Available Transfer Capacity calculation based on carbon emission reduction strategy

Increasingly serious issue of climate change proposed an urgent requirement of low-carbon development on the global challenges. The power industry mainly contributes to CO₂ emissions. Available Transfer Capacity (ATC) reflects power generation, transmission, distribution, supply and demand situation in electricity transaction. In order to improve the energy efficiency of the power industry and promote carbon emission reduction, this article proposes a calculation method of ATC with minimum unit carbon emissions and fuel costs, considering the security, economic and environmental factors. It aims to reasonably schedule inter-regional resources and makes full use of the transfer capacity of the existing equipment. The results have shown that carbon emissions and ATC has a certain contradiction with each other and could not be optimal simultaneously. Sacrifice of a certain amount of ATC was needed to control the carbon emissions. The method proposed in the current imbalance state between economic development and environmental protection accords with the global carbon emission reduction targets and energy strategies for sustainable development.
