— The prospect of utilizing wind energy for electricity generation in urban areas seems to be inefficient, owing to low wind speeds and the turbulence caused by surrounding obstacles. However, these challenges can be overcome by integrating a power augmentation device called an omni-direction-guide -vane (ODGV) to further increase the oncoming wind speed for better performance of wind turbines. This study aims to investigate the influence of the ODGV in the feasibility and optimization of a stand-alone hybrid renewable energy system in a low wind speed area in Malaysia. The HOMER (Hybrid Optimization Model for Electric Renewable) software package was used for the analysis of the simulation. Two case scenarios were analyzed, case 1, is using Wind-PV-Diesel-Battery system with the presence of the ODGV and case 2 is the Wind-PV-Diesel-Battery system without the presence of ODGV. Thousands of simulations were carried out to achieve optimal autonomous system configurations. Four scenarios were evaluated in both cases. The assessment criteria comprises of the Net Present Cost (NPC), Cost of Energy (COE), amount of CO2 emitted and the Renewable Fraction (RF). Comparison was made between the best scenarios in case 1 and case 2. The results indicate that scenario 1, in case 1 (WT-PV-DG- Battery) system is the most feasible, optimized, cost effective and environmental friendly system among other configurations . The economics analysis reveals that with case 1 scenario 1, $4,795 of the total NPC and $0.021/kWh of the COE can be saved respectively. Moreover, the results of the environmental analysis indicates that 438kg/yr (2.3%) of CO2 emitted could be reduced by the system in case 1 scenario 1 and 25% of renewable fraction is achieved
