Power Grid Development Planning Based on Small World Model

Abstract

There are two main directions of the further development of power grid. One is the construction of higher voltage power grid. The other is strengthen power grid by keeping the original voltage grade. The current research of the two power grid directions focuses on comparing of specific project. The essence laws of power grid and its boundary conditions are less researched. In view of the above problems, this paper proposes a development simulation method of power grid based on small world evolution model. The method is based on the small world characteristics of power grid. And adaptability index for power grid are built. They can reflect adaptability of power grid to boundary conditions of essence laws. The grid development direction is established based on the adaptability index. It is fit to power grid situation and external environment. The simulation results of power system development show that proposed method is effective.
