When applying Energy storage for PV system, ist it better to connect them on AC or DC bus?

From what I saw from other people's researches sometimes Battery is connected to DC bus using Bidirectional DC-DC converter. From DC bus power from battery and PV is connected tothe grid by going...

How does PWM contol Inverter that is connected to the grid? How do we decide the V refference?

I understand that when inverter change DC voltage(ex:PV voltage) to AC voltage, we need to condition the frequency and voltage to be the same level as the grid. We can use PWM for this. I study...

Is the $1000 VGA card worth to buy for MD and docking simulation ?

Our colleague suggests that, by bought the $1000 VGA card to our computer, our simulation would run incredibly faster, and can easily achieve 100 ns MD simulation in less than a week even though...

Can I use Thermodynamic Integration MD Simulation approach by using GROMACS?

So far we're using MD simulation to get RMSD result of the protein-ligand complex and see which one is the best. So far we didn't have the tutorial for doing Thermodynamic Integration MD...
