Question 1: What is the meaning of abandoned light in photovoltaic power generation? The so-called abandoned light means that the power generated by the photovoltaic power station is greater than the maximum transmission power of the power system + the load consumption power.
Solar abandonment rate = power generation of the photovoltaic power station - (maximum transmission power of the power system + load absorption power) / power generation of the photovoltaic power station
Question 2: What is the abandonment of light and wind? What does it mean to give up the use of solar and wind energy?
Question 3: The problem of abandoning wind, abandoning water and abandoning light in the energy field refers to being forced to give up wind, water and light energy due to some reasons, stop Corresponding generating units or reduce their power generation.
Energy is the substance that provides energy conversion to nature (mineral energy, nuclear physics energy, atmospheric circulation energy, geographical energy). Energy is the material basis of human activities. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technology. In today's world, energy development, energy and environment are issues of common concern to the whole world and all mankind.
Question 4: At present, the state stipulates that the rate of wind and light abandonment should be controlled within the recovery rate standard of underground coal mining areas: coal seam thickness assessment index ≤ 1.3m ≥ 85% 1.3-3.5m ≥ 80% ≥ 3.5 m ≥ 75% recovery rate standard for open-pit coal mine mining areas: coal seam thickness assessment index ≤ 1.3m ≥ 70% 1.3-3.5m ≥ 80% 3.5-6.0m ≥ 85% ≥ 6.0m ≥ 95%
Question Five: Is energy storage the most realistic option to solve the problem of wind and solar abandonment?
Question six: Why are wind turbines and solar photovoltaic power stations shut down? Now many places are abandoning wind and solar power.
Because both wind power generation and photovoltaic power generation are time-sensitive and cannot generate stable power. Can only be used as an auxiliary.
Large-scale construction makes it impossible for many areas to consume so much electricity, and the cost of high-voltage transmission is too high.
So now there will be restrictions according to local planning
Question 7: Is the photovoltaic electricity price reduction good or bad for the photovoltaic industry? What is the impact of lowering the benchmark electricity price of onshore wind power and photovoltaic power generation on the photovoltaic companies? Unavoidable. The "Energy Development Strategic Action Plan (2014-2020)" issued by our country has clearly stated that by 2020, the price of wind power generation will be equal to that of coal power, and that the price of photovoltaic power generation will be equal to that of grid sales. If electricity prices are lowered year by year, action will definitely be taken.
The uncertainty of income may reduce the enthusiasm of such enterprises to invest in renewable energy power generation. At this time, a situation of "reverse substitution" of traditional energy with renewable energy may occur. The effect is not conducive to the adjustment of my country's energy consumption structure, improvement of energy utilization efficiency and environmental pollution control. “Price adjustment will narrow the electricity price gap between traditional energy and renewable energy, but the positive benefits this adjustment brings to renewable energy power generation are long-term and slow.
Prerequisites for electricity price reduction It is to ensure the basic rate of return of power generation projects, otherwise it will only lead to a reduction in investment in renewable energy power generation projects. It is to ensure the use time of power stations, which means that the problem of wind and light abandonment must be solved on time and on schedule. It is particularly necessary for enterprises to issue renewable energy subsidies in large quantities.
In the long term, the reduction of on-grid electricity prices will prompt the strategy of power generation enterprises to shift from scale expansion to cost reduction, and realize the transformation of new energy. Two transformations from scale expansion to quality and efficiency development, and from a high-subsidy policy-reliance model to a low-subsidy competitiveness improvement model
Question 8: What signals are sent by the National Development and Reform Commission holding two coal meetings a week? First, it is more important. Focus on using market-oriented and legal methods to reduce overcapacity. The meeting pointed out that we must follow market rules, give full play to the decisive role of the market in resource allocation, and eliminate backward production capacity through the survival of the fittest. At the same time, we must better play the role of government and further strengthen market supervision. , continue to increase the intensity of supervision and law enforcement on environmental protection, land, quality, safety, energy consumption, etc., always maintain a high-pressure posture, resolutely and seriously investigate and punish any violations found, and force backward production capacity to accelerate the exit.
The second is. Adhere to the effective release of advanced production capacity on the premise of ensuring safety and reducing replacement.
Safety production is the red line and bottom line, and volume reduction and replacement are the basic requirements for new production capacity during the "Thirteenth Five-Year Plan" period. Any measures to release production capacity must be based on safe production and volume reduction and replacement. The meeting requested that relevant departments and local governments should, in accordance with the requirements of relevant documents, accelerate the verification of the production capacity of qualified high-quality coal mines, accelerate the construction and joint trial operation of approved projects, and accelerate the promotion of the National Development [2016] No. 7 document. Approval of projects that are implemented and meet conditions.
