Selection of optimal transmission voltage level/technology for the Saudi Arabian transmission grid

摘要: This paper reports the findings of a study aimed to investigate feasibility introducing AC-500 kV and AC-725 extra high voltage transmission expanding utilization 500/600 HVDC technology, for future bulk power between major areas on SEC network. The three alternatives were compared against present operating 380 kV. authors used planning bases criteria performing this study, which includes steady-state dynamic performance criteria, selection conductors different levels cost estimate elements economic parameters. Initially, technical analysis was conducted 2020, 2024, 2030 base cases validate whether existing new interties proposed by are sufficient achieve required transfer various areas. Further carried out determine shifting generation (thermal renewables) from COA EOA WOA. Once validity case scenarios investigated, techno-economic HVDC, AC 500 kV, and/or 725 studied years 2024 siting scenarios. These assumed displacements central area neighboring coastal In final analysis, allowed find most techno-economically viable option each scenario.
