一种用于无互连线逆变器并联的多环控制方法 针对传统逆变器无线并联系统稳态均流精度低和动态响应差等缺点，提出基于传统无 线并联下垂法的新型多环控制结构，分析了逆变器并联系统有功和无功功率的环流模型。( In this paper, a novel control scheme is presented, which is able to improve the transient response and power sharing accuracy of parallel-connected inverters with no control interconnections, and the active and reactive circulating current of the parallel system model are analyzed. A multiple-loop controller is developed based on the traditional droop method. )
