Abstract:
1. A static security constrained automatic voltage control method, comprising: performing a single automatic voltage control calculation for a control snapshot of a power system at a beginning of a control cycle in each control cycle according to a requirement of a power grid operation for an automatic voltage control when on-line conducting at a power grid control center, wherein the single automatic voltage control calculation comprises steps of: (1′) obtaining a single-time severe contingency sequencing table and a periodical severe contingency sequencing table from a historical severe contingency information database, and selecting severe contingencies from a contingency set C (2′) solving a trial solution of an optimal power flow model, using the trial solution of the optimal power flow model as a base state of the power system, and performing an iteration between a first result of the contingency assessment for the active contingency set C (3′) performing a contingency assessment for the contingency set C
