The “Fifth Dynamic Innovation and Development Forum” hosted by the Chinese Transformation News Agency “Motivation Development” weekly and hosted by the Beijing Institute of Development and Technology Research and Development was recently closed in Beijing. Sun Yong, former vice president of the Power Planning and Design Institute, pointed out in his purpose speech that focusing on the hot energy generation is to concentrate power generation and energy storage As a complete renewable power generation method, the power output is stable and reliable and has superior adjustment function. It can be used as the main force in the power system to bear the base load or the C-shaped load. It can participate in the primary and secondary control frequency of the power system, and can reduce the capacity of the power system to energize the power station <a The demand for volume is to set up a light-concentrating heat generator set at the power transmission channel outlet of the South East Sugar daddy to significantly increase the renewable power and power ratio of the loading channel.

National Energy Research Institute and Green Intelligent Bank believe that with the emergence of new power generation devices such as photovoltaics and wind power, the demand for peak power supply will also rise significantly. As a new power supply with green color and adjustable performance, light heat will play the main color in the future dynamic system.
Optical heat generation enhances stability of the network
Pinay escortThe optical heat generation unit that is equipped with a heat system can maintain a stable power output, can act as the main force in the power system to bear the base load, or as the peak adjuster in the power system to bear the Centre load. Compared with coal-fired power generation, the optical heat generator set adjustment characteristics are better. It can quickly respond to the Internet load needs and quickly adjust the output of the machine set, and can participate in the power system peaking and frequency adjustment.
The optical heat station is one of the few technical plans with energy storage efficiency in cleaning power, which is conducive to the exposure of wind and light collecting circles. The adjustment of power output during power generation reduces the proportion of wind and light disposal, and enhances the stability of the network. According to Sun Jin’s calculation, taking Xinjiang Internet as an example, installing an optical heat generator set of 5 million kilowatts can reduce the abandoned optical power by 37.6%.
Figure 1 The relationship between the addition of new optical heater in Xinjiang and reducing the proportion of abandoned optical power.
In the “Zhangjiakou Power Transformation Strategy in 2050” issued by IRENA of the International Renewable Dynamics Agency, under normal circumstances in 2035, the proportion of renewable dynamics reaches Sugar baby53%; while by enhancing the energy or applying the energy, the renewable dynamic component will continue to increase to 75%. By comparing the amount of power generated by one force, the growth of light and heat generation is clearly visible, and it is one of the useful techniques to support renewable dynamics after coal electricity is reduced.

In addition, in the context of the suspension of maximization of coal-electrical installations, the delivery of renewable power ultra-high pressure transmission channels will be affected by the lack of peak power. By building optical heat The station replaces the suspended coal power, and the transmission of transformable renewable power such as wind and light will be strengthened.
The National Energy Development Research Institute and Green Intelligent Bank believe that the energy storage capacity of light-heat power generation equipment has great advantages in large-scale energy storage, and is suitable for adding wind to the base load and peak-pressure power supply. href=”https://philippines-sugar.net/”>Sugar daddy and photovoltaic power generation equipment scale and reduce the abandonment rate, which has the main meaning of slowly reducing the proportion of coal and electricity, reducing carbon emissions, etc.
Our photothermal power generation has a huge potential
Similar to the types of wind and photovoltaic, our country’s photothermal resources are also very rich. All photothermal power generation can be determined by the direct emission of the local solar, Inner MongoliaThe annual direct solar radiation volume in the western part of the autonomous region, the southern part of Gansu Province, the Haixi Prefecture of Qinghai and the eastern part of Xinjiang Autonomous Region exceeds 1,800kWh/m2, which is very suitable for the construction of optical heat generation projects. According to the statistics, the above four provinces are suitable for building optical and thermal power generation bases of about 780,000 km2, and the optical and thermal power generation project can be built at about 7,800 GW.

According to the calculation of Sunban, considering the optical resources, ground disk resources and water resources, the capacity of my country’s optical thermal power generators can achieve 12 million, 22 million kilowatts, and 52 million kilowatts respectively in 2030, 2035 and 2050.
The landing of capital has a large scale application
According to the data in IRENA’s “RE Capacity Statistics 2019”, the number of new installations in the world and China from 2010 to 2018 is shown in Figure 4, and the number of new installations in China accounts for Figure 5. With differences with photovoltaic power generation, photovoltaic power generation has grown significantly since 2013 and has continued to develop at a high level. China has been leading the world in the long term.

Comparison of the supplementary policy, photovoltaic power generation launched the air station’s standard price policy in 2011, with a supplementary strength of 1.15 yuan/KWh, 2013Sugar daddy dropped to 1 yuan/KWh, and after 2014, a certain western region dropped to 0.9 yuan/KWh, and then fell several times since then until it adjusted to 0.5 yuan/KWh in 2018. In 2016, the OPEC released a 1.15 yuan/KWh supplement policy for demonstration projects, and reached Escort manilaNo new policies have been released yet.
The National Institute of Energy Development and Green Energy Database have found through sorting and sorting that photovoltaic and photothermal start almost at the same time in China, but the gap was quickly pulled by agile after 2013. Some bottom lines can be found in Figure 6. The price of photovoltaic system continued to decline, with an average drop of 52.9% in 2018 compared with 2013, and the cost of photovoltaic system fell by only 17. .5%.
The significant decline in power station system capital is due to the expansion of scale and perfection of industry links. In terms of photovoltaics, it is one of the few production and application ends in China. According to statistics, in 2013, Chinese enterprises accounted for 70%, 60% and 60% of the world’s top ten manufacturers of solar silicon wafers, batteries and components. That year, the new capacity of China’s photovoltaics accounted for the global shareSugar baby just exceeded 30%.

The optical thermal industry chain is not as powerful as photovoltaics. It is clear that the broad operation of enterprises that focus purely on the optical thermal power market is difficult, and the domestic existing market lacks to support their healthy development. Correspondingly, most suppliers are not only relying on the optical thermal market, and due to their unlimited scale, their investment in the optical thermal TC:
