my country is the country with the most renewable energy power generation in the world's wind and solar energy。but,In the rapid development of my country's wind power and solar power in recent years,Accompanied by more serious abandonment and light abandonment。Due to the interval of wind and solar resources,Among these renewable energy power generation costs,In addition to the direct cost of the construction cost of the electric field and the cost of connecting the network,It should also include the indirect cost of spare -related related costs,Especially after the large -scale development of renewable energy,It should pay more attention to this part of the cost。In our country,Renewable Energy Power Generation Project access -grid price is higher than the local conventional electricity price, and the network cost is available,Eliminate nationwide through the way to collect electricity prices to electricity users,and the cost of supplementary services such as spare services shall be balanced by provincial power dispatch trading agencies in the province。This asymmetric incentive policy has led to provincial local governments to actively develop renewable energy power generation projects,Lack of incentives in the elimination of renewable energy power。

The cost of renewable energy power generation projects includes both power generation equipment、Land、Infrastructure、Direct cost of transmission network, etc.,It should also include indirect costs related to spare。Related costs related to reserve include fixed costs such as new backup capacity and variable costs such as peak adjustment。such as,Flexibility of thermal power is large investment,A 350,000 kilowatt thermal power plant increases Bet365 lotto review by 20%-30%of the rated capacity peak space,Tens of millions of yuan to invest。,Decreased power will lead to a reduction in power bet365 best casino games generation efficiency of generator sets,Rising cost of power generation,Treatment of peak adjustment costs。
Related costs related to renewable energy power generation and time dislocation of the load curve。Wind power and solar power generation are intermittent、Unstable Questions,Do not have the characteristics of scheduling of traditional units。Wind power and solar power generation forces and system load curves are usually reverse correlated,When the load goes high,Power power generation for renewable energy may begin to lower,Existing time inconsistencies。When the power of wind power or solar power generation has a large fluctuation,Need to dispatch other power plants in the grid to change the level of contribution,Use changes in the power of wind power or solar power generation,Especially when the load is low,The conventional power plant crew has been transferred to a lower force,If the power generation of renewable energy power has increased significantly,So can the conventional units further reduce the power to make space for renewable energy power generation,Determined the ability of the power grid to accept renewable energy power。
Related costs related to renewable energy power generation。In the early stage of the development of wind and solar power generation,The proportion of these renewable energy in the installed capacity is low,The impact on the operation of the power grid is small,Indirect costs tend to 0,At this time,The focus of attention is its direct cost。Due to the existence of the "dry middle school" effect,As the scale of renewable energy power generation is getting larger and larger,The cost of renewable energy power generation equipment tends to decrease。Excellent resources、Low construction cost、Regions with good investment and market conditions,At present, the direct cost of wind power and solar photovoltaic bet365 Play online games power generation can compete with traditional fossil energy。but,With the increase in the proportion of renewable energy power generation machine,The indirect cost tends to rise。
Efforts to solve the problem
Development of renewable energy and electricity projects,It can convert the resource advantage of a region into an economic advantage,Promote local sustainable development。At the end of 2004,my country's cumulative wind power installed capacity is only 740,000 kilowatts。In the 2005 "Renewable Energy Law" passed after passing,Wind power loading machine ushered in explosive growth,Four years in a row,By the end of 2008, the cumulative installed machine reached 12 million kilowatts。"Renewable Energy Law" stipulates that renewable energy and electricity are required for all -in -one acquisition and subsidy costs in the whole society。After the approval right of wind power projects below 50,000 kilowatts is decentralized to the place,"495,000 kilowatt phenomenon" appeared in some places,The purpose is to bypass the approval of the central government。This leads to a certain degree of local wind farm construction and difficulty in griding difficulty。Construction of wind farms for wind farms for certain areas、Disputes and subsidies that have been acquired in full acquisition of wind power issues in a timely manner,The whole country has been revised in 2009 and revised the "Renewable Energy Law",Requires to strengthen the connection between central planning and local planning,It is clear that the full guarantee acquisition of renewable energy power generation and the deployment process of the Ministry of Finance's participation in renewable energy development funds。,my country's renewable energy power generation construction ushered in leapfrog development,However,Blind wind power construction speed。After the approval right of the wind farm project in 2013, the right to be decentralized to the local government,The National Energy Administration established the wind power bet365 live casino games industry monitoring and early warning mechanism,Guiding all provincial wind power development investment。2017 Jilin、Heilongjiang、Gansu、Ningxia、Xinjiang and Inner Mongolia are listed as the Red Early Warning Area (referred to as the "Red Six Provinces")。At the end of 2018,my country's wind power cumulative grid -connected installation machine reaches 180 million kilowatts,Solar power generation installed capacity of 170 million kilowatts,Living in the world's first place。
