PERES Unit 5

The following is not a hybrid renewable energy system

• Solar+Wind

• WInd+Biomass

• Wind+Nuclear

• Solar+Biomass

The efficiency of a PV panel can be obtained from

• Form factor

• Fill factor

• Ripple factor

• Shading factor

Which of the following is not an advantage of hybrid system?

• Certainty of meeting load demand

• No need for power electronic converter

• Provides greater balance in energy supply

• Increased system efficiency

The issue in hybrid system is

• Requires battery which increases cost

• Load sharing between different sources

• A sudden change in the power output of one source affects stability

• All of the other options

The function of mode controller is

• To switch to the desired mode of generation

• Houses the microcomputer and software for source selection, battery management, and load-shedding strategy

• Monitors and controls battery state of charge

• All of the other options

The attached schematic shows a

• Wind+PV system with a common ac bus

• Wind+PV system with a common dc bus

• Wind+DG system with a common dc bus

• Wind+DG system with a common ac bus

The attached schematic shows a

• WInd+PV system with a common ac bus

• WInd+PV system with a common dc bus

• WInd+DG system with a common ac bus

• WInd+DG system with a common dc bus

In the attached schematic, the ac bus voltage is fixed by

• Wind system

• DG system

• PV system

• Grid

In the attached schematic, the dc bus voltage is fixed by

• Wind system

• PV system

• Grid

• Design

The dc-dc converter shown in the attached schematic helps to

• Reduce PV panel voltage to required bus voltage

• Helps to charge a battery

• Achieve MPPT

• Convert the dc voltage to grid voltage
