How do I simulate weak grids for on-grid inverters?
I am currently simulating an on-grid three-level NPC inverter, and I would like to verify my controller under weak grid conditions, the questions are:
Which block should I use to simulate weak grid conditions?
Are there any specific blocks or methods to specifically add more harmonic distortion to specific harmonics? For example, my controller is based on PR controller and is able to attenuate the 3rd, 5th and 7th harmonic. I want to simulate an increase the grid distrubance on the 3rd harmonic, so i can test out the PR’s capabilities.
Anybody who is familiar with this simulation or topic, please provide some help, I would be very thankful!
