Impact of Distributed Generation from Solar Energy on Power System Distribution in Nigeria
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 2
Abstract
Distributed generation (DG) are electrical power generations designed at the customer load site. They have the ability to reduce technical losses, improve voltage profile and power quality. When adequately installed, it saves cost by averting the need for investment in the transmission and distribution infrastructure. This research was detailed study and analysis of the benefits of DG from Solar Renewable Energy with the Dumez feeder network of Otovwodo 15MVA, 33/11KV Injection Substation in Nigeria as a case study. This work is of great practical relevance to the society and country at large, the research methodology involved actual collection of relevant data from a typical existing Nigeria Power Distribution network. The network was modelled in Electrical Transient Analyzer Program [ETAP 7.0] software. The power flow was on Newton-Raphson power flow algorithm embedded in ETAP 7.0 software to determine bus voltages, power losses and load flow report for the existing network, Case I DG and Case II DG respectively. The load flow analysis showed that the total losses in the network without DG is 722.7KW, 972.8KVar. Under steady state condition, forty-six (46) buses recorded voltage violations. Only Otovwodo bus was within the marginal voltage acceptable limit with 97.8 %. Case I DG, the losses reduced to 397KW, 492.1KVar. Voltage violation reduced to thirty-nine (39) buses. Case II DG, losses further reduced to 349.1KW, 524.0KVar. All buses fall within marginal voltage acceptable limit. Case II DG, showed the network were within the voltage statutory limit of ± 6%.
