I am unable to upload image here. It is 4 LV (0.66 KV) and 1 HV (33KV) transformer. LV side is connected to either solar inverter or BESS PCS. 33 KV Side will be connected to HT panel. In India 5 winding transformers in solar and BESS are used. However, PSS/E only has 2 wdg and 3 wdg transformers. It is possible to model using multiple of 2 or 3 wdg transformers. But in that case, will the final results will be impacted or what can be better modeling practice? In multiple transformer model, splitting of impedance is important, which is generally not specified in datasheet. Insite in 5 wdg transformer modeling will be much helpful. Thank you in advance.
