Dynamic modeling and simulation of the rooftop PV system for the First Passive House in Newfoundland

Abstract

This paper presents the design and modelling of a photovoltaic (PV) system for the first house in Newfoundland built under the guidelines of the Passive House Institute United States (PHIUS+2015). The proposed PV system is optimized with the use of HomerPro software to get 9.75kW of PV panels with a battery storage system. Detailed modelling of the system is finally completed in MATLAB/Simulink with the implementation of a charge controller, MPPT controller, and 8kW of single-phase DC to AC converter. The simulation results show the stability of the system and the advantage of the Grid-connected PV system with a battery backup. System design, detailed modelling and some simulation results are included in the paper. Finally, the cost of the designed system has been compared with the electricity bills considering saving and using Homer optimized results; the feasibility of the proposed system is presented.
