Abstract :
This paper presents a cascaded H-bridge inverter topology for the application of secondary-use batteries as grid-connected energy storage. The proposed control strategy allows a degree of control over individual battery currents while the total system follows an arbitrary current command. This enables the aggregation and optimal use of battery packs with different capacities and states of health, overcoming a significant drawback of existing implementations.
