Distributed PV - struggling Grid

In the recent introduction of the " relevant State Council on promoting the healthy development of photovoltaic industry a number of opinions " and highlighted the priority support distributed photovoltaic power generation demonstration ( city ) County , to create demonstration areas and demonstration towns. This is also in line with the 2013 series of policy direction , which is to support the development of distributed photovoltaic electricity load priority areas to electricity in many places as a demonstration. It also reveals national guidance on the direction of the grid is the emphasis on encouraging self-occupied , local consumer satisfaction .

We know that Germany is the world's most widely distributed photovoltaic country , in a distributed application, whether China is likely to reach the German degree ?

A well-known German inverter with charger China sales manager told the reporters: " Germany and China Power Grid Grid exactly the opposite. Traditional energy generation costs in Germany is more expensive, more willing to buy solar power grid . Conventional energy generation costs around € 0.3 , the cost of photovoltaic power generation is 0.1 euros, more willing to buy not only the grid photovoltaic power generation, and even users are more willing to use photovoltaic energy storage device to store , rather than sold directly to the grid . "

Germany benefited from the early years of this phenomenon to the mandatory access policy . In the early stages of development , the high cost of photovoltaic power generation , when the coercive measures taken in Germany , compulsory acquisition of photovoltaic grid and take diminishing subsidies . Germany 's feed-in tariff (Feed-In-Tariff: FIT), completely solve the problems of renewable energy power generation and network problems for PV offers users a guaranteed return on investment , which greatly promoted the German PV market expands, so Germany, the rapid growth of the world's largest PV market .

And China Is it possible to like Germany , so that distributed photovoltaic power generation and network secure, thus achieving large scale to promote the development of distributed generation , it also requires the test of time . State Department counselor , · Advanced Renewable Energy Association believes that China in the early development of distributed photovoltaic power generation , the State Grid Corporation Changwang systems lack adequate preparation, the full implementation of the short term is not realistic . Because in the past to treat national network of distributed photovoltaic been negative attitude in this regard and did not do much preparation and research. Also due to policy changes too fast , and require the county to provide wind grid tie inverter companies to accept applications and network services , this process takes from the national to the provincial, city and county level , a short time to implement some of the problems encountered .

Although the national grid passive attitude toward distributed photovoltaic power generation, but the general trend under the National Grid 's attitude began nearly two years has shifted . October 26, 2012 , the National Network officially announced support for the construction of distributed photovoltaic power stations and photovoltaic power generation and network related comments and publish distributed photovoltaic power plants connected to the grid of the relevant standards, allowing six megawatts scale distributed PV grid waived . So far , the Chinese all over the spate of distributed photovoltaic power generation and network news.

National Grid persons who requested anonymity told the publication , said: "Our country is different from the United States and Europe , the foreign take supporting gas engine , power grids and strong regulation , the regulation for the absorption of distributed generation capacity is relatively strong our country needs in this regard a lot of input , and this problem is more complex , the need to coordinate and discuss various departments , the process is still quite long . "

· Advanced believes that the most practical approach in line with China should first select the different types of regions, really good job in pilot work , the accumulation of experience of the pilot , the pilot lessons learned , and related technical standards, construction project management standards, user service , post- assessment acceptance, operation management, and other aspects of exploration and improve gradually in the nationwide promotion . This view with the current Chinese frequently introduced a series of policies coincide.
