The purpose of this paper is to quickly and accurately perform the maximum power point tracking (MPPT) of a photovoltaic panel in accordance with the surrounding environment of variously changing photovoltaic systems. In this photovoltaic system, a power conversion system is configured with a differential power processing (DPP) structure to perform MPPT, and a method for improving this MPPT performance is proposed. MPPT is performed using the charging characteristics of the attached capacitor for voltage smoothing of the MPPT PV panel based on the proposed voltage reference model. The voltage reference model-based MPPT was applied to the proposed DPP structured photovoltaic system. Therefore, by enabling the expansion of the application of a high-efficiency photovoltaic system that has better power generation performance and can be adapted to various climate and temperature changes, a safer power generation system having less power loss was implemented to verify performance. It is also expected that by reducing the number of sensors in the system, annual maintenance costs will be reduced.
