“…As the load grows, generators reach their operational limits that, in turn, prevent them to contribute further with the EPS. During static voltage stability analysis, interest lies in constraints that limit the reactive power supplied by generating units, since they are capable to reduce significantly the MLP and even drive instability (YORINO; LI; SASAKI, 2005; CAO; CHEN, 2010;CHIANG et al, 1995;AJJARAPU, 2007;CHAKRABARTI, 1996).…”
