Design and Simulation of a Hybrid Renewable Energy System for a Farmhouse in Balikesir, Turkey

In this study, a hybrid renewable energy system capable of operating in stand-alone mode  while exporting surplus electricity to the grid is designed and analyzed for a farmhouse  located in Ovaköy Village of Balıkesir Province, Türkiye. The system is designed to meet  both residential and agricultural electricity demands. The daily electricity consumption is  determined as approximately 10 kWh, consisting of 8 kWh for household use and 2 kWh  for farm-related activities such as cleaning and irrigation. The proposed hybrid system  includes photovoltaic panels, a wind turbine, a biogas generator, battery storage, an  inverter/converter, and a grid connection. A daily biomass availability of 1 ton is assumed  for the biogas generator. The system design and optimization are carried out using the  HOMER software, and various configurations are evaluated in terms of technical and  economic performance. Simulation results indicate that the system achieves a high  renewable energy fraction, ensures reliable power supply, and provides economic benefits  through surplus energy sales to the grid. The findings demonstrate that hybrid renewable  energy systems offer a sustainable and feasible solution for rural agricultural regions such  as Ovaköy Village.
