Optimization and modeling of a stand-alone wind/PV hybrid energy system

Microwave repeaters are one of the main energy consumers in the telecommunication industry. These repeaters are powered using diesel generators and batteries, particularly when they are located in remote areas. Diesel generators require higher maintenance cost and for remote sites this cost will be more due to the added oil transportation cost. The aim of this paper to optimize and model a hybrid energy system for a microwave repeater located in Mulligan, Labrador, Canada. The hybrid system is a combination of wind, solar, diesel generation and batteries. Hybrid Optimization Model for Electric Renewable (HOMER) software is used for the sizing, and sensitivity analysis is performed in order to obtain the most feasible configuration of a hybrid renewable energy system. The proposed hybrid system is finally modeled in SIMULINK and results are presented to demonstrate the system performance.
