“…As a result, the whole system can be viewed as a single power processing stage that has multiple interfacing ports. In these systems, input power sources are usually connected to a high-frequency AC link, and isolation transformer plus AC/DC/AC interfacing converters are utilized to connect the generation into the load/grid [16]- [20].

Today, conventional power systems are evolving to modern smart grids, where interconnected microgrids may dominate the distribution system with high penetration of renewable energy and energy storage systems. The hybrid AC/DC systems with DC and AC sources/loads are considered to be the most possible future distribution or even transmission structures. For such hybrid AC/DC microgrids, power management strategies are one of the most critical operation aspects. This paper presents an overview of power management strategies for a hybrid AC/DC microgrid system, which includes different system structures (AC-coupled, DC-coupled, and AC-DC-coupled hybrid microgrids), different operation modes, a thorough study of various power management and control schemes in both steady state and transient conditions, and examples of power management and control strategies. Finally, discussion and recommendations of power management strategies for the further research are presented.

The paper gives an overview of the innovative field of hybrid energy storage systems (HESS). An HESS is characterized by a beneficial coupling of two or more energy storage technologies with supplementary operating characteristics (such as energy and power density, self-discharge rate, efficiency, life-time, etc.). The paper briefly discusses typical HESS-applications, energy storage coupling architectures, basic energy management concepts and a principle approach for the power flow decomposition based on peak shaving and double low-pass filtering. Four HESS-configurations, suitable for the application in decentralized PVsystems: a) power-to-heat/battery, b) power-to-heat/battery/hydrogen, c) supercap/battery and d) battery/battery, are briefly discussed. The paper ends with a short description of the HESS-experimental test-bed at Chemnitz University of Technology.

“…For connecting multiple sources and storage either multiple converters or an integrated multiport converter can be used. An integrated multiport converter proved to be more efficient than the multiple converter structure because of its simplified structure and centralized control [4,5,6,7]. Recently various topologies of multiport converters have been reported in the literature because of their increasing merits.…”

In this paper, an integrated four port DC-DC converter with bidirectional power transfer capability is proposed for connecting two photovoltaic sources with an energy storage element to a dc load. This converter achieves high power density due to its integrated structure and device sharing feature among the ports. Adopted PWM and secondary side phase-shifting control eliminates the circulating current and its associated conduction losses and minimizes the current ripple at input ports. Further, it simplifies the complexity of control by decoupling the control variables of input and output ports. Working of the converter under different operating conditions are verified with a 500-W experimental prototype.
