Difficult to solve the bottleneck of grid-connected by renewable energy

Author: Li Guichen compared to the new energy industry revitalization Plan "Dystocia", the revised Renewable Energy Law in 2009 on the finale, a 2009-year new power drama painted a full stop. December 26, 2009, the NPC Standing Committee of the 12th meeting, the vote on the amendment of the People's Republic of China Renewable Energy Law (hereinafter referred to as the Renewable Energy Law) decision, through the formulation of renewable energy in the country to promote the development and utilization of long-term total goals of the relevant planning,　　The implementation of renewable energy generation full supportability purchase system, the establishment of renewable Energy Development Fund and so on.　　It is undoubtedly the most bright spot of the revised renewable Energy Law that the relationship between power grid enterprises and renewable energy grid-connected power generation interests and responsibilities is clear. "From the full purchase system to the present full guaranteed acquisition system, the grid enterprises to provide Internet service obligations, but also clear the corresponding economic compensation to solve the bottleneck of grid-connected."　　"This is the gospel of renewable power generation companies," said Jindomin, deputy director of the Renewable Energy Development Center at the NDRC's Institute of Power.　　However, in the face of such institutional arrangements, power grid enterprises have something to say. "The Renewable Energy Law mentions the development and application of smart grid technology to improve the capacity to absorb renewable energy, but there is still no overall endorsement of the strong unified smart grid concept we have put forward."　　"The concern of Zhaoguang, deputy dean of the National Grid Energy Research Institute, is that the smart grid, as a solution to grid-connected renewable energy power, is still short of policy."　　It is understood that the power grid to accept renewable energy power will be through the local elimination, regional power grid within the elimination, long-distance transport + smart grid three technical process. "With the unprecedented development of renewable energy, less prominent three years ago, the problem of grid-connected has become the biggest obstacle to renewable energy generation." "In the China International Smart Grid Industry Forum," Wang Jingli, a researcher at the National Development and Reform Commission Energy Research Institute, said that wind power, as an example, according to the national "building a large base, into the big grid," The wind power planning concept, in a few years, our regional grid, such as the Northeast and northwest, has been unable to solve such large-scale internet　　According to the National Grid Energy Research Institute of the calculation, if the 2020 wind power installed Capacity planning to upgrade to 150 million kilowatts, no smart grid, the grid can only eliminate the planning of 50%-60%, the need for long-distance transport and smart grid mode to solve. May 2009, the state Grid company put forward the idea of building a unified strong smart grid, will soon build a special high-voltage grid as the backbone of the network, the coordinated development of all levels of power grids unified strong smart grid. According to the author, at present, the State Grid company is to unify the strong smart grid such a strategic concept into the development of power grid planning, the preparation of Twelve-Five power grid development planning. "If the country can promote strong smart grid construction to the national strategic level, the introduction of relevant policies and regulations, to provide financial support for our strong smart grid construction will be critical."　　"Zhaoguang said. However, the amendmentAfter the "Renewable energy Law" does not seem to provide adequate policy assistance to smart grid construction, in the full guarantee of the implementation of the purchase system, the purchase of electricity in the proportion of renewable energy consumption, renewable energy generation of grid-connected national standards for the formulation of the issue of different degrees of "white". The revision of the Renewable Energy Law is a guide that will lead to the study of the implementation details.　　Jindomin said that the next step of the national Development and Reform Commission and the IPCC will jointly develop security grid access to the implementation of renewable energy regulations, renewable energy generation of grid-connected national standards will also be put on the agenda.　　However, for the establishment of grid-connected national standards, renewable energy generation Enterprises also have their own views. It is understood that the State grid prior to the "State Grid company wind farm access to the power grid technical provisions" is considered to be the grid enterprises set up the internal grid standards, "this is actually in raising the threshold to restrict access to renewable energy generation." "This approach is putting the cart before the horse," said the chief engineer of a renewable power generation enterprise. "China's wind power generation capacity has reached the fourth in the world, while the country has 1/3 of the wind power network is not smooth." In this case, the grid enterprises have to assume their responsibility, from improving their ability to eliminate the capacity to fully guarantee the access to renewable energy generation, rather than set the technical threshold again, to stop the electricity outside the grid. "Obviously, with the development of the national standard of renewable energy grid, the new game of responsibility between renewable power generation enterprises and grid enterprises will be inevitable."
