On March 9th, the national energy administration power reliability management and engineering quality supervision center was held in anhui hefei organization the national electric power quality supervision institutions work symposium, seriously implement the party central committee and state council on the development of high quality major decision deployment, promote implement "on further strengthening the views of the electric power construction engineering quality supervision management, related work, summed up work in 2017, the deployment of 2018 key tasks.

The meeting stressed that the power quality supervision organs should make a solid effort to do all the work in 2018. First, they should consolidate their work basis in accordance with the law, actively handle the registration of independent legal entities, and speed up construction institutions and teams. Second, we should be brave enough to assume due diligence, and work well in quality supervision according to the division of tasks. To accurately grasp the position of the job, take the initiative to complete the relevant rules and regulations as required, and supervise the revision of the outline; 4. Timely completion of quality supervision work information as required. All relevant energy enterprises should fully implement the main responsibilities of quality and safety, take multiple measures, strengthen management, and resolutely guard against preventing major quality and safety accidents.

The department of electric safety supervision of the national energy administration, the east China energy regulatory bureau, the power quality supervision organs, and the relevant responsible members of the electric power enterprises attended the meeting.

Recently, a seemingly ordinary news touched the future trend of the distributed photovoltaic market. National energy bureau agreed to electric power planning and design institute for setting up new energy given monitoring warning center ", "national comprehensive monitoring the national new energy given conditions, with the national new energy for the future development and prospect of given systematic analysis. The background of this early warning center is distributed photovoltaic, especially in the household pv market unprecedented explosion!

The popularity of distributed photovoltaic market can be used to describe the great leap forward: experienced technical and engineering managers in particular, companies are digging this kind of person, monthly salary plus extra money, more than the average annual income in 200000; Developers with a large number of rooftop resources are the second most popular, similar to the real estate project development process, with the ability to play the game and the capital and resources. If you do well, you can do Polo for a year. The household USES the photovoltaic field to be more lively, the first surge of solar hot water and home appliances comes in, and then the insurance direct sale, then the wedding photography, clothing wholesale... It's not lively. With the low pv threshold and lack of supervision, too many people come in with the idea of "making a profit". Fake fake degradation component, the rain will rust bracket screw, with a variety of purpose "free installation" marketing scheme, non-standard stents and electrical equipment installation roof collapse, caused by short circuit on fire, support the "flying", screamed!

A photovoltaic expert said: "in the case of a non-professional people who are rushing into the market, the first is the need for the state to formulate mandatory security acceptance standards as soon as possible. The second is the need for technical and engineering professional training; Third, there are institutions to lead the market regulation supervision; Let the counterfeit and the unsafe hidden trouble from the source to snuff out!"

Words are referred to as the "easy come, easy go", household photovoltaic market in the process of surge, a large number of user to regional integration rapid expansion, at two years three billion to build rich myths stimulates every pv practitioners. According to industry experts, large distributed roof has robbed it, the high quality of small and medium-sized industrial and commercial roofs will be robbed empty within five years, the rapid growth of household photovoltaic probably in two or three years, five years even after will enter the stock of distributed photovoltaic market "sharing operations" era

Power station to the surface buoy, from the ground from roof to the door with industry and commerce, the development of the photovoltaic market will gradually enter the field of BIPV, distributed photovoltaic (pv) from "pure profit driven" into the "efficiency and beautiful two-wheel drive" new age of pv market development will also tend to be more mature and slow, and a large number of professional pv practitioners will automatically escape.

China's decentralized wind power has been slow to develop since its start in 2012, but the wind industry is eager to replicate the successful experience of distributed photovoltaics due to the severe impact of large-scale projects. Distributed wind power, although the total capacity is small, can take advantage of the existing power grid in transmission have been completed, more flexibility, achieving the effective utilization of wind energy resources scattered and given on the spot. Because of this, China's distributed wind power has great potential for development.

Distributed wind power development: how to break the shackles to realize the potential?

Decentralized wind power projects are a unique type of onshore wind power projects in China. According to the definition of the national energy administration at the end of 2017, the distributed wind power refers to the wind power project with an access voltage level of 35kV and below, which is completely consumed in the local area and does not send electricity to the high voltage level.

, distributed wind power currently in China's wind power capacity of less than 1%, but for the need to improve the development quality and optimize the layout of the Chinese wind power industry, development of distributed wind power is to improve the utilization rate of wind power, the inevitable need to promote industry development. The relative lag of its development level indicates the great potential of development.

The has obvious advantages, but distributed wind power has been slow to develop in China, the projects have been put into operation in the capacity of less than 1% of the total capacity of wind power grid, is far less than the construction scale of Europe. According to qin haiyan, secretary-general of the China renewable energy association's wind energy committee, there are two main reasons for this:

One is wind power development in China started in the west, large wind power development companies used to through massive investment in terms of centralized development, individual distributed wind power projects of small, relatively low investment success, enterprise's enthusiasm is not high.

Distributed wind power development: how to break the shackles to realize the potential?

The second is that the decentralized wind power project still adopts the approval requirement and process of centralized development, which leads to low efficiency and increased up-front cost.

In addition, China has not formed a relatively perfect standard system and management standard of distributed wind power technology to guide the overall development of distributed wind power. This includes unclear definitions of wind power, and the current definition is too broad to lead to differences in understanding. The development of decentralized wind power planning and power consumption in provinces and regions is lagging behind, and government guidance is not enough. The promotion of distributed wind power does not combine with the development of county economy, especially the interests of rural and peasant households, etc.

