Abstract

This paper presents the design and analysis of a hybrid power system for Port Hope Simpson (PHS), Labrador, using HOMER and MATLAB simulink. Port Hope Simpson (PHS) is one of the remote communities in Newfoundland and Labrador that rely heavily on fossil fuels for electricity generation. Presently, the electric need of PHS is met with three diesel generators rated, 725 KW, 550 KW and 500 KW which consumes more than 836,760 litres of fuel annually.. The operating costs of running the three generators are currently $1.62M per year. Hence, a new system is being proposed to reduce the operating cost of the system and transportation challenge faced during winter. Homer was used to design a new system which incorporates wind turbines, Solar PV and energy storage technologies with the existing three generators, while MATLAB was used to check the dynamic response of the system. The proposed system added 1,414 kW of PV, 1,571 kWh of battery capacity and 1,600 kW of wind generation capacity. This reduce the operating costs to $695,083/yr as against the $1.62M per year. The investment should have a payback of 2.87 years and an IRR of 34.8%. By optimizing the use of renewable resources and minimizing operational expenses, the hybrid power system can offer long-term economic benefits to the community.
