Active Power Correction Strategy Research In Reliability Worth Assessment Of Composite System

With power market being continually boosted throughout the world, some problem on the reliability worth have received broad attention and active power correction strategy of power system hi reliability worth assessment has happened new changes that the process of power correction needs come down to a series of adjustment cost rather than conventional instruction action. From the view of operation, three active power correction strategies in reliability worth assessment of composite power system are researched and compared by sensitivity arithmetic based on taxis indexes, and on the basis of the software platform for reliability worth assessment, the correspondent software for reliability worth assessment is perfected and exploited in this thesis. At the same time, the assessment in allusion to adjustment cost at the generation side and interruption cost at the consumer side related to the course of active power correction has been preliminarily studied.The software has tested reliability and reliability worth indexes for composite power system on IEEE 24 bus Reliability Test System, and compared the economic efficiency of three active power correction strategies. Finally, the results indicate that the charge of active power correction strategy thinking over adjustment cost will reduce. The conclusion is consistent with expectant research.
