Distributed wind power is free and connected

Following the announcement at the end of last year of the availability of free network access for distributed photovoltaics, the State Grid now extends this special treatment to all types of distributed power sources. One of the most concerned is the distributed wind power. Experts in the industry have stated that obtaining distributed wind power projects that are free and well-connected with the Internet is expected to become a new opportunity for the continued development of wind power.

Yesterday, the State Grid issued the "Opinions on Doing a Good Job on Distributed Power Grid-connected Services," and distributed power generation projects with a voltage rating of 10 kilovolts and below and a single grid-connected point with a total installed capacity of no more than 6 megawatts are on-grid. Acceptance of applications, access system plan development, access system engineering design review, installation of metering devices, signing of contracts and agreements, grid acceptance and grid connection commissioning, government subsidy measurement and settlement services, no service fees are charged, and excess Electricity can be sold to the country.

On October 26 last year, the State Grid once said good to the photovoltaic industry and announced that it would receive distributed PV access for free. At present, it has accepted 119 distributed photovoltaic report installation services, generating capacity of 338,000 kW, and there have been reports of the first civil distributed photovoltaic power supply grid connection in Qingdao, Beijing and other places. The photovoltaic industry seems to have found it in a sad state. Twilight.

This time, the scope of support has been extended to solar, natural gas, biomass, wind, geothermal, ocean energy, and resource utilization. According to the “12th Five-Year Plan for Energy Development”, in 2015, China will build 1,000 natural gas distributed energy projects and 100 new energy demonstration cities based on distributed renewable energy applications. The scale of distributed solar power generation is Achieving 10 million kilowatts represents a great potential for distributed generation.

However, the development of distributed power supplies has been slow since the development costs are high and grid connection is difficult. “The national grid free service policy is exactly the right remedy for these two bottlenecks, thereby increasing the industry's development enthusiasm and bringing more users to participate in the development of new energy.” Li Qionghui, Director of the New Energy Research Institute, State Grid Energy Research Institute Indicated. The wind power equipment manufacturing companies that are in trouble now will also be saved.

It is worth noting that the distributed wind power project also enjoys the same special treatment as PV that does not charge system spare capacity. Therefore, some experts predict that, following PV, distributed wind power may become another major beneficiary of free policies. Popularly speaking, distributed wind power is a small wind power plant built in the courtyard of a household or in a factory. It is understood that China's distributed wind power resources are rich, coupled with the characteristics of the nearest access network, making it an important measure for cracking wind power development problems when large-scale wind power plants are in trouble. According to the plan, by the end of 2015, distributed wind power installed capacity will reach 30 million kilowatts.

However, at a time when large-scale wind power plants were in desperate need of relief, the country’s move to support distributed wind power was puzzling. Li Qionghui told reporters that it is not easy to solve the problems of large-scale wind power plants in a short period of time. Grid-connected technologies are not a problem, but due to the lag in grid planning, electricity cannot be delivered locally. As a result, distributed wind power dispersed throughout the area becomes a new choice.

In many of the optimistic moods, there is no lack of worry. "Unlike photovoltaic panels can be installed on rooftops, etc. Distributed wind power also requires approval of many links such as land and environmental protection. In addition, the cost of equipment is relatively higher. It can be seen that the development stage of distributed wind power has not yet achieved a breakthrough." A new energy expert said. In addition, Bai Jianhua, deputy chief economist of the National Grid Energy Research Institute, added that “distributed wind power is more random than large-scale wind power plants and its impact on the power grid is even greater. If grid-connected measures cannot be kept up to date, the future may The resulting wind-breaking phenomenon is more serious than that of a large wind power base."
