Complex Network Characteristic of Power System Based on Energy Information in the Steady Transition Process

Abstracting the general concept of information and relative state of element, based on the structure and state research of complex network, this paper takes the branch potential energy as edge weight into the complex network modeling process of power system. It analyzes the physical meaning of element information and clarifies the physical meaning of the network parameters including steady energy in the status fluctuation. Simulation cases illustrate that, like topology distribution of structure and some power system state variables, certain of transition variables are proved to have typical complex network characteristics, such as scale feature and small-world, and a wide range of exponential and power-law distribution is found in the consumption process of disturbance energy in the power grid Such phenomenon and method can give a new perspective to research dynamic evolution of power system based on the steady energy distribution view in the steady transition process.
