This study investigates the performance and feasibility of deploying a 5-kW horizontal-axis wind turbine(HAWT) in an urban setting, specifically on the rooftop of a high-rise building at Ain Shams University.Given the complex and turbulent wind patterns in urban areas, this research assesses key parametersincluding power output, wind velocity, and directionality, with a focus on optimizing turbine efficiencyunder variable wind conditions. The turbine’s performance was experimentally monitored, and poweroutput was correlated with wind speed to derive an urban-specific power curve. Results indicate that theturbine operates optimally within a moderate wind speed range, with an average power output ofapproximately 2 kW, a peak measured power of about 2.5 kW at a wind speed of around 7.75 m/s, and amaximum efficiency (Cp) of 0.35. Structural analysis confirmed that the load on the rooftop is acceptable,making the turbine feasible and practical for rooftop installation. Additional considerations, such as yawcontrol and monitoring systems, were integrated to enhance the turbine's adaptation to the urbanaerodynamic environment. This paper contributes valuable insights for the effective design andimplementation of small-scale wind energy systems within urban microgrids, promoting sustainableenergy generation in densely populated areas.