The third is to take comprehensive measures to promote the return of coal prices to a reasonable range. The National Development and Reform Commission recently issued the "Notice on Accelerating the Signing and Strict Implementation of Medium- and Long-term Coal Contracts," which clearly requires all parties involved in production and transportation to speed up the signing of medium- and long-term contracts. More than 75%, the contract performance rate should not be less than 90%, and all localities are required to establish contract performance assessment and evaluation measures, and implement necessary sanctions on enterprises that fail to sign and perform contracts. This meeting proposed that we should organize and carry out investigation and supervision of the signing and performance of medium- and long-term coal contracts, implement necessary punishments for companies that fail to meet the requirements, and urge all parties involved in production and transportation to sign and perform contracts on a larger scale and at a higher proportion. All localities must follow the relevant requirements of the Memorandum on Suppressing Abnormal Coal Price Fluctuations, actively guide coal and related enterprises to establish long-term, stable, mutually beneficial cooperative relationships, and promote the return of coal prices to a reasonable range, especially thermal coal prices into the green *** zone.
The fourth is to scientifically grasp the degree and pace of overcapacity reduction. The meeting emphasized that all regions should scientifically grasp the timing and rhythm of overcapacity reduction based on the actual supply and demand in the region. The timing of overcapacity reduction tasks should focus on effective connection with continuing resources. We must focus on removing "zombie enterprises" that have been suspended for a long time, coal mines that violate laws and regulations and do not meet standards, coal mines with low safety and high risks, and other coal mines with backward production capacity. In areas with severe overcapacity reduction and high coal supply pressure, it is necessary to consider in advance the replacement of resources and transportation capacity after the withdrawal of production capacity, and formulate corresponding supply guarantee plans. It is necessary to use the off-season to increase coal storage in power plants to a reasonable level in advance based on resources and transportation capacity.
Fifth, vigorously promote the development of clean energy. It is necessary to further optimize power grid dispatching, establish a cross-provincial and cross-regional peak shaving and reserve resource sharing mechanism, effectively ensure that clean energy is prioritized on the Internet, carry out pilot projects of clean energy peak shaving power plants on a larger scale, alleviate the abandonment of wind, light and water, and effectively Reduce thermal power output and reduce thermal coal consumption. It is necessary to establish an incentive mechanism for peak-shaving units in accordance with the principle of "whoever adjusts the peak value will benefit". The meeting requested that the clean energy spot trading pilot be launched as soon as possible, the transaction scale should be gradually increased, the scope of the pilot should be expanded, and the ancillary service trading rules should be improved. At the same time, it is necessary to promote key coal-using enterprises, including power plants, to tap their internal potential and further reduce the demand for thermal coal through energy conservation and consumption reduction.
Sixth, use greater efforts and more supporting measures to promote the merger, reorganization, transformation and upgrading of coal enterprises. Encourage the development of coal and electricity joint ventures, and further promote the integrated development of coal and electricity integration, coal coke integration, coal chemical integration and other industries; vigorously promote the merger and reorganization of coal enterprises with different types of coal, different scales, different regions, and different ownerships, forming several special characteristics. Large coal enterprise groups; encourage companies with different ownerships to participate in each other's shares, develop mixed ownership, and achieve quality, efficiency, transformation and upgrading. The meeting emphasized that major coal-producing regions should take advantage of the current important strategic opportunity period to study implementation plans and specific measures, and make successful cases in promoting upstream and downstream coal joint ventures, mergers and reorganizations, etc.
Seventh, further strict safety production requirements. Urge coal enterprises to strictly implement the safety production responsibility system, resolutely prohibit the resumption of work and production in coal mines that do not meet the conditions for safe production, resolutely prohibit super-capacity production that increases safety risks, and resolutely prohibit super-layer and cross-border production that increase safety hazards. Coal enterprises should be guided to increase investment in safety, make up for safety debts, further improve safety assurance levels, and resolutely curb the occurrence of major accidents. At the same time, enterprises must be urged to treat safety inspections more scientifically. Except for coal mines where safety hazards have been discovered, safety "physical examinations" cannot be handled by suspending production in a concentrated manner. Safety hazards must be found under normal production conditions and safety hazards must be ensured. ways to manage safety hazards.
