Abstract

DC bus voltage is used as the main control variable in many industrial power electronic devices for renewable energy applications with energy storage. However, when the dc voltage varies rapidly, the performances of the system can be affected. This paper presents theoretical analysis and experimental investigation of a hybrid grid-connected photovoltaic/wind energy system in which the dc bus voltage level is used to control the power exchange between the system´s components. The system´s operation was monitored for different operating modes (Float, Silent, Sell, Low battery transfer). The power transfer is analyzed and the performances are presented.
