Energy Internet building new forms of new energy consumption

Polaris solar PV net news: encouraged by subsidies in the past few years China’s wind power, photovoltaic achieved rapid growth. The strategic action plan for energy development (2014-2020) points out that, by 2020, wind power installed capacity reached 200 million-kilowatt, PV installed capacity up to 100 million-kilowatt per cent. “Thirteen-Five” new energy will steadily increase during the period.

New energy capacity growth too fast, all digestion and supporting a number of local power grid is not yet complete and other reasons, the new energy industry currently faces two major dilemma: abandon wind, abandoned is serious, especially in the Midwest; lack of renewable energy fund, subsidies are not in place.

In February 2016, China issued on advance Internet “+” smart energy development guidelines, establish new energy consumption patterns of an Internet and use Internet to improve energy efficiency.

New energy capacity growth

Record high wind power capacity in 2015. Influence of wind power price adjustment is expected in early 2016, new wind power installed capacity 2015 infrastructure hit a record high. Domestic capacity 2015 32.97 million-kilowatt, an increase of 66. 43% total on-grid capacity was 1. 2.9 billion-kilowatt, an increase of 33. 86%. By the end of 2015, wind power installed capacity total power capacity of 8. 6%, wind power electricity generation accounted for 3 of electricity. 3%.

In 2015, continuing high growth of the photovoltaic industry. Domestic capacity 2015 15.13 million-kilowatt, an increase of 42. 74%, cumulative installed capacity reached 43.18 million-kilowatt, an increase of 53. 94%. Among them, the PV power station 37.12 million-kilowatt, distributed by 6.06 million-kilowatt. By the end of 2015, PV installed capacity total power generation capacity of 1. 0%, PV power generation total generation 0. 70%.

New energy development still faces many problems

1. Abandon wind, abandoned optical phenomena are still serious

Since the main concern in the process of construction of new energy resources and neglect the market creates a scale of excess, causing power to send out, appeared to abandon the wind, abandon light problem.

2015 wind up wind power situation intensifies, abandoned when the wind power 33.9 billion-kilowatt for the year, up 21.3 billion-kilowatt when mean abandon wind 15%, 7% over in 2014. 2015 national annual utilization hours average for photovoltaic power generation 1133 hours, national “abandoned” phenomenon is not too serious, but more serious in some areas in the Northwest to abandon optical phenomena, such as Gansu abandon rate 31%, Xinjiang autonomous regions abandoned rate was 26%.

2. Subsidies in arrears, subsidy policy faces great challenges

State subsidies are levied in the country of origin for renewable electricity surcharge subsidy is the amount of renewable electricity prices with local coal benchmark price difference.

Policy since the implementation of additional charge after 5 adjustments, currently 1. 9 cents per kWh. According to the Institute of national development and Reform Commission statistics, by the end of 2014, renewable energy fund subsidies corporate default reached 17 billion yuan in 2015, renewable energy development fund subsidies of almost 50 billion yuan, but the cumulative gap of about 40 billion yuan. According to the “Thirteen-Five” program, when 2020 wind power generation reached 460 billion-kilowatt, while PV power generation reached 160 billion-kilowatt, such as all forms of demand subsidies to renewable additional settlement, subsidy gap will further widen.

Solution: energy Internet

1. Countries pushing the energy Internet

Building energy Internet can solve China’s energy consumption and production of geographical mismatch, and improve resource utilization. On February 29, 2016, the national development and Reform Commission, the energy Bureau, jointly issued by the Ministry on promoting “Internet +” smart energy development guidance (hereinafter referred to as the opinion), promote energy infrastructure, reasonable and open, promote the integration of energy production and consumption, increase public participation and speed up the formation of an open, shared energy industry as the main features of the development of new forms. Views, 2016-2018, advancing energy Internet pilot work; 2019-2025, with the focus on energy diversification, the development of the Internet.

2. Energy Internet to radically improve the efficiency of new energy power generation

Distributed energy resources when running alone, and its output random, intermittent and fluctuating, distributed energy access the traditional grid system, security and reliability of power system will be threatened. Power grid to ensure the security of transmission lines, only reduce the wind power, photovoltaic electricity, resulting in abandoned, abandoning the wind phenomenon. In energy under the condition of Internet, distributed and micro-grid technology, new energy generation can be achieved near elimination, power, significantly improve energy efficiency.

3. Setting up electricity sales company, through value-added services to achieve comprehensive cost reduction

On December 24, 2014, Premier Li presided over a State Council Executive meeting, “new reform” programme adopted by the principle on March 15, 2015, and some opinions on further deepening the reform of electric power (“2015”, 9th) promulgation of 2015 years, modified 10 documents have been issued.

Under the “modified” files, new placing power markets will be open, there are five types of enterprises to enter incremental placement business, including power plants, high-tech economic development zone, industrial park, or, user or distributed energy micro-grid system, public services such as water supply, gas supply, heat supply and energy service companies, such as social capital.

At present, the average price of China’s wind power more expensive than thermal power 0. About 2 Yuan/kWh, average electricity price of photovoltaic power generation thermal power costs 0. About 6 Yuan/kWh. New energy needs on the one hand the Government continues to support and encourage the development of the other hand, will go to market in the long term, participate in the bidding. In addition to equipment costs fell outside, the formation of electricity sales enterprises, the provision of value-added services are also integrated new energy enterprises to reduce costs, an important means of participating in market competition. Our Germany Entega company as an example.

Germany Entega company has 1 million customers, 400,000 of which uses 100% renewable power, became Germany’s second-biggest electricity sales of clean energy companies. Entega company providing services there are two: one is the purchase of clean energy generation equipment, production of electricity and another provides services such as electricity, gas, water and heating. Around the company selling electricity and other energy services, the company developed a panorama APP platform, helping customers understand energy usage, to achieve the goal of energy saving.
