Hi Alexandra, The provision for entering cost functions in MATPOWER, 'gen cost' allows one to enter cost functions for both active and reactive power, however it distinguishes the two by hierarchy i.e. the first rows of cost functions are for active power, correspojding to the number of active generators you have defined. what follows are taken to represent reactive power. So if all you want is reactive power cost functions, i think you can enter zeros for the coefficients in the first rows equal to number of active generators and thereafter you enter the coefficients for the reactive power. Hope this can suffice
