摘要/Abstract

摘要： 为研究互联电网大停电的机理，提出了异质元胞自动机模型并将其用于模拟互联电网。首先，定义了元胞、同质邻居元胞、异质邻居元胞、元胞自动机模型、元胞自动机状态及故障传递规则；其次，将区域电网用元胞自动机进行模拟，并考虑不同区域电网之间的相互影响，建立了异质元胞自动机模型；随后，在电网受到大扰动和小扰动的情况下，利用异质元胞自动机模型对分区后的IEEE 118节点系统进行停电事故仿真，仿真结果表明各区域电网和整体电网大停电事故的标度-频度满足幂律分布，验证了此模型的可行性；最后，将异质元胞自动机模型与元胞自动机模型进行对比，并结合电网实际数据，结果表明此模型能更好地模拟互联电网大停电事故。

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
