Abstract
Power quality studies are increasingly becoming a toast of major researchers as it is now a major factor utilized in determining the overall efficiency of an electrical power system. Voltage profile and power loss are significant pointers to the quality of power and as such, distributed generation comes into play since it offers competitive advantages over the traditional grid interconnected system. In this study, therefore, an attempt is made in comparing the voltage profile of the traditional grid system of a typical distribution network and with that incorporated with the distributed generation, using real data of a practical system of the Nigeria distribution company. The conceptual framework as well as the mathematical formulations required for the study are presented. The data are, then, simulated using a NEPLAN software. The results obtained from the simulations for power losses in both scenarios are examined. The results obtained clearly showed that there is a significant reduction in power losses and a substantial improvement in the voltage profile of an embedded generation in-feed scheme in comparison with the conventional grid in-feed.Keywords: Distributed Generation, Power Quality, Voltage Profile, Grid in-feed, Transmission LossesJEL Classifications: C63, L94, L98, Q48DOI: https://doi.org/10.32479/ijeep.11145
Highlights
Power plants utilize transmission grid networks to transmit energy over long distance and in the process of transporting the generated power, some of it is lost (Sayed and Massoud, 2019)
In order to reduce the reactive power losses associated with lines, we identified an overloaded line on Keffi-Fowler Line and incorporated the Unified Power Flow Controller (UPFC) on the line (Nick et al, 2017; Tong et al, 2019)
The competitive advantage that Distributed Generation has over traditional grid has been demonstrated using the NEPLAN simulation software with real data from the existing Power utility company
Summary
Power plants utilize transmission grid networks to transmit energy over long distance and in the process of transporting the generated power, some of it is lost (Sayed and Massoud, 2019). Distributed Generation systems can help to guide against congestion due to peak demand on the network (Jenkins and Strbac, 1997; Zhao et al, 2013). This does not come without its attendant challenges which include location and size, system performance, short circuit power and fault current level, reverse power flow and voltage profile, reduced reach of impedance relay (Dulău et al, 2014; Zhao et al, 2013). Distributed generation offers the advantage of postponing major investment costs on the networks and cutting down the transmission and distribution energy losses (Baghaee et al, 2016)
