Sizing of Photovoltaic array and battery using simplex method for standalone Photovoltaic system

Abstract

Photovoltaic system is emerging as a major power resource, steadily becoming more affordable and proving to be more reliable than utilities and promises a brighter, cleaner future. Photovoltaic system can be grid connected or standalone, both have their advantages and disadvantages. As most of the Photovoltaic systems are standalone, so to avoid the problem of islanding a proper size of the Photovoltaic system should be adopted to give a reliable system. Sizing of photovoltaic system is the process of designing, selecting and calculating the ratings of the equipments employed in the system. This process depends on a variety of factors such as geographical location, solar irradiation, and load requirements. In this dissertation, sizing of standalone photo voltaic system is done using linear programming problem (LPP) approach. LPP provides upper bound reliability for application and rich information for many extreme events. A method of sizing stand-alone photovoltaic systems regarding the reliability to satisfy the load demand is presented in this work.
