Abstract

This paper firstly analyzes the uncertain factors driving the morphology evolution of distribution network from three aspects： policy, market and technology. Then, the system dynamics method is adopted to construct the power source structure evolution model of distribution network which considers multiple factors such as the growth rate of the installed capacity of new energy resources, further, the electric network topology evolution model is constructed with considering multiple factors such as the cost of grid structure and new energy accessing capability of distribution network topology. Finally, the relevant data of a certain province in the eastern coastal region is collected for simulation analysis. The simulation results show that the model proposed in this paper can both well reflect the proportion of new energy in the future distribution network, and predict the evolving direction of the future power grid topology.

Key words
