| 摘 要： | 微电网孤网运行时的频率特性是微电网运行机理分析和控制策略研究的基础.针对逆变器、同步发电机和异步发电机不同接口型微电源,分别从控制策略、传递函数和结构特点等方面进行定性和定量分析,结果表明不同的微电源具有差调频、无差调频和无调频特性3种不同的调频作用.微电网的频率特性由不同微电源的调频特性共同决定,是否存在无差调频型微...

| Abstract: | The frequency characteristics of islanded microgrids are the basis for the feature analysis of microgrid,which is very important for the coordinated control of the microsources.Different power-frequency characteristics of the microsources are analyzed theoretically on the basis of the control algorithm,the transfer function and the structural features,which have different interfaces with the microgrid,such as inverters,synchronous generators and asynchronous generators.The analysis results show that differe... |
