Static security constrained automatic voltage control method

摘要

A static security constrained automatic voltage control method is provided, which includes: performing a single automatic voltage control calculation for a control snapshot of a power system in each control cycle. The single automatic voltage control calculation comprises: 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; performing a contingency assessment for the active contingency set, and iterating between a result of the contingency assessment for the active contingency set and a solution of the optimal power flow model to obtain a single automatic voltage control instruction; and performing a contingency assessment for a contingency set, and updating the single-time severe contingency sequencing table and the periodical severe contingency sequencing table according to a comprehensive result of the contingency assessment.
