Power-quality events are of increasing concern for the economy because todaypsilas equipment, particularly computers and automated manufacturing devices, is highly sensitive to such imperfections. With volatile energy rates and a need to control costs, regional agencies and utilities are interested in technologies to meter distribution use and manage utility information. Metering technologies and...
Modern distribution systems include the presence of generation units, namely Embedded Generation (EG), that can affect the Power Quality (PQ) levels inside the systems. This paper concerns with the analysis of PQ effects linked to the installation of fuel cell based production systems. Site and system indices are proposed to quantify these effects in terms of slow voltage variations, harmonic pollution...
