Probabilistic Security Assessment for Power System Operations Conference Paper uri icon

abstract

  • Control room operators are faced with frequent security-economy decision-making situations necessitated by stressed system operating conditions, and there is increased need for security-economy decision-support tools. Although probabilistic methods are promising in this regard, they have been mainly used in planning environments. This task force paper explores their use for operational decision-making, comparing them to the more traditional deterministic approach. Two examples are used to facilitate this comparison via overload and low voltage security assessment to identify secure regions of operation for a small 5-bus system and for the IEEE Reliability Test System. The results of this comparison show that the probabilistic approach offers several inherent advantages.
