Assessing and mitigating problems associated with voltage security remains a critical concern for many power system operators. It is well understood that voltage stability, is driven by the balance of reactive power in a system. Of particular interest is to identify those areas in a system that may suffer reactive power deficiencies. Establishing the reactive power reserve requirements in these areas (VCAs), to ensure system integrity is of paramount importance. The approach is based on a Modal Analysis (MA) combined with Decision Trees (DTs). A database with user-friendly interface for storing/retrieving result of MA for each scenario was designed. The information in the database is used to construct DTs for each of the identified VCAs using key system attributes. In on-line application, the relevant attributes is extracted from a system snapshot and is dropped on DTs to determine which of the pre-determined VCAs can exist in the present system condition.
