Research on power supply planning in power market

In power supply planning, power supply planning with sustainable development has been paid more and more attention. Considering economy, science and technology, environment and other fields comprehensively, this paper analyzes the evaluation index of sustainable development of power supply planning, and establishes a decision-making model of multi-objective power supply planning considering sustainable development. The model can be divided into different subsets according to the characteristics of factor variables such as target variables and attribute variables, and the complexity of the planning model can be reduced based on the logical relationship between different nodes. It points out that the modeling of new problems, the coordination of multi-investors, the establishment of power supply planning mechanism and post-evaluation system are the emphases of the research.