my country ’s renewable energy resources and power load space dislocation,Determined the necessity of cross -provincial elimination of renewable energy power。my country's wind energy resources areas are mainly concentrated in the northwest region、my country's wind energy resources areas are mainly concentrated in the northwest region,Solar resources areas are mainly concentrated in northwest and North China,and the power load center is mainly located in the eastern coastal area。The asymmetric distribution in the space between this resource and load,It determines that it is difficult to achieve the large -scale development of renewable energy by relying on the province.。such as,Different development of decentralized wind power with key foreign countries,Large -scale centralized development and long -distance high voltage transportation is an important feature of my country's wind power development。Current,my country's "Three North" regions can be renewable energy installations over 170 million kilowatts,It cannot be eliminated by the local area。
Electricity is the basic product,Involved in the face wide。Electricity price directly affects residents' welfare and industrial competitiveness in a region,Political and economic sensitivity。Due to the interval of renewable energy resources,Renewable energy power of removal of provinces,In addition to reducing the power generation in this province,It will also reduce the power bet365 best casino games generation efficiency of this province,Increase the cost -related cost。This part of the cost -related cost can only be under the condition of balanced in the province,It will push the cost of power supply in the province。So,The lack of enthusiasm for the lack of renewable energy power outside the province。2015 Party Central and State Council has further deepened the reform of the power system,Encourage the development of "cross -provincial and cross -zone power bilateral transactions"。but,Wind power、Photovoltaic and other renewable energy power after participating in market -oriented transactions,The price of delivery of electricity across provinces is often very low。
Establish a global mechanism of renewable energy power consumption
For the supply and demand for renewable energy power for renewable energy in my country, the situation that is still mainly based on the balance of the province and local consumption,It is necessary to establish a global mechanism for renewable energy power consumption。Due to the calculation of the cost -related costs, it is facing technical complexity,It is difficult to accurately measure and share it in the whole society like an Internet electricity price。First,Spare service is divided into basic services and paid services,such as,Coal -fired power plants can only get compensation only under the conditions of deep peak adjustment。Next,Spare service is divided into two aspects of fluctuations in the fluctuations and balanced energy power generation of the load。Last,The cost of spare -related costs has a variant in time and space,Both the penetration rate of renewable energy power (the proportion of renewable energy power accounting for load),It is also related to the flexibility of the power system。The cost of spare -the -related costs can only be grasped by the power dispatching agencies of each province,There is information asymmetric。Although the cost of spare -related costs is difficult to share in the whole society,But you can clearly bet365 Play online games clarify the responsibility division of the renewable energy power for renewable energy power at the national level。The division of responsibilities can provide policy support for renewable energy power cross -provincial consumer,Forms a working force for the whole society to promote renewable energy to consumption。
First,All cross -regional power consumption is incorporated into the auxiliary service compensation mechanism in the power area as soon as possible。In 2014, the National Energy Administration once requested the incorporation of cross -provincial and cross -regional electricity capacity into the auxiliary service compensation mechanism in the electrical area,But in specific practice,Only Su, Zhejiang and Shanghai can be implemented in some cross -regional electricity power。External electricity enjoying "privileges" is essentially also easy to enhance the provincial barriers,By undertaking the obligations you should bear,More conducive to expanding the transaction between provinces。
2,Promoting the mechanism for cross -provincial cross -regional sharing and compensation auxiliary services。Expand the Northeast China -sharing and compensation auxiliary service mechanism to cross -regional,Optimized allocation of assistive service resources in a larger range。
third,Lay the price of the price of renewable energy green power certificate。The current "green certificate" transaction is mainly to reduce the financial pressure of renewable energy power generation subsidies,No compensation contains auxiliary services,Disadvantages to the province for transfer。
In short,Promoting the development of the renewable energy industry is an important measure to promote the adjustment of my country's energy structure and consumer side cleaning low carbon transformation,Realization of full consumption is a key guarantee for the high -quality development of the renewable energy industry。
