Tricks:

• In the OpenDSS working directory, don't use any space in your folder's name.
• Sometimes, the order of your object properties matters. For example, New Load.1 kv=0.21 kw=1 kvar=1 model=1. Use the order manual provided.
• In Matlab interface structure, use *.get to check the structure fields. Or use VBA in excel to check, which is suggested by manual.
