Integrated Routing Architecture and Efficiency Optimization Based on Partial Power Conversion

Application of clean energy, such as photovoltaic (PV) and hydrogen energy with high efficiency has become a trend in recent years for the global energy system. This paper established a partial power conversion (PPC) based energy router (ER) scheme for the distributed energy by considering the efficiency and characteristics of PV cell, reversible solid oxide cell (rSOC) and battery. There are three DC buses in this ER, each PPC port is isolated by a quad active bridges (QAB) converter, then the system topology decoupling mechanism and parameter optimization are carried out. A typical operation mode is analyzed as an example of eight scenarios of the ER system, and then the corresponding energy control strategy is given to achieve high efficient power transmission. The viability and effectiveness of the suggested system are verified by simulation and experimentations.
