Research on Optimal Construction Technologies for High-Proportion Receiving-End Transmission Power Systems

In this paper, satisfied abilities and requirements for construction of transmission grids in the high-proportion receiving-end power system are briefly introduced, to ensure safety operation in the power system. In the receiving-end power system, there exists key sections with significant impacts on outer-power receiving. Indices to precisely recognize these sections and strategies to enhance power-receiving abilities for these sections are proposed in the following. Technical requirements to optimized and coordinated develop all voltage levels of transmission grids in the high-proportion receiving-end power system are put forward according to the above analysis, and will be applied to plan future Jiangsu transmission power system. According to the research in this paper, the outer-power receiving abilities of future Jiangsu and even East-China power system will be improved, and margins for their security and stability will be enlarged.
