Abstract

In this paper, phenomenon of islanding parallel inverters in an ac-distributed system is proposed. The paper explores the test results of the parallel-connected inverters in grid-connected system. The test results are devised and analyzed taking into account the power quality and the islanding performance. The islanding test methods applied. Experimental results are provided from two 2 kVA inverters connected in parallel, showing the features of islanding test.
