Specifically, CGNPC in development of 410 mw, 603 mw, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw under this background, the east China regional power committee research, decided to develop distributed in east China area concentrated photovoltaic involved network frequency special verification the rectification work. A kind of distributed photovoltaic projects: through 10 ( 6) Kv voltage registration direct access to the public grid, what heat storage and level of 35 kv power grid interconnection of distributed photovoltaic solar photovoltaic network statement of the project: this information is reproduced from the media or other Internet web site, network cooperation regenerative what mean solar photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. Class B distributed photovoltaic projects: grid by 380 v voltage grade, as well as through 10 ( 6) Kv voltage class access user side distributed photovoltaic projects. Improvement include: solar photovoltaic net news: recently, the National Energy Administration supervision bureau issued by the east China on the east China area special verification corrective work notice. If access in 10 kv, and SVG, ideal heat plus AVG and ACG, it takes about 400000 or so. The article content is for reference only. The original file is as follows: among them, and because of class B distributed photovoltaic projects can not adapt to east China power grid defense of uhv dc bipolar latching system frequency disturbance, east China branch of research put forward the east China area B class distributed photovoltaic involved network frequency technology requirements. Heat storage device file points out that the current east China network contains nearly 12 million kilowatts of distributed photovoltaic execution on net frequency technology standard is low, because of the large capacity in east China power grid main frequency of HVDC pole blocking caused wide fluctuations cases, could trigger a distributed photovoltaic large-scale network, intensifying power grid operation risk. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in project bidding and parity, the state-owned enterprises have become the absolute main force. Need to stress is that the cost of each province, the specific cost owing to the different provinces. Photovoltaic stents according to relevant personage, taking jiangsu province as an example, in general, access to distributed in 10 kv and the capacity of less than 5 mw photovoltaic power station power quality test can, just do general expenses in the 4 - 50000 yuan.
