Risk Assessment of Rare Events in Probabilistic Power Flow via Hybrid Multi-Surrogate Method

Processing Events in Probabilistic Risk Assessment

Assessing entity (e.g., person) risk from entity-related events requires appropriate techniques to address the relevance of events (individually and/or in aggregate) relative to a prevailing temporal frame of reference—for continuous risk monitoring, a running time point representing “the present.” We describe two classes of temporal relevance techniques we have used towards insider threat dete...

Voltage Stability Assessment via Continuation Power Flow Method

1 Abstract — This paper presents a potential algorithm for continuation power flow method in voltage stability assessment. Modified continuation power flow method termed as MCBF was developed which solved the solution of bifurcation point at the Q-V curve. The solvability of power flow at the bifurcation point beyond the maximum loadability point of a system was achieved through the implementat...

Hybrid Method for Optimal Power Flow Determination

Optimal Power Flow (OPF) is one of the main functions of Power Generation Operation and Control. It determines the optimal settings of generating units, bus voltage, transformer tap and shunt elements in Power System with the objective of minimizing total production costs or losses while the system is operating within its security limits. The aim of this paper is to propose a methodology (ABCA-...

Statistical Monitoring of Rare Events in Healthcare

  There are miscellaneous quality characteristics in healthcare which are interested to be monitored. However, monitoring each characteristic needs a special statistical method. There are some characteristics with very small incidence rates that it’s usually considered not to be necessary to monitoring them, since their incidence rates are so small that p and np charts are not able to monitor t...
