The optimization of trans-regional electricity transmission scale of China’s Western renewable energy base is crucial to drive China's energy revolution. Currently, the regional power planning or optimization is aimed at minimizing the total economic cost, without taking the cost and benefit of transregional electricity transmission into account. In this paper, a regional planning model considering the cost and benefit of trans-regional electricity transmission was proposed, and the target of trans-regional electricity transmission scale by 2050 was optimized. This study analysed the influence of carbon price, fossil fuel scarcity value, accommodation cost for renewable power on the optimized result of trans-regional electricity transmission scale. Furthermore, the policy implication of the research was also analysed.
