| dc.description.abstract | With increasing the penetration of renewable energy sources and energy storage devices in the power grid, and according to the recent fast-growing trends in electrification of the transportation in land, sea and air vehicles, power electronics converters are becoming one of the dominate parts of the power grids and vehicular power systems. In a power electronics rich power system, there are several power electronics converters that send and receive power bidirectionally and interact with each other. Because of the interactions between power electronics converters, and the need for transferring power bidirectionally, power flow management in smart grids and vehicular power systems is challenging and, in some cases, impossible using conventional power distribution systems. In this research, a novel power distribution system is introduced, which creates the possibility of adding virtual frequency channels to the power system each one of these channels is inherently isolated. The frequency channels will not interfere with each other due to orthogonality of the waveforms, and because of that, power can be transferred between every combination of the sources and loads without interfering others through isolated frequency channels. This power distribution system is based on a multi-frequency multi-port power conversion system in which power is integrated at various frequencies at the source ends and selectively picked up by the loads, or vice versa. In this research, after introducing multiport power conversion systems and their challenges, the concept of the multifrequency power transfer will be investigated, and finally, the realization and implementation of the multi-frequency multiport power conversion systems will be discussed. The proof-of-concept will be validated both by both simulation and experiment. | |
