error - "There is no voltage source, current source, or machine block with a frequency matching the Phasor simulation frequency."

i am trying to connect a battery(NiMH, from simscape) across the capacitor of dfig(from simscape) in matlab simulink model. Voltage of capacitor is calculated outside and fed to battery's input (via a resistor) through controlled DC voltage source. but i am getting following error "There is no voltage source, current source, or machine block with a frequency matching the Phasor simulation frequency." please help urgently.
