摘　　要：基于Fisher判别方法和元胞自动机模型提出了一种微电网格局计算方法。建立了微电网元胞空间,运用Fisher判别方法获取微电网元胞空间的宏观演化规则,并根据微电网用户角色的多样化和电力交易决策的不确定性,制定了考虑领域关系的局部演化规则,提出了角色转化概率的概念。在Matlab环境下建立了仿真算例模拟微电网格局的时空动态演化过程。仿真结果验证了该方法对于微电网格局计算以及模拟微电网格局时空动态演化过程的可行性和有效性。Based on Fisher discriminant and cellular automata model an approach to calculate the configuration of micro-grid is proposed. The cell space of micro-grid is established and Fisher discriminant is utilized to obtain the macroscopic evolution rules for cell space of micro-grid. According to the diversity of micro-grid user＇s electricity demands and decision-making uncertainty of power transaction a local evolution rule considering neighbors＇ relationship is drafted, and a concept of role transition＇s probability is also proposed. Using Matlab, a model to simulate the time-space dynamic evolution process of micro-grid configuration is built. The availability and effectiveness of the proposed method in the calculation of micro-grid＇s configuration and in the simulation of timepace dynamic evolution process of micro-grid configuration are verified by simulation results.
