Active Distribution Network Bifurcation and Voltage Stability Research

It analyzes the common bifurcation categories in active distribution network; based on the active distribution network's wind field system model, it changes the reactive power parameters of its load model and conducts studies on the influence brought by reactive power on voltage stability based on bifurcation theory; it calculates Hopf Bifurcation Point in the wind power system containing SVC; it judges Hopf Bifurcation based on parsing algorithm; it analyzes the influence brought by reactive power and VC on wind power system. The result indicates that the increase of reactive power in wind power system will create Hopf Bifurcation in the system and it will use SVC to conduct reactive compensation, by which it will delay Hopf Bifurcation and elevate the active distribution network's voltage stability.bifurcation theory, active distribution network, voltage stability
