“…They reported that the cities in the southern and central parts of the country have power classes ranging between 1 and 4. Ozioko et al (2022) evaluated the impact of wind energy penetration on the Nigerian power grid, especially when replacing the conventional fossil fired generator with doubly-fed induction generator (DFIG)based wind turbine generators. Their study focused on the connection of power generated from wind turbines to the national grid and not on actual wind power generation or assessment.…”

Wind energy is a promising sector in the power generation industry because it is renewable and globally available. In this research work, the wind energy potential and the economic viability of using wind turbines to generate electricity in some selected sites along Nigeria’s coastline and offshore locations were evaluated. Using the statistical two-parameter Weibull probability density function method, wind speed data retrieved from an indigenous oceanography company and global information system (GIS) were analyzed for wind energy harvest. The energy output, unit cost of electricity generated by three commercially available wind turbine models (3 MW, 4 MW, and 6 MW), net present value (NPV), and payback period were evaluated. Levelized cost of electricity (LCOE) sensitivity to the discount rate, foundation cost, and turbine lifespan were also examined. The findings from the study showed that the offshore sites have four times greater wind power potential than the coastal sites. The offshore sites can be categorized as “class IIIb” wind sites, making the locations suitable for wind energy harvest. The techno-economic analysis showed that the net gains from investing in a 60-MW wind farm in the region can be as high as $62,000,000.00, while the project payback time can be as low as 5.74 years. Two of the offshore sites are recommended for the development of an offshore wind farm in the country because of their relatively low LCOE (0.04 $/kWh), higher NPV, and lower investment payback time. The Vesta-117 model wind turbine is the most suitable wind turbine system and recommended for use in the region because of its low cut-in speed (3 m/s). Sensitivity analysis showed that the LCOE of offshore-01 was reduced by 31% when the lifespan of the V117 turbine was increased from 20 to 25 years. The results also showed that reductions in the discount rate and foundation cost positively affect the LCOE.

“…While Li et al [10] proposed a fault control mechanism to enable up to 90 % wind energy integration, whether the grid remains stable for such integration remains uncertain. Ozioko et al [11] found a 10 % penetration limit for DFIG-based wind farms on the Nigerian grid, noting no improvement in voltage profile due to PQ-controlled integration. Adetokun et al [12] suggested using large-scale solar photovoltaic energy to enhance the grid's voltage profile based on load flow analysis, but further dynamic simulation and power loss investigations are needed to confirm system stability under large integration.…”

“…Recognizing the stochastic nature of the wind, the integration of the energy produced in the electrical energy network remains more problematic [13], but the development of electronics in this field has influenced the reduction of this problem [14,15]. Another study [16] found that in the case of the large integration of wind farms in an energy network, it is important to try to make the points of connection-integration scattered and not close to each other. The reason here lies in the fact that when the number of farms connected to the public grid is large from a single station, power losses will increase.…”

Most of the countries in South-East Europe primarily depend on fossil fuels to cover their energy demands. The paper discusses the future perspective on wind energy in the country, where over 90% of energy is generated in coal-fired thermal power plants. Given the energy crisis, that has gripped the world, the possibility of covering the increased energy demand is being studied, especially during the winter. Based on current trends on energy generation, with just symbolic participation of wind, hydro and solar energy, the potential for maximization of the use of wind energy is considered, which means the use of each identified adequate location throughout the country. The main advantage here is that the maximum energy produced by wind is during winter when demand increases. This is important to know that Kosovo faces significant heating problems and its demand is covered with electricity. Analyzes prove that the country has a generous wind capacity, which reduces to a certain extent the need to import and even enables the export of energy under certain conditions. The potential installation capacity in Kosovo is 510.9 MW, of which 32.4 MW is currently in operating conditions. From the analysis made for the current wind farm in operation, the plant capacity factor is 31.8%. The study of the results indicates a direct correlation between the increase in load during the winter season and the electricity production by wind farms, thereby, the energy demand can be sufficiently covered.
