Voltage control in an islanded microgrid

I am trying to design the outer voltage loop controller of the inverter but i am unable to remove the 5,7th harmonics from the capacitor voltage as i am trying to supply nonlinear load.

Hello Bijit,

there are numerous ways to address 5th and 7th harmonics. What strategy are you trying to use to solve the issue?

Here is a page discussing harmonics if you want to see some of the potential solutions. There are a lot and this list is not comprehensive: https://electrical-engineering-portal.com/principles-for-controlling-harmonics

Here are some basic resources for designing filters: https://www.mathworks.com/discovery/filter-design.html.
