I am trying to modify the PSCAD simple solar farm example https://www.pscad.com/knowledge-base/...
into a Statcom. I hope to achieve statcom capability with the model. I have been able to get the model to work but I am now faced with a 2w ripple in the reactive and active power signal during fault. From my research, a DDSRF-PLL would address the ripple but I have not been able to make any progress using one obtained from PSCAD support.
Can you look into the results from this model (Q_POC during unbalanced fault) and recommend a solution.
