| titleOfInvention | An online preventive control optimization method for grid static voltage stability |
| abstract | The invention provides an online prevention and control optimization method for the static voltage stability of the power grid, which evaluates the static voltage stability of the PQ node, determines the sensitivity relationship of different control measures to the static voltage stability margin of the PQ node, and evaluates the static voltage stability of the AC-DC interconnection node, Determine the sensitivity relationship of different control measures to the static voltage stability index of interconnected nodes; establish a preventive control optimization model with the minimum control cost as the objective function, and add the constraints of PV node reactive power to the preventive control optimization model; according to the preventive control optimization model , carry out the screening of control measures, and judge whether there is a feasible solution that satisfies the constraint conditions. If there is, the feasible solution is a preventive control measure; if not, relax the constraint conditions and continue the screening of control measures until there is a feasible solution. The processing speed of the present invention is faster and more reliable, and better satisfies the real-time performance. |
