摘要:
According to the present situation of research, development and application of large-scale energy storage technologies as well as considering the regional features of energy resource distribution in China, the middle and long term development strategy of China and the pattern of"transmitting electric power from West China to East China, power exchange between South China and North China and nationwide interconnection of power grids in China", the development trend of energy storage technology are analyzed and discussed from the viewpoints of requirement, technology and economy. During the period of 11th Five Year Plan, the State Grid Corporation of China (SGCC) will research and develop the all-vanadium redox flow batteries with capacity in 100kW grade, the sodium sulpur batteries with capacity in megawatt grade, and the superconducting magnetic energy storage systems with capacity in megajoule grade that operates in temperature range of liquid-nitrogen;speed up the construction of mixed pumped storage power stations with capacity in 10GW grade to realize the optimized configuration of power grid;enhance the capability of power regulation, transmission and transformation to solve the trans-regional imbalance between supply and demand as well as to ensure the secure and reliable operation of power grid in China and to satisfy both requirement to power quality and development of renewable energy resources.
