Zusammenfassung: | The invention provides an online prevention and control optimization method for static voltage stability of a power grid. The method comprises the steps: carrying out the static voltage stability evaluation of a PQ node, and determining the sensitivity relation of different regulation and control measures to the static voltage stability margin of the PQ node; evaluating the static voltage stability of the AC/DC interconnection node, and determining the sensitivity relationship of different regulation and control measures to the static voltage stability index of the interconnection node; establishing a prevention and control optimization model taking the minimum regulation and control cost as an objective function, and adding the constraint of the reactive power of the PV node into the prevention and control optimization model; screening regulation and control measures according to the prevention and control optimization model, judging whether a feasible solution meeting constraint conditions exists or not, an |
