Analysis of Autonomous Hybrid Wind/Photovoltaic Renewable Energy System with Load Variation

Hybrid energy system is the integration of wind, solar, hydro, biomass, into one system. Over the years, electricity generation in Nigeria has depended solely on burning of cheap fuels contributing to damage to the environment. Solar energy system through direct conversion of solar irradiance into electricity can be used as electrical power source for homes and remote areas to meet its daily energy requirement. In this project, detailed design of a hybrid photovoltaic system and wind turbine system for uninterrupted power supply for a residential building in a typical urban area is presented. Accomplishment of the process depends in a variety of factors such as geographical location, weather condition, solar irradiance, and load consumption, using the software called HOMER. The project outlines in details the procedures for specifying each components of the hybrid  power system and as a case study, a residence in Port Harcourt Nigeria having latitude of 4.46N and a longitude of 7.01E with typical energy consumption is selected. An average AC load of 47.97kWh/day was considered. The capacity of the PV module was 23kW, the wind turbine was 3kW, system converter of 5.94kW, and 1kWh lead acid battery was also used.
