Experimental evaluation of active filtering in a single-phase high-frequency AC microgrid / Sudipta Chakraborty in IEEE transactions on energy conversion, Vol. 24 N° 3 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 3 (Septembre 2009) . - pp. 673 - 682 Titre : Experimental evaluation of active filtering in a single-phase high-frequency AC microgrid Type de document : texte imprimé Auteurs : Sudipta Chakraborty, Auteur ; Simoes M.G., Auteur Année de publication : 2010 Article en page(s) : pp. 673 - 682 Note générale : Energy Conversion Langues : Anglais (eng) Mots-clés : Distribution  networks--Power  filters--Power  supply  quality Résumé : Population growth in the world along with rapid technological expansion of the society demand efficient, economically viable, and environment-friendly energy conversion systems. The previous theoretical and simulation works have demonstrated that a 500-Hz single-phase high-frequency ac (HFAC) microgrid is a novel step toward integrating renewable energy sources in a distributed generation system. This paper goes one step further in describing the practical implementation of HFAC microgrid with active filters for a small 1-kW system. The protection issues for both the source and series converters are also addressed in this paper by developing a new but simple protection scheme. In the experimental microgrid system, a universal active power line conditioner (UPLC) and a unified power quality conditioner (UPQC) are incorporated to control the power flow and power quality, respectively. Controllers for both the UPQC and UPLC are developed based on the instantaneous single-phase p-q theory, and controlled pulsewidth modulated inverters are then implemented to synthesize the desired compensating waveforms. The experimental results obtained confirm that the HFAC microgrid is a practical and useful step toward successfully integrating distributed renewable energy sources ensuring the improved system utilization.
