Abstract: The primary purpose in constructing equivalents is to represent a portion of a network containing many buses but having only a few "boundary buses" by a reduced network containing only the boundary buses and, perhaps, a few selected buses from within the original sub-network. The equivalent constructed gives an exact reproduction of the self and transfer impedances of the external system as seen from its boundary buses. PowerFactory’s network reduction algorithm produces an equivalent representation of the reduced part of the network and calculates its parameters. This equivalent re-presentation is valid for both load flow and short-circuit calculations, including asymmetrical faults (that is, single-phase faults).Abstract: The primary purpose in constructing equivalents is to represent a portion of a network containing many buses but having only a few "boundary buses" by a reduced network containing only the boundary buses and, perhaps, a few selected buses from within the original sub-network.

Abstract: The concluding part of this work (Part III) presents the non-probabilistic (deterministic) assessment of failure effects under given contingencies and reliability analysis is an automation and probabilistic extension of contingency evaluation. Also, PowerFactory generation adequacy tool is design specifically for testing of system adequacy using Monte-Carlo method. Running adequacy analysis produces convergence plots, distribution plots and Monte-Carlo draw plots. PowerFactory’s contingency analysis module offers two distinct contingency analysis methods: single time phase and multiple time phase contingency analysis, while an analytical assessment of the network reliability indices is initiated by the following actions (failure modeling, load modeling, system state production, failure effect analysis (FEA), statistical analysis and reporting) within PowerFactory. Lastly, voltage sag analysis is a calculation that assesses the expected frequency of voltage sags within a network.Abstract: The concluding part of this work (Part III) presents the non-probabilistic (deterministic) assessment of failure effects under given contingencies and reliability analysis is an automation and probabilistic extension of contingency evaluation.
