Power system electromagnetic transient (EMT) simulation has been used to study the electromagnetic behavior of power system components. It generally comprises detailed models of the study area and an equivalent circuit which represents an external part of the study area. However, a detailed description of an external system that includes transmission or(More)
This paper proposes a distributed control strategy that considers several source characteristics to achieve reliable and efficient operation of a hybrid ac/dc microgrid. The proposed control strategy has a two-level structure. The primary control layer is based on an adaptive droop method, which allows local controllers to operate autonomously and flexibly(More)
This paper describes a new digital current sharing method for parallel interleaved dc-dc converters. The difference between sensed inductor current values can cause unequal current distribution in the parallel dc-dc converters even though they are controlled by the same average current mode controller with a common current reference. To overcome this(More)
