Dear Dr Ray, Allow me to restructure my question. So you only need to refer to this email and not the earlier ones.
I am trying to model variable reactance in series of a line which acts like TCSC (A series FACTS device) Its working behaviour is simply govern by such inequality constraints: Xmin <= Xtcsc <= Xmax In effect, I am expecting matpower to use newton rahpson method ( or any other iteration method ) to solve the value of Xtcsc which will add with line reactance as the TCSC and line is connected in series. My question is how can I add the additional inequality constraints: Xmin <= Xtcsc <= Xmax in MATPOWER? I have read the manual several times, but I cannot get the idea. Please help.
