Medium and Long-term Power System Development Planning Considering Carbon Dioxide Mitigation

The development of a low carbon economy and the consideration of carbon dioxide mitigation appear an effective solution towards the carbon emission goal in 2030. This paper proposes a medium and long-term power generation planning model considering the technology and policy factors with the accumulated total cost minimized. With the high proportion of renewable energy, this model adds carbon capture and storage technology and the carbon emission trade. A case study based on the future China national grid is provided to verify the proposed model. Results show that the carbon capture and storage technology and the carbon emission trade significantly reduce the carbon emission. Moreover, the utilization of renewable energy is raised, and the installed capacity and generation of fuel power plants are reduced.
