25 million kilowatts in 2020. At present, the above data may still be conservative. Due to the incentives of the national solar photovoltaic power generation tariff policy, the development speed of solar photovoltaic power generation in my country is likely to accelerate further, especially in the BIPV field, which will exceed expectations. On the other hand, the development thinking of wind power has also changed from large-scale centralized development to large, medium and small, decentralized and centralized, land and sea joint development. Under the guidance of appropriate policies, small and medium-sized wind farms will be connected to the grid and consumed locally. It is also expected to gain extensive development.
As the national subsidy policy has been introduced, the solar photovoltaic market has the market momentum for development, but there is still a lack of corresponding technical standards in terms of solar power grid connection. If the grid "bottleneck" is not resolved, solar grid-connected power generation may repeat the same mistakes as wind power grid-connected power. It is understood that more than 40 key photovoltaic grid-connected technical standards have been compiled by China Electric Power Union, China Electric Power Research Institute, State Grid Electric Power Research Institute and other units, such as "Design Specification for Photovoltaic Power Station Access Power System", "Photovoltaic The "Code for Design of Power Generation Access to the Distribution Network" and "Technical Code for Reactive Power Compensation of Photovoltaic Power Stations" have basically formed drafts and drafts for soliciting opinions. According to the plan, the preparation of a number of photovoltaic standards will be completed in the first half of this year, but at least hundreds of standards are required to build a complete photovoltaic grid-connected power generation standard system. These standards take into account the needs of power users, power stations, and photovoltaic roofs.
"Building photovoltaic specifications are already being drafted, such as rooftop photovoltaics." Xu Zheng, director of the Institute of Optoelectronics Technology, Beijing Jiaotong University, said that solar photovoltaics will be very useful in the field of construction, because the user-side grid connection does not require long-distance transmission and reduces The impact on the power grid. The key is how to regulate the relationship with the power grid and achieve both constraints and incentives, so as to form consensus on multiple levels and truly promote the development of new energy.
"The revised Electricity Law involves new energy grid-connected power generation. This will regulate and coordinate the relationship between new energy grid-connected power generation and the power grid from the legal level, and it is likely to form constraints on grid companies. However, new energy power generation For the large-scale development of power generation, power grids and users need to find a better balance, such development can be sustainable." An industry expert told a reporter from China Energy News.
