Abstract: In this study, an optimal sizing for building integrated hybrid photovoltaic, diesel generator and battery system for zero load rejection is performed. The optimization is obtained by considering the loss-of-load probability (LLP) of the system less than 0.01. For this system, the average daily solar radiation is collected from ‘Thondamuthur’ region, Coimbatore. The load demand is collected from Civil Department building of Karunya University. The optimization presented in this study aims to calculate the optimum size of a PV array and diesel generator, and battery which examine the minimum system cost. An optimization problem in terms of system unit cost is solved graphically in this study. The results of the optimization show that a photovoltaic/diesel generator choice is more feasible compared to a standalone photovoltaic system or diesel generator system.
