Renewable energy sources are becoming more attractive due to their eco-friendly nature. As conventional energy sources are polluting environment, it has become imperative to shift to renewable energies. PV and wind are popular renewable sources because of their abundance availability and cost effectiveness. But, renewable do not being able to supply continuous power owe to intermittency of renewable sources. This issue can be addressed by efficiently integrating battery with renewable sources. The usual approach for this is to use dedicated single-input converters one for each source. In this, the sources are connected to a common dc bus. The special converters which are used for the integration purpose would not work properly due to renewable intermittency. The efficiency of integrated system would be decreased due to multiple power conversion stages. So, the major challenge is to decrease power conversion stages and hence losses of hybrid system. A control technique has been proposed in this work for tracking Maximum Power Point (MPP) of both wind turbine and photovoltaic array through adjusting the duty cycle ratios of switches used in converters under varying climatic conditions.

Abstract


Renewable energy sources are becoming more attractive due to their eco-friendly nature. As conventional energy sources are polluting environment, it has become imperative to shift to renewable energies. PV and wind are popular renewable sources because of their abundance availability and cost effectiveness. But, renewable do not being able to supply continuous power owe to intermittency of renewable sources. This issue can be addressed by efficiently integrating battery with renewable sources. The usual approach for this is to use dedicated single-input converters one for each source. In this, the sources are connected to a common dc bus. The special converters which are used for the integration purpose would not work properly due to renewable intermittency. The efficiency of integrated system would be decreased due to multiple power conversion stages. So, the major challenge is to decrease power conversion stages and hence losses of hybrid system. A control technique has been proposed in this work for tracking Maximum Power Point (MPP) of both wind turbine and photovoltaic array through adjusting the duty cycle ratios of switches used in converters under varying climatic conditions.
