The hottest new energy is not a feature, but a sta

New energy: not features, but standard configuration

in many people's impression of different test methods, characteristic towns have officially appeared in official documents for the first time. In July 2016, the three ministries and commissions jointly issued the notice on developing characteristic towns

this document with less than 2000 words puts forward framework requirements for the construction of Characteristic Towns in terms of industry, environment, culture and services, but does not put forward any opinions or plans for the production and use of energy in the towns. It only points out in the "guiding ideology, principles and objectives" that characteristic towns should meet the goal of "green ecology, beauty and livability"

in the next practical operation, the builders of the characteristic town found that if they continued to use coal, oil and other resources to share the solutions to the failure of the tensile testing machine, the requirements of "green ecology" would not be met. Therefore, many towns have to start to adjust, mainly from two aspects: one is how to establish a clean energy supply system, and the other is how to create a clean and sustainable way of energy use

it can be seen that new energy has not only been the characteristic industry selected by some towns, but is expected to become the standard configuration of most characteristic towns

first deal with the low configuration, and then consider the high configuration

to take new energy as the standard configuration, we must first clarify two concepts: high configuration and low configuration

at present, the builders of some characteristic towns are very determined to use energy, and even directly propose to make a certain area "zero carbonization". With the current technological level of new energy, it is not impossible to achieve zero carbon, but the actual operation is not easy. Because the prospect of new energy development depends largely on the location, population, industry and other conditions of a place

first look at the location. As we all know, the fossil energy model is easy to replicate, because it is less affected by geographical factors. As long as there is railway and road transportation to ensure the sustainable supply of coal, thermal power plants can be built. However, new energy is not. It is greatly constrained by regional resources. Just think, if there is no geothermal resources in an area, it is difficult to realize geothermal heating. Therefore, the development of new energy needs to be closely combined with local conditions

the second is population. Under the same resource conditions, the construction direction of the energy system will be different with different population density. Especially in terms of the matching of new energy - the energy supply capacity of new energy is limited. If the population density in this area is too high, new energy cannot meet the demand

the third is industry. The smooth development of new energy is closely related to the local industrial base. For example, in Shandong and Hebei, which have a good agricultural foundation, the local straw production is large, and the new energy system based on biomass power generation is easy to establish

from this, it is not difficult to see that zero carbon is more like "high allocation" for characteristic towns, which requires more costs and resources to achieve, while energy planning that adapts to local conditions and combines industrial characteristics can be considered as "low allocation". "High configuration" is good, but it is not economical and difficult to promote for most towns. Therefore, at this stage or for a period of time in the future, it is advisable to start with the following three aspects, first complete the "low configuration" version of the energy solution, and then gradually advance to the "high configuration" solution

the primary design is the energy system, which can choose different power generation methods according to the resource characteristics of different regions, so as to realize the reasonable allocation of photovoltaic, wind power, energy storage, biomass and other new energy, and make the economy reach the best state

the second thing to consider is the heating system. In future towns, coal-fired boilers must not be the first choice, but choose resources such as gas, ground source heat pump and biomass according to cost and resources, or take overall consideration and use some of the above three technologies to achieve the best

the third thing to consider is the transportation system. At present, the planning of most characteristic towns in China generally does not involve green transportation, and the current or future means of transportation is still dominated by fuel vehicles. But in fact, the energy consumption of the transportation system accounts for a considerable proportion of the total energy consumption, and is related to the energy system and heating system. Therefore, in the future clean energy security system of small towns, charging facilities and green transportation need to be considered, planned and constructed in advance

to have a sense of existence, we need a sense of participation

if new energy wants to become a standard configuration, it also needs to be recognized, especially from the public. To do this, we must first let people see and touch

therefore, "visible new energy" needs to be one of the basic standards in town planning. Taking photovoltaic as an example, designers can create a first impression of the ubiquity of new energy by presenting some display products, such as erecting photovoltaic on the roof and Installing Photovoltaic trees

but compared with it, the more effective sense of existence comes from the ingenious combination of convenient facilities and photovoltaic products, such as the establishment of photovoltaic walkways and photovoltaic corridors. People can not only use and enjoy their functions and convenience, but also intuitively see photovoltaic products

in addition to "seeing", if you want to brush out the sense of existence more effectively, you should also try to involve the people

unlike end consumer products such as consumer electronics and household appliances, energy itself is invisible. But in fact, energy is not for others to see. In the end, it will be used. In any city, we can't see electricity, but we enjoy the convenience of electricity all the time. Therefore, by making the public feel the value of energy through participation, we can also strengthen the sense of identity for new energy

for example, through energy interconnection, combining the energy system of characteristic towns with finance is a public participation model

in this mode, the operators of the town plan all photovoltaic panels for the government, hospitals and other public areas. The cost of purchasing and erecting photovoltaic panels can be raised through the subscription of residents of the town rather than being paid by the government or the operators. After subscription, photovoltaic purchasers become photovoltaic owners. They can monitor the operation of the purchased photovoltaic in real time through the energy interconnection system, and regularly obtain part or all of the income generated by photovoltaic products such as pipe stretching and tightening fixtures

in the process of subscription, monitoring and collection, the public's own sense of experience of new energy will undoubtedly be strengthened. This sense of participation will be more obvious if trading and social functions are added through energy interconnection

through transactions, PV buyers can choose different objects to sell or give away the electricity they generate. In the transaction, people talk and communicate with each other because of new energy. With the increasing number of people participating in the transaction, social functions will be established, and people's intuitive feelings about the low-carbon and clean functions of the town will inevitably deepen

how to excavate and how to benefit

we have been deeply engaged in high-precision catheter processing technology for many years. According to the existing technical conditions, the town can achieve the goal of energy-saving, green and clean development through the overall optimization of the energy system. However, at present, the energy planning of some characteristic towns is still blind, because they do not know exactly their own energy potential and energy needs to be absorbed, so it is difficult to start planning

the key to solve this problem is to accurately mine and plan the energy carrying capacity of the town through data search, and form an economic and feasible energy solution

in this regard, power companies may have great potential in the energy planning of characteristic towns

taking photovoltaic data as an example, power companies can collect substation data and load data near the town, and then combine them with roof data to analyze how much photovoltaic can be installed in the town. Next, the data can be optimized and adjusted by the comprehensive energy design software to make a comprehensive design scheme based on photovoltaic and combined with multiple energy sources

at this stage, for most towns, this comprehensive energy solution will be more feasible and economical than the 100% renewable energy solution

in terms of cost, as mentioned above, if only 100% renewable energy is produced, the technology is relatively difficult and the investment is high. Even if the initial investment problem can be solved through crowdfunding, whether the risk control ability is in place will also affect the determination of investors. In contrast, a high proportion of renewable energy solutions can not only adapt to local conditions, but also reduce costs through the comprehensive application of various technologies

from the perspective of income, once the comprehensive energy supply is made, it means that the operator will not only complete the energy supply, but also integrate all links such as water supply, heat supply and waste treatment with high energy consumption into the unified system. After the overall design, the water supply, drainage, heating and waste disposal of the town will achieve the lowest energy consumption, saving operators a lot of costs. At the same time, the business scope of operators will rapidly expand from selling electricity in the past to providing comprehensive energy efficiency services
