Abstract

Abstract: Based on current power receiving capability of Hunan power grid, difference between UHVDC and conventional unit is analyzed. Change of power receiving capability of Hunan power grid is calculated according to the latest network and load level during initial operation of UHVDC project from Jiuquan to Hunan. Impacts of different factors on power receiving capability of receiving-end power grid are compared, including load model, synchronous condenser, network modeling mode, power start-up mode, total load level, spinning reserve ratio and important sections power. The impacts on transmission capability of UHVDC project from Jiuquan to Hunan are discussed in detail. From the analysis, load model, synchronous condenser, network modeling mode and power start-up mode have larger impact than total load level, spinning reserve ratio and important sections power. The results offer references for testing and operation mode arrangement of UHVDC project from Jiuquan to Hunan.

Key words: UHVDC, receiving-end power grid, power receiving capability, sensitivity analysis
