integration of PV system and battery with single phase power grid ( using PSIM software) -- 3

I am doing my project on integration of PV system and battery with single phase power grid . I have already designed the converters with controllers (dc/dc boost converter on PV side, dc/dc bidirectional buck- boost converter and dc /ac converter with PLL on grid side ). So i still need to integrate all converters with power management control ( i want the system to charge the battery when the PV generate power more than the power required to the grid , and discharge the battery to supply the grid PV when the PV doesn't generate enough power as required to grid).
