I would just caution you that, just because you find a case file with a particular set of cost coefficients does not mean that those cost coefficients are in any sense "typical" generator costs. In many cases, they are more likely some random numbers that someone typed in so they could run an OPF.

Specifically, the generation cost is like this: f=a*P^2+b*P+c, where the P is the active power output. The coefficients are a,b,c. For the Var devices cost, I hope the cost is composed by f=C_fix+C_variable*Qc, where Qc is the output reative power of the Var device. And the coefficients are C_fix and C_variable. Does anybody have some reference data please? Thank you so much.
