"The "FixedStepDiscrete" solver cannot be used to simulate block diagram

Hey! I am facing the error "The "FixedStepDiscrete" solver cannot be used to simulate block diagram because it contains continuous states and i am doing the interfacing of battery with grid and using PI(Z) in converter design and don't know other continuous states that are used in the converter as the model is working fine without Battery.
