Series of good news shows that countries have solar power on a very important position

May 23 held a State Council executive meeting made ​​it clear that " self- supporting solar and other new energy products into public facilities and family ." From which we can clearly appreciate the country will accelerate the development of solar distributed generation .

In fact , the favorable development of distributed power generation is not limited to this. Back in April , " distributed generation management approach " and " and network management approach" Bill had been introduced to the public for comments. And subsequently , "renewable energy quota system ," the discussion paper issued in early May and is expected to begin early next year I implemented .

Series of good news shows that countries have solar grid tie inverter power on a very important position , and began to increase efforts to promote the development of solar distributed generation . Distributed generation is relative to the centralized power plants in terms of . According to " distributed generation and network management approach ( draft ) " , " distributed generation " is defined as : Located near the location of the user , not to the large-scale long-distance transmission of electricity for the purpose of the power generated by the user in addition to their own use and the nearest use , the excess electricity fed into the local distribution grid power generation facilities , power generation systems or power output of the energy cascade utilization of integrated multi- CISS .

Market Distribution of electricity and solar energy distribution does not completely coincide . As the larger eastern electricity , land prices are more expensive , if the construction of large-scale centralized ground station will greatly improve the cost , is not conducive to large-scale promotion of solar power ;

Rich in solar energy development in the western region centralized power stations, long-distance transport of electricity will emerge loss problems . Therefore, the state of solar distributed generation policy guidance and support , and promote the domestic PV gridtiepowerinverteronline market installed capacity from large centralized to distributed power station roof and small changes in public facilities , in fact, fully in line with the status quo of China's PV market development law .

According to experts , the domestic development of distributed power plants need to focus on solving three problems , namely policy areas , pattern links, technical aspects . At present, the European and American market has formed a very mature about the distributed generation model, through the planning guide , incentives, reasonable price mechanism and other means , many developed countries, the proportion has been fairly distributed energy high . For example, the amount of distributed generation in Denmark even more than half of total electricity generation .

With the domestic policy-oriented determination of foreign advanced model will be the promotion of rapid replication , so now the most important and need to be addressed , but is that technical aspects of the problem . At present, because solar power itself is unstable, the domestic terms of the relative aging power grid will have a relatively large impact , even a threat to network security issues. To solve these problems , in addition to hardware upgrades from the grid , the solar power system side , especially the technical reliability of PV inverters is particularly important .