In order to solve the above problems, qin hailu believes that the development of decentralized wind power must adhere to the ideas and principles of "centralized planning, batch approval and integration with local economic development".

First, decentralized wind power projects are decentralized and small, and must be centrally planned so as to achieve economic and efficient management and ensure the orderly development of projects.

Distributed wind power development: how to break the shackles to realize the potential?

Second, the project should be packaged and approved in a county area to simplify the early procedures and avoid unnecessary costs.

Finally, can be based on the experience of the foreign community wind power development, through the land, the PPP mode, and so on ways to increase local participation, and will be distributed around the wind power development and tourism development, the characteristics of small town construction, the people's livelihood improvement works, such as, the combination of the local community and residents benefit, promote local economic and social development.

According to the 13th five-year plan for wind power development, by the end of 2020, wind power generation will be guaranteed to reach 420 billion kilowatt-hours, or about 6% of the country's total electricity generation. Immediately, the national energy administration issued by the middle of 2017's "about accelerating distributed access to wind power project construction related requirements" puts forward, distributed access wind projects to meet the requirements, without being limited by the scale of annual guidance, were seen as key symbol of distributed wind power into the fast lane.

And published in the march of the 2018 energy work guidance on notice for further pointed out the direction of the wind power development: focus on solving the problem of clean energy given to priority to the development of distributed wind power. From the demand side, the development of wind power in China has gradually shifted to the central and eastern regions, and distributed wind power is the new main force. With the characteristics of close to load and short construction period, the dispersive type will continue to spread in central China as the core increment of wind power. The detailed rules for future development of distributed wind power are expected to be issued as soon as possible.

Obviously, although the development of decentralized wind power in China has been slow in recent years, the development of decentralized wind power is the general trend. Today's distributed wind power, with policy support and market demand, is likely to become the next industry outlet.

As central to determine the depth of the "one of the three areas, three states" in poverty-stricken areas and southern xinjiang four state in rural energy resource conditions good to take the lead in building a batch of photovoltaic (pv) pilot for poverty alleviation, millions of farmers out of poverty for the southern xinjiang lit up momentum.

But experts have called for the construction of a "dormant power station" to prevent "a rush".

Like many villages in southern xinjiang, the village of yabai village in zuler county, xinjiang, has a lack of water, a weak industrial base and a 36 percent incidence of poverty.

In 2016, the working group of xinjiang electric power company "visited the People's Republic of China" to coordinate the photovoltaic enterprises to build the integrated photovoltaic precision poverty alleviation project, with the installed capacity of 166 kw.

The working group said that the project generated more than 50,000 kilowatt-hours of electricity and the income of 40,000 yuan was transferred to the village to help the poor. This year, the pv power station is expected to earn 180,000 yuan, which will be calculated at 3000 yuan per household, and 60 households will be poor.

In the photovoltaic power station operation maintenance room, agtech BuLiZi o in accordance with the village committee director, wood said, pointing to a computer screen: "the higher the green column, the more electricity, the village collective income is higher, helping the poor.

After months of training, some of the monitoring and maintenance of the plant has been handed over to the farmer, who is used to a hoe.

More and more villagers hope to learn technology as the photovoltaic power station gradually produces benefits. Up to now, more than 200 villagers have participated in electrician, welding and computer training courses. More than 20 of them have signed employment contracts.

In the village of tallek, in the town of itimoko in yagi prefecture, in the kashi area, the family of 33-year-old menisha muzi, a family of five, has lived on several acres of land and odd jobs for many years.

After installing the photovoltaic panels, she said, the home alone received 720 yuan in just two months. She said she hoped to get out of poverty, and she would wash the dust on the photovoltaic panels every week to improve the efficiency of electricity generation.

Published by the state development and reform commission (NDRC), January 1, 2018 put into operation in the future of photovoltaic power generation project of electricity per KWH fell 0.1 yuan, after January 1, 2018 put into operation, the "spontaneous for private use, Internet access, allowance," model of distributed photovoltaic power generation project electricity subsidy standard reduced 0.05 yuan.

Latin American association of composite materials (ALMACO) in 2014 Brazil international building materials exhibition (Feicon) on 330 square meters of space, in the form of "residential area" performance fiber reinforced composite materials (FRP) is how to become a part of the People's Daily life, while many people don't realize.

"It's impossible to imagine what we would have without these materials in our lives, and the construction industry is one of the indispensable examples of composite materials." "The sink, sink, toilet seat, water tank, tile, and even the entire house are made of resin and fiberglass - fiberglass reinforced plastic," said Gilmar Lima, President of ALMACO.

The "residential area" will consist of a house and a school. The construction system of the two buildings was approved by the Brazilian government Program "Program My House" and "My Life and the National Education Development Fund" (FNDE). The space area will also include a health centre, a shop and leisure area.

"The entire exhibition area will be based on composite materials. From telegraph poles, mini wind turbines, toilets and traffic signs, to bus stops and decorations, all items will be made of composite materials. Lima says the "Compocity" mini-city, built by ALMACO in 2012, is based on the same idea. "It was about $800 million in business, and the expectation is that it will be at least as good as it was before."
