The costs of real and reactive power are simple to include, and can be specified directly in the first and second ng rows of the gencost matrix. Rows ng+1 through 2*ng take the same form as rows 1 to ng, but are used to specify the coefficients for reactive power.
MATPOWER does not model FACTS devices directly, so I'm not sure how you plan to handle them. I suppose the SVC could be modeled as a reactive-only generator, but I'm not sure about the TCSC. Maybe two dummy reactive-only generators with additional linear constraints tying their injections together? -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Jan 26, 2013, at 9:24 AM, Khirad Dhabhar <[email protected]> wrote: > Dear all > > For my m-tech thesis i am using matpower.
