How does the PV with variable output voltage connect to the dc bus with constant voltage?

We all know the MPPT controller of PV adjusts the output voltage to satisfy it's requirement of maximum output power. We also know the PV connects to the dc bus directly.However,we certainly want the dc bus voltage to keep at a constant value,that's the question,how can we connect a variable output to a constant dc bus?

"We all know..." - Do we? I do neither know, what a "MPPT" controller is or what "PV" means. Are you working with Simulink?

[Lu Z]

emmmm....This subject is about electric engineering.PV means photovoltaic while MPPT means Maximum Power Point Tracking.If you're not major in this,I don't know how to explain it.

@Lu Zicong: Most like it is not required to explain these details at all, because Matlab is not an engineer also. I assume your question concerns Matlab or Simulink, but you did not specify this yet.

As far as I'm concerned,if you can understand my title,you must know which my question concerns.If you do not understand,it means you do not know about dc microgrid,not to mention MPPT or in-depth details,you can not solve it.So，what else can you do even if you know my question concerns Matlab or Simulink?On the other hand,my focus is not in matlab or simulink,it means,if I solve my question,I can choose matlab to achieve, but also can choose simulink.

I asked for the relation to Matlab or Simulink, because without such a relation, the question would be off-topic and closed.

While it is clear, that I cannot help you to solve your problem, I can encourage you to formulate the question such, that more readers can understand it. This increases your chance to get a useful answer. Please read this.

Good luck!

I am having almost same problem as you do. How have you solved your's? Can you help me?

[Albasheri Mohammed]

you can use the energy storge system as battery or supercapacitor to keep it constant

Yes it is possible
