In conventional parallel hybrid energy storage systems (HESSs), there are usually two cascaded converters active when transferring energy between its energy storage systems (ESSs) that result in the overall efficiency drop. Moreover, the dc-link capacitor has to be oversized to limit the voltage ripple during simultaneous energy exchange between the ESSs and load feeding. The integrated reconfigurable...
When multilevel cascaded H-bridge converters are used to interface large-scale photovoltaic farms to the electricity grid, the stochastic variation of irradiance and other factors lead to unequal power generation among the phases, affecting the three-phase balanced system. Injections of fundamental frequency zero sequence to modulation references can deal with this problem. This paper proposes the...
