Simulink toolbox to model pv array, battery, inverter, dc-dc converter, mppt, grid

Hi there,

I have to model a complete pv system which will charge a battery, the battery is connected to an inverter and the inverter either provides power to house or sends it back to the grid.

Now there are various toolboxes such as SimPowerSystems and SimElectronics to model these components. Which one do you think I should use to model all of the above components so they are all compatible with each other?

If your electrical system is multi-phase -- particularly three-phase -- then the answer is simple: use SimPowerSystems.

Otherwise, for single-phase systems, you can use either of the tools you mentioned.

• SimPowerSystems has more simplified (piecewise-linear) component models and is better suited for large system simulations where you can sacrifice some detail for simulation speed.
• SimElectronics has more detailed component models and can incorporate thermal effects. This is better for calculating losses, for example.

The examples that I have seen for PV systems controlled using MPPT have been with SimPowerSystems:

• http://www.mathworks.com/matlabcentral/fileexchange/34752-grid-connected-pv-array
