微电网中太阳能分布式发电的建模与仿真

分布式电源是智能电网一个重要的特征.阐述了微电网的定义及太阳能分布式发电工作原理,考虑光照强度等环境因素的变化,建立光伏发电的数学模型.利用Matlab软件中的Matpower软件包对接有太阳能光伏分布式发电的IEEE34配电系统进行随机潮流计算,观察潮流分布状态.仿真分析表明,分布式电源的接入对系统有积极作用,能减少系统线路损耗.;Distributed power is an important feature of smart grids. The definition of micro-grid and the operating principle of solar distributed generation are described. Considering the changes of such environmental factors as light intensity，a mathematical model of photovoltaic power generation is established. Matpower of Matlab software is applied in calculating the IEEE34 distribution system with photovoltaic power generation，and observing trend of the flow distribution，and the simulation shows a positive effect with a distributed power system，and less line losses
