Abstract

Abstract:

The decision of UHV AC or UHV DC transmission mode in bulk power system planning is a problem with the fast development of UHV transmission network. This paper focused on the application scope of UHV AC and UHV DC transmission distance based on the transmission capability. The evaluation indices were proposed for the AC and DC transmission mode, with considering AC and DC transmission characteristics, power transmission characteristics, security and stability, economic efficiency, etc. The models of 1 000 kV UHV AC and ±800 kV UHV DC transmission were estimated under ‘point to network’, by using optimal combination weigh method, and the application scopes of these two transmission modes were obtained. The proposed method and model can provide reference for UHV transmission network planning in the future, especially for the selection of power delivery mode for each large energy base.

Key words: optimal combination weighs, point to network, UHV AC, UHV DC, transmission application scope
