Design, sizing and operation of a hybrid renewable energy system for farming

This study presents a hybrid power system using wind turbine and solar PV to supply power to farms. A simple yet robust method for sizing of the renewable generators is developed. Two operation schemes are investigated. A case study at a farm in California suggests that, by using renewable energy, the hybrid system can save over $600K for the farm over 20 years. Furthermore, non-critical farm loads, such as water pumping system, can be operated flexibly to achieve greater saving of energy. In addition, the farm power supply can be maintained in part or in full by islanding the farm.
