主 题：Sustainable energy energy saving power conversion solar PV system
摘 要：The Low Voltage Direct Current(LVDC)architecture gives higher benefits over the classic low-voltage alternating current(LVAC)supply *** has fewer energy conversion stages,is compatible with renewable energy sources,and is easier to integrate with *** this paper,an LVDC supply concept is proposed and compared with currently used conventional photovoltaic(PV)systems in terms of *** new LVDC photovoltaic system behavior is validated using LTspice modeling *** findings of this work prove that the concept of LVDC supply is highly attractive when the electricity produced by the photovoltaic is used onsite in the *** carry out an efficient system,the PV power mounted in the houses should be precisely rated with respect to the magnitude of the load energy *** proposed three house examples to verify the superiority of our proposed system in comparison with the traditional LVDC PV *** annual analysis of the energy saved by the studied systems was carried *** main benefit of the suggested LVDC supply is the short way taken by the energy generated by the photovoltaic system to supply DC loads within daytime *** registered increase in system efficiency reached more than 20%for the proposed LVDC system.
