35 Personal Advice 1. Significance of Smart Grid Development

 Smart grid is an important platform for the implementation of new energy strategy and energy resource allocation optimization, covering power generation, transmission, substation, power distribution, utilization and scheduling of each link.  By the extensive use of advanced information and materials technology, the large-scale access and utilization of clean energy can be realized, while the energy utilization efficiency can be improved, ensuring the safe, reliable and high quality power supply.  It is of great significance to adjust the energy structure in China, to address climate change and to realize the energy conservation and emissions reduction, as we implement the smart grid major industrialization projects of science and technology.

2. Smart Grid Development around the World  United States: Smart grid plans focus on distribution network. To improve the efficiency of electricity side, to reduce the electricity cost and to improve the grid security;  EU: Super smart grid plans take the distributed power supply and large-scale use of renewable energy as the main target, while attention are paid to improve and enhance energy efficiency. Britain, France, Germany and other countries focus on development of pan-european network interconnection, Italy focuses on smart meter development and distribution network interaction, while Denmark is focus on wind power generation development and its control technology;  Canada: Focus on the access ability and transmission ability enhancement of grid to large-scale renewable energy;  Japan: The core of smart grid construction is to develop a grid which can be adapted to the scale development of solar power;  Korea: Smart grid research focus on smart green city construction, while a comprehensive smart city demonstration project is now being constructed in Jeju island.  Australia: The goal of smart grid construction is to develop renewable energy sources and improve energy use efficiency. The main work is focus on the implementation of smart meter and its associated demand side management.

2. Smart Grid Development around the World

 In conclusion, the concern of smart grid focus on: . Large-scale access of renewable energy power generation technology and its associated with large-scale energy storage operation; . Large power grid interconnection, long distance transmission and related control technology; . Distribution automation and micro-grid; . Smart meter of user side and demand response technologies.

3.Smart Grid Development in China

 In March 2011, the "the twelfth five-year plan for national economic and social development outline” was released, putting forward the overall task of the electric power industry transformation and industry core competitiveness enhancement during the " twelfth five-year “: . Accelerate the construction of modern power grid system in demand of the requirements for large-scale interregional transmission and new energy grid-connected. . Further expand the scale of "west to east electricity transmission“, improve the regional backbone grid by developing the large capacity, high efficiency and long distance transmission technology such as ultra-high voltage. . Push forward the construction of smart grid by advanced technologies such as information, control and energy storage. . Strengthen the construction and upgrading of urban and rural power grid, enhance the capacity of grid electricity optimal allocation and power supply reliability.

3.Smart Grid Development in China

 This is based on two facts:

. One is lack of energy resources per capita, and the energy resources and demand distribution is extremely unbalanced on the geographical distribution; . the other is the stress of electric power system development deal with climate change. It is imperative to improve power system security and efficiency, and replace coal with all sorts of new energy and renewable energy in order to adapt to the energy demand and climate change.  Moreover, the technical problems of grid-connected and consumption brought by the intensive development of intermittent renewable energy generation are far more than the developed countries and regions.

3.Smart Grid Development in China

 Strong smart grid: In 2009, the State Grid Corporation of China formally issued the “Construction of strong smart grid”, publishing the ”smart grid” development plan to the society. China smart grid is first a strong power grid, which among them, has a long distance, large capacity transmission ultra-high voltage grid as its core link.  Three phases were put forward to promote the construction of the “strong smart grid” : . the planning pilot stage before 2010; . the overall construction stage from 2011 to 2015; . the upgrad stage from 2016 to 2020.  In 2011, the State Grid Corporation of China formally issued the “Smart grid technical standard system planning“ and “Key equipment for smart grid development planning “.

4. How to Focus on Smart Grid Development of Sino-US Cooperation

2012.11.6, Sino-US smart grid meeting was held in Guangzhou, some Chinese experts put forward opinions on how to promote the cooperation, mainly as follows:

 Sino-US electric power system and changing trends . China electric power system evolution, factory network separation, etc . American electric power system evolution and its reference function  Sino-US smart grid technology, industry and demonstration comparison . Smart grid technology industrial development . Smart grid cooperation in the field of intellectual property  Sino-US smart grid investment and profit analysis comparison . A specific technical analysis of its investments and profits in the whole operation of smart grid, such as smart meters . Comparing the smart grid investment and profit in China and US  Sino-US smart grid cooperation and communication platform; Key technical cooperation; Demonstration area cooperation, etc. . Key technology . Demonstration area 5. Personal Advice

 To find demonstration areas in both China and US, make the comparison on their technique, industrial cooperation, cost and benefit analysis, and put forward policy suggestions  Hope that there will be breakthrough and progress on . large-scale intermittent new energy grid technology . grid technology in supporting electric vehicles development . large-scale energy storage systems . large power grid intelligent operation and control . intelligent power transmission and transformation technology and equipment . grid information and communication technology . flexible transmission technology and equipment . smart grid integration comprehensive demonstrations Thank You!
