Abstract

Abstract: In order to study the mechanism of large blackouts of interconnected power system, a heterogeneous cellular automata model is proposed and used to simulate interconnected power system. Firstly, cells, homogeneous neighbor cells, heterogeneous neighbor cells, cellular automata model, the state of cellular automata and fault transmission rules are defined. And then, the cellular automaton is used to simulate regional power grids with consideration of the mutual impacts of different regional power grids, and a heterogeneous cellular automaton model is set up. Subsequently, the heterogeneous cellular automata model is used to simulate the blackouts of a partitioned IEEE 118-bus system under the large and small disturbances. The simulation results show that the scale-frequency of blackouts in the entire power grid and each regional power grid follow the power-law distribution, verifying the feasibility of this model. Finally, the heterogeneous cellular automata model is compared with a cellular automata model, and operated with the actual data of power system, and the results show that this model can better simulate blackouts of interconnected power system.

Key words: interconnected power system, heterogeneous cellular automata, self-organized criticality, large blackouts, partition
