Recently, the State Grid Corporation of Science and Technology Department of Intelligent Director Lin Hongyu at the Third China Smart Grid Construction and International Forum said that at present, China's smart grid has entered a phase of an all-round construction, while achievements, smart grid in the process of building Encountered some technical problems, the most prominent of which was the indirectness of new energy access to the power grid and the unbalanced trend presented. Promote power grid technology progress Starting from 2009, SGCC started the construction of a strong smart grid. It proposed that the construction of smart grid should be conducted in three phases: from 2009 to 2010, to regulate the pilot phase, from 2011 to 2015 for the full construction phase, and from 2015 to 2020 to the smart grid Construction optimization and upgrading. Subsequently, the State Grid Corporation of China prepared a smart grid key equipment demand planning, clearly defined what the key equipment is the focus of smart grid construction, put forward the direction of equipment development and goals. After the plan was launched, State Grid Corporation jointly developed the intelligent power grids in various fields, such as the smart grid dispatch support system, jointly with the Xidian Group, TBEA , ABB, General Motors and Siemens. Up to now, most equipment development has made good progress. Summing up achievements made by the smart grid in recent years, Lin Hongyu said that in order to ensure clean energy grid connection, SGCC has conducted a large number of pilot projects and has achieved very good technical results through engineering practice. In the field of clean energy grid, more unique is the Zhangjiakou Zhangbei region to carry out national scenery storage and transportation demonstration project. The first phase of the project construction of wind power 100,000 kilowatts, 40,000 kilowatts of photovoltaic power generation, storage batteries 20,000 kilowatts, supporting the construction of scenery storage and transportation joint control center and a 220 kV smart substation. Adopting a variety of wind power, photovoltaic and energy storage system of a variety of power generation combined mode, and using clean energy access to the grid intelligent optimization mode of operation. At present, the first phase of the project has been operating safely for more than 500 days with a total generating capacity of 370 million degrees. In addition, in the smart life of smart grid, State Grid Corporation since 2006, the electric vehicles, electric vehicles into the community on the distribution network, transmission network, and the impact of the operation and management of the study. With the development of family electric vehicles, fast charging and slow charging are also on the agenda. In response, the State Grid Corporation has developed a fast charge electric vehicles, slow charging charging pile, but also developed a battery replacement electric vehicles, but also the construction of a large number of electric vehicle charging station. Up to now, the State Grid Corporation has built 353 charging station, more than 14,000 charging pile. This reporter has learned that in the field of information collection system for electric power, State Grid Corporation started the construction of information collection system for electric power starting in 2008, focusing on the research and development of smart watthour meters and collection terminals, realizing the collection of electricity information through different networking modes, At the same time also established the provincial electricity information collection system, initially formed a collection of electricity information network. Up to now, the electricity information collection system has covered 25 provinces, covering 2.64 million users during the pilot period. Lin Hongyu said that the smart watt-hour meter can realize the transparent and open information and realize the two-way interactive service, which can support the implementation of the national price ladder. face the challenge Lin Hongyu also said at the same time, China's smart grid construction has made some achievements at the same time, there are also some shortcomings. He said that compared with other countries, China's clean energy access grid has shown an uneven situation. First of all, the clean energy grid-connected energy has been growing rapidly. The average annual grid-connected wind power generation has reached 74.9% over the past six years. At present, the grid-connected grid capacity has exceeded 60 million kilowatts. The national grid is already the largest in the world to receive wind power. 4.33 million kilowatts Second, the distribution of resources is quite uneven. A large amount of wind energy and solar energy are concentrated in the northwest and northeast regions. It is precisely these regions that are not the center of load. Load centers tend to be concentrated in the east, south and middle east. How to ensure the wind power grid and how to transmit it to the load center through long distance transmission make the application of clean energy facing a very urgent and severe test. In addition, wind and solar power are volatile, intermittent and random. To ensure the same output characteristics as conventional power supplies, many special techniques and special measures are required. Lin Hongyu stressed that with the development of distributed power grid and micro-grid construction, China's distribution network construction is also facing more and more serious challenges, the distribution network from a simple sale of power grid into an active grid, the corresponding Bring challenges in construction, management, operation and maintenance. He said that there is still a big gap between the distribution network in China and the international distribution network at the technical level. The traditional distribution network has low reliability, low automation and high power cut-off frequency. However, Lin Hongyu is still full of confidence in the development of the industry. He said that through the efforts of enterprises, it is still possible to realize the full automation of distribution network and reduce the number of blackouts and overhauls on a large scale so as to further raise the level of power supply reliability to the international advanced level. So, the development of clean energy and network integration is the most important measure? Chuck Adams, chairman of public affairs for the IEEE board of directors and a member of Huawei Enterprise Standards, has said it is imperative to combine large-scale energy storage technologies with increased predictability and balance. Energy storage will be able to provide the necessary reserves and balances. Transforming stored energy into grid transmission systems effectively and integrating decentralized stored renewable energy into a balanced infrastructure for people to use when they need it. Lin Hongyu believes that the current energy storage technology has been on the eve of an explosive development and revolutionary breakthroughs, we must follow real-time developments in international energy storage technology and the latest information, through research and engineering these new energy storage as soon as possible, in a timely manner Inspection and verification. According to reports, the State Grid Corporation of the next development goals are: in the power generation sector, to meet wind power installed capacity of 140 million kilowatts of wind power and other needs of the grid; in the transmission link, establish a monitoring link covering the whole power transmission and transformation equipment; Major cities to carry out distribution automation and distribution network repair command platform. At the same time, pilot applications of distributed power, energy storage and micro-grid access and coordination control will be carried out. In the electricity consumption segment, smart meter promotion will be vigorously promoted to speed up construction of information collection system for electricity use. It is estimated that the development goal of 500,000 electric vehicles will be achieved by the end of 2015. The charging and discharging network will meet the operational needs of 500,000 vehicles. In terms of dispatching, the dispatching system of the main grid and standby grid will be completed in the provincial and territorial plans.
