reactive power control by Genetic Algorithm

I have a very small project.I have a load flow code with output as volt. profile.U just have to bring that volt. profile within a given limit by controlling the reactive power of dg,reac when position of dg and reactor are fixed . I have a GA code.U just have to make some chages in [login to view URL] code gives best location of DG.I want location fixed and reactive power as outpu
