I am trying to simulate a phasor domain model of grid connected wind generator. In this i want to add a battery bank and this battery will be supply power to a critical three phase load. Hence i need a battery and inverter in phasor domain.

The way phasor (or frequency and time in Simscape technology) are working is different to the time simulation. If, in a linear circuit, you are interested only in the changes in magnitude and phase of all voltages and currents when switches are closed or opened, you do not need to solve all differential equations (state-space model) resulting from the interaction of R, L, and C elements. You can instead solve a much simpler set of algebraic equations relating the voltage and current phasors. Phasors are complex numbers representing sinusoidal voltages and currents at a particular frequency. Therefore, it is not possible to use a switching device. Best to use an alternative implementation, at constant frequency, using supported blocks.
