( Industry news] 'Much starker choices-and graver consequences-in' to the intelligent power grid construction green grid development heibaocjp P Wire Show cable exhibition 】 Is the key to comprehensively deepen reform of the years, is the final year '12th five-year' plan, is also a 'much starker choices-and graver consequences-in planning. Recently, many heavyweight industry experts to 'much starker choices-and graver consequences-in power grid planning and puts forward personal opinions and Suggestions. ( Zhou Xiaoqian, former chief engineer of ministry of power industry) To advance and development of power grid. Grid is the carrier of electricity market, with the development of power market, the proportion of new energy, improve the supply side and users are put forward higher requirements of power grids, the country will also give more resources optimal allocation of grid task, these all require a grid more strong, greater transmission capacity, higher flexibility, informationization, intellectualized degree is higher. Therefore, the task of power grid construction and management of 'much starker choices-and graver consequences-in heavier, more demanding. To do this: A) First of all to the power grid more input, more assured on financing. Distribution of investment planning, to increase power grid investment ratio, appropriate grid investment to increase the proportion of distribution network. National investment to tilt to the grid. And to the power grid investment system reform, implementing diversification, absorb private capital investment. ( 2) 'much starker choices-and graver consequences-in' in the grid planning project schedule, the first to take the action plan in response to prevention and control of atmospheric pollution XiangJing beijing-tianjin-hebei lu, Yangtze river delta, the pearl river delta, such as heavy air pollution area of sending a channel for the construction of the arrangement. There are other such as southwest, northwest, northeast and other hydropower bases, base for coal and wind power and other new energy power generation for power transmission and transformation projects. Three is to strengthen the power grid structure, ability to accept outside sending in order to improve the power transmission and transformation projects, such as the need to build uhv ac network frame, east China power grid and north China power grid in order to improve the energy optimization configuration and accept ability, and proposed to build uhv ac network frame. In addition, to Tibet Tibet, sichuan power grid by the electric and three rivers upstream hydropower development planning. ( 3) Distribution network construction and retrofit is important aspect of the construction of the eccn 'much starker choices-and graver consequences-in planning. Generally weak current distribution network structure, the low level of automation, power supply reliability is low, it is difficult to adapt to large-scale new energy grid access and increase the need of demand side management, reform of the construction is not only including kv, kv power grid structure, power supply and the kv substation of dual ring net power supply, and the construction of informatization, automation, intelligent, to improve power supply reliability, improve system's ability to absorb all kinds of electric power, improve the utilization rate of distribution device, and reduce power transmission losses. ( 4) To further strengthen rural electric transformation, combined with the construction of new countryside to modify site including the county power grid construction. County power grid project has not been included in the scope of the rural electric reform of government investment, only rely on the power grid enterprise self-raised, caused by insufficient construction investment. ( 5) Attaches great importance to new energy sources such as wind power, photovoltaic power grid and the access of distributed power supply, micro power grid construction must be included in 'much starker choices-and graver consequences-in' power grid planning. ( 6) Through the planning and construction of the multinational network connectivity, so as to realize the optimal allocation of energy resources and the multinational to achieve the interconnection of results.
