Developing Cooperation among Provcinces in Electric Power and Improving Capability of Trans-regional Power Transmission

Based on the characteristics of energy resource distribution and economic development of China,it is a dominating trend to enhance cooperation in electric power among different provinces and increase the volume of power transmission among regional power grids.In order to solve the problem of lack of energy resources in Jiangsu province during its rapid economic development and take the advantage of the Shanxi province as an energy base,it's an important means to speed up trans-regional grid construction and reinforce transmission between regions.This paper analyzes the status of the power market in Jiangsu and power plant construction in southeast of Shanxi at the end of the "11th Five-Year Plan",and it proves the feasibility of transmitting more power to Jiangsu around the 2010.By comparing the efficiency and technology of a number of scenario,the scenario of ±500 kV HVDC transmission is recommended.
