Research on power characteristics of high external power ratio power grid in market environment

This paper introduces the capability and requirements of the transmission grid structure of the receiving end network with high power proportion, and sorts out the positioning and planning ideas of the voltage level grid in the transmission grid structure of the receiving end network. Considering that the power load has a significant effect on the power receiving capacity in the power grid, an analysis method of the related characteristics of the power load is proposed. This paper summarizes the technical requirements of transmission network optimization and coordinated development at all levels, and applies them to the planning and optimization of transmission network frame, which effectively improves the power receiving capacity and safe and stable operation margin of the future power grid. Finally, the validity and feasibility of the proposed method are verified by the load characteristics of a real power network.
