Overview of Microgrid
Series-type microgrid is a new type of microgrid system, and it is the vertical development of microgrid from the traditional single node in parallel to multi-nodes in series. As is shown in Fig. 1.5, each DG unit directly forms a microgrid system with a higher voltage level through the converter in series. This way of boosting voltage is not ...
