System and method for accelerated assessment of operational uncertainties in electrical power distribution systems

摘要

A system for accelerated assessment of operational uncertainties in an electrical power distribution system includes a plurality of utility assets, and a distribution analysis (“DA”) system. DA system includes a preparation module configured to identify a first network model and a reduced network model for the electrical power distribution system. DA system also includes an input module configured to identify a plurality of scenarios, and a reduced-model-analysis module configured to analyze the reduced network model using the plurality of scenarios, generating a first set of results, and to select a subset of scenarios based on the first set of results. DA system further includes a full-model-analysis module configured to analyze the first network model using the subset of scenarios, generating a second set of results. DA system also includes a command module configured to dispatch configuration commands to utility assets based on the second set of results.

1. A system for accelerated assessment of operational uncertainties in an electrical power distribution network, said system for accelerated assessment of operational uncertainties comprising:
a plurality of utility assets; and a distribution analysis system comprising:
a preparation module configured to:
identify a first network model for the electrical power distribution network wherein the first network model includes a plurality of segments and a plurality of loads coupled to the plurality of segments, each segment of the plurality of segments having an impedance; andidentify a reduced network model for the electrical power distribution network, the reduced network model including an aggregation of the plurality of segments and a combination of the associated impedances, the plurality of segments including at least two retained segments and merged segments between the at least two retained segments, the at least two retained segments and the merged segments aggregated into a single segment, whereby the impedances of the at least two retained segments and the impedances of the merged segments are combined into one impedance and the reduced network model further including a plurality of lumped loads, wherein each lumped load of the plurality of lumped loads represents one or more individual loads aggregated into a single load, wherein the plurality of lumped loads are not bundled with the plurality of impedances and facilitate examination of the reduced network model with different loading scenarios;an input module configured to identify a plurality of scenarios;a reduced-model-analysis module configured to:
analyze the reduced network model using the plurality of scenarios, thereby generating a first set of results; andselect a subset of scenarios from the plurality of scenarios at least partially based on the first set of results;a full-model-analysis module configured to analyze the first network model using the subset of scenarios, thereby generating a second set of results; anda command module configured to dispatch at least one configuration command to at least one of the plurality of utility assets at least partially based on the second set of results.
