Abstract

This paper presents a design, analysis and simulation of a hybrid electrical power system for an isolated community named Cartwright in Newfoundland and Labrador, Canada. The design aims to meet a peak energy demand of 902.24kW. In the selected renewable energy supply, the power-sharing ratio is tuned to 30% for solar Photovoltaic (PV) module and 70% for wind turbine power. The system is designed with the advanced HOMER Pro software to assess system performance under different scenarios. The aim of the design and analysis is to identify ideal configurations to propose sustainable solutions that address the energy needs of the community. This paper further displays a modeling and simulation process using the MATLAB/Simulink software. The simulation creates a prediction of the behaviour of the proposed system and reduces errors that may be present in the design process. The electric needs of Cartwright are met with 3,380 kW of solar PV system, 500 kW of generator capacity, 16,395 kWh of battery capacity, and 4,300 kW of wind generation capacity. The economic analysis results indicate operating costs amounting to $1.09M per year. This shows a total Net Present Cost (NPC) of $30,256,680 and a Levelized Cost of Energy (LCE) of $0.352/kWh.
