Design Methodology of Off-Grid PV System

Abstract

This paper develops a novel design methodology for the off-grid PV system by applying the demand- side management (DSM) approach. DSM strategy is used for the optimal distribution of electrical energy among the load. Various types of load are being categorized based on priority. In the case of a power shortage, the top- priority load will get a more reliable power supply. Moreover, energy shortage will get distributed among the loads. A programming model has been designed for a DSM-based off-grid PV system. Two cases have been considered. In the first case, the program is allowed to run under poor solar insolation conditions with DSM and in the second case, the off-grid system has been analyzed without DSM under poor insolation conditions. It is found that DSM based off-grid PV system is a better option as it supplies more reliable power as well as providesmaximum customer comfort as compared to without a DSM-based off-grid PV system.
