Stability analysis of distributed power generation system becomes complex when there are many numbers of grid inverters in the system. In order to analyze system stability, the overall network impedance will be lumped and needs to be analyzed one by one. However, using a unified bulky transfer-function creates an ambiguity of knowing the reason of instability and also there is no fixed way of choosing the sequence of the analysis. This paper suggests a method to perform a regional stability… CONTINUE READING
