This approach increases distribution system reactive power demand, which may strain transmission system reactive power resources at times of system-wide high DG output, particularly if such output displaces synchronous generators. If a number of adjacent DGs are connected to a transmission node in a clustered fashion via a dedicated energy harvesting network (EHN), it is possible to characterise their aggregated reactive power capability as a form of virtual power plant. Such a characterisation will be provided in this paper. The aggregated capability may readily be included in transmission system models. This work will explicitly compare the transmission system voltage-control performance of EHN reactive capability with that of traditional synchronous plant.225657 bytes1072 bytesapplication/pdftext/plainenThis paper was presented during the 21ST International Conference on Electricity Distribution (CIRED 2011) held in Frankfurt on 6-10 June 2011.Distributed generation of electric powerEnergy harvestingElectric power transmissionConference Publicationhttps://creativecommons.org/licenses/by-nc-sa/1.0/
