Error in load conversion from Synergi - Power flow mismatch because of incorrect rated kVA #353

Open risjain opened 3 years ago

risjain commented 3 years ago

It seems that DiTTo is using connected kVA from Synergi to estimate the rated kVA of each load in the system.

However, it should use the regular kVA for load definition. Synergi uses connected kVA for load allocation, and therefore even if kVA of a section has no load, it may have non-zero connected load (think load carrying capacity).

This results in a severe load mismatch between the power flow solution between Synergi, and (in my case) the converted OpenDSS output.
