Constants and variables in the model.

Symbol	Data type	Variable type	Dimension	Description
𝑛	Number	Constant	1	Transformer number
𝑅	Vector	Constant	𝑛×1	Transformer capacity
				𝑅𝑖 is capacity of the ith transformer
𝑇	Vector	State variable	𝑛×1	Transformer loading factor
				𝑇𝑖 is loading factor of the ith transformer
Tr	Matrix	Free variable	𝑛×𝑛	Load transfer capacity
				Tr𝑖,𝑗 is the load transfer capacity from the ith transformer to the jth transformer when the ith transformer fails
