How to make the best use of new energy power generation

Abstract: to solve the problem of renewable energy power generation, China cannot copy the foreign model, but needs to go out of China's own way and solve problems in development through the effective combination of subsidy system, quota system, green certificate of power generation and other strategies

according to a statistical data quoted by the media, in 2016, the amount of "wind", "light" and "water" of clean energy in China was about 110billion kwh, and the total amount of "three wastes" exceeded the power generation of the Three Gorges power station in the same year, with fire 4 Preparation and utilization technology of nano and powder metallurgy new materials the utilization hours of electrical equipment also fell to a new low since 1964. Among them, the problem of "water abandonment" is more conventional, with a relatively small proportion, but the proportion of "wind abandonment" and "light abandonment" of new energy is close to 20%, which is indeed an urgent problem to be solved. What is the essence of the "three discards" problem? Is it the sequela of leap forward development? Is it related to "local barriers"? The author believes that these problems need to be comprehensively analyzed from the following levels

"three discards" is essentially the problem of overall electricity surplus, while China's electricity surplus is a short-term phenomenon. The speed and system of economic development determine that electricity is often in surplus or shortage. At this stage, economic growth slows down, resulting in a relative surplus of electricity

it should be pointed out that China's per capita electricity consumption is still relatively low, and excess electricity will not be a long-term phenomenon. The life cycle of hydropower stations and thermal power stations can reach 50 years, and new energy power generation also has a life cycle of about 30 years. It is completely understandable that there are several years of inefficient operation, and their benefits should also be evaluated from the perspective of the whole life cycle. The "13th five year plan" predicts that the power demand will increase by 5%. At this development rate, through appropriate regulation, the current scale of power surplus can be alleviated to a certain extent in the near future, and the "three abandonments" phenomenon will be improved

on the whole, another important reason for the emergence of "wind abandonment" and "light abandonment" is that the country must continue to cultivate the new energy industry and promote the rapid development of new energy. China's new energy manufacturing industry is at the forefront of the world, which is closely related to the government's strong investment and cultivation over the past 10 years. The amount of new energy power generation is related to the income of power generation, and the development of the whole industrial chain cannot be stopped because of this. We should strengthen dust control. We should see that new energy has produced huge environmental and economic benefits, and the consumption problem at this stage is only part of the problem in the development process, which should be judged from a longer-term perspective

the impact of "local barriers" mentioned in some reports on the "three discards" should not be exaggerated. Admittedly, local governments have the pressure of GDP and economic considerations, but more fundamentally, they are still calculating the economy of energy products. If new energy power is indeed the most affordable, local governments will not give it up for nothing. Therefore, exaggerating local protectionism will cover up some problems in the development of renewable energy

it is worth noting that in recent years, the number of hours of thermal power generation has actually decreased more, and the impact strength of the universal testing machine has increased by 160%. Therefore, it is not objective to overemphasize the "three discards" in quantity. With the current volume of electricity in China, the comparison of data can easily reflect amazing results. Take the Three Gorges power station as an example. When generating electricity in 2003, its installed capacity was equivalent to one fourth of the total installed capacity of hydropower in China, but now its proportion has fallen to about one twentieth. In 2016, although the "three wastes" power generation exceeded that of the Three Gorges power station, it was only more than 1% of the country's total power consumption. The author estimated the gap between the actual power generation of thermal power in 2016 and the theoretical power generation calculated according to the highest hours over the years, which is even more than the power generation of India. If you look at the data alone, the phenomenon of "abandoning the fire" is more shocking

of course, the scale of "three discards" is very large, which not only causes serious economic losses, but also has some regrets in the aspect of environmental protection. After all, more renewable power generation can correspondingly reduce thermal power and reduce some environmental pollution. The 13th Five Year Plan period is an important node in China's economic transformation. How to coordinate renewable energy and fossil energy needs the government to make an overall plan from the economic, social, environmental and other levels

compared with many countries, China does have objective difficulties in the consumption of water, wind and photovoltaic power generation. On the one hand, power generation endowments and electricity demand are inversely distributed. On the other hand, there are many constraints on the distributed development of new energy in China. More importantly, the low price of electricity in China has little room for operation. Therefore, in order to solve the problem of renewable energy power generation, China cannot copy the foreign model, but needs to go out of its own way and solve the problem in development through the effective combination of subsidy system, quota system, green certificate of power generation and other strategies
