Smart micro-grids offer a new and challenging application environment for modern power electronics. In fact, smart micro-grids are populated by a plethora of distributed energy resources (DERs), which interface with the distribution grid by means of electronic power processors (EPPs). This scenario enables the distributed control of the active and reactive currents flowing in the power lines, with...
This paper proposes a power management architecture that utilizes both supercapacitor cells and a lithium battery as energy storages for a photovoltaic (PV)-based wireless sensor network. The supercapacitor guarantees a longer lifetime in terms of charge cycles and has a large range of operating temperatures, but has the drawback of having low energy density and high cost. The lithium battery has...
Smart micro-grids offer a new and wide application domain for power electronics. In fact, every distributed energy resource (DER) includes an electronic power processor (EPP) to control the power exchange with the grid. If such distributed EPPs perform cooperatively, they have the capability to fully exploit all renewable power sources and energy storage units while improving the power quality and...
