Modeling, Analysis, and Control of an Integrated Hybrid Energy Storage System

In traditional hybrid energy storage system (HESS), separated bidirectional dc/dc converter is usually used to interface energy storage system with dc bus. Though it has an advantage in flexibility of control system design using separated power converters, it results in more switches, auxiliary comp...
