Preventive security assessment

Here, the proposed attributes are elementary variables like power flows, EHV voltages, reactive reserves ..., and/or more sophisticated indicators like load power margins, describing the normal pre-disturbance state of the system. Such a state is classified as secure if the above mechanisms lead to acceptable post-contingency mid-term evolution with sufficient load power margin, otherwise insecure.
