Recent studies have presented methods such as passivity-based stability criterion where the stability and other dynamiccharacteristics of an interconnected system can be effectively analyzed using bus-impedance measurement. Studies have presented online measurement techniques where the bus impedance is obtained by combining together the measurements of input and output impedances of single converters in the system.

Applying this method, all the impedances in the system can be simultaneously measured during one measurement cycle. Therefore, the overall measurement time of the bus impedance is reduced compared to conventional measurement techniques.
