I have modeled multi machine-9 bus system and tried to configure DSTATCOM with it, but couldn't able to compensate the demand of reactive power of the load of (10 MW + 40 MVAR). Actually, The quadrature and reference quadrature current are coming out of phase to eachother. The DC voltage is increasingly continuously. The system bus voltage is 230 kV, DC capacitor is chose to be 10000 micro farad and DC reference voltage is taken to be 2500 V. Sample time taken for 5 micro seconds. Please suggest me , is there anything I have to change with tuning of PI controller of regulators gains. I have used per unit system , with base of 100 MVA and 230 kV.

Unfortunately, you do not provide enough information to provide any guidance. Did you start with a 9 bus system. You should try to get something similar working in a smaller system first. If you have issues with that simpler system, you can share your model and ask more specific questions. There is no way to know what you need based on the information that you have provided.
