Analysis of the PV system sizing and economic feasibility study in a grid-connected PV system

Abstract

UAE has good weather conditions for the integration of renewable energies in utility grid, especially photovoltaic solar energy, as it is one of the countries with the highest rate of solar radiation in the world, thus being able to contribute to policies to reduce greenhouse gas emissions. This article presents a study on how to control the variability that the production of electricity from solar energy presents and how to improve the integration of this type of production for self-consumption in an installation. Thus, in addition to a survey on the legislation that regulates the activity of self-consumption, topics such as energy storage, photovoltaic production and the optimization of the dimensioning of production systems with storage were addressed. The dimensioning process of a photovoltaic system connected to the grid is based on the choice and suitability of the module and DC/AC inverter and other peripheral equipment. The inverter sizing factor is the relationship between the inverter power and the PV generator power, and your choice depends on several factors. In addition, this work aims to in addition to presenting a study regarding economic feasibility so that it is possible to assess the profitability of this technology for the selected building.
