Micro-grids that are infrastructure for implementation and utilization of renewable energy sources require high-power-density, high-energy-density storage. Composite Energy Storage System (CESS) is a combination of various energy storage technologies that offers not only above performance but also high efficiency and long life. For system management of CESS, problems of energy management and dynamic control are questioned. In this paper, we propose the Energy Manager that support both short-term and long-term requirements of the CESS. Dynamic control of specific Dual-Active-Bridge (DAB) converters in order to provide compatibility with commands from Energy Manager is presented.
