Research and practice on coordination assessment system of Yunnan transmission network and power supply construction

Abstract

Power supply and power grid are both independent and closely related, and they are two parts of the power supply community. Power supply and power grid have their own characteristics and laws, and their interactions are different in different stages of development of power industry. Under the market environment of the new power system reform, some new changes have taken place in the relationship between the two. Firstly, this paper analyses the changes of the related factors of power construction after the reform of power system, and then constructs the coordination evaluation system of Yunnan power transmission network and power construction from the aspects of power development mode, energy policy and new energy access. Finally, taking Yunnan Province as an example, it evaluates the coordination of power transmission network and power construction in 2017, which proves the feasibility and science of the evaluation system.
