Dimensionamento técnico e econômico dos sistemas fotovoltaicos para data centers: um estudo de caso.

Abstract

The energy consumption of modern Information Technology (IT) has been increasingly gaining the attention of large technology companies, as it represents a significant portion of electrical energy consumption in the world. Part of this energy consumption occurs due to IT equipments that requires uninterrupted operation to ensure the functioning of numerous services that depend on computer networks. In this sense, the search for innovations in the energy supply for those equipments, so present in data centers, is a necessity, to guarantee the sustainability and safety of their operations. The present work aimed the technical and economic dimensioning of hybrid photovoltaic systems for tiers I and II data centers, based on the case study of the data center in the Centro Administrativo of the Prefeitura de Paracatu – Minas Gerais (MG). The sizing was carried out using the HOMER Pro software, a powerful tool capable of designing hybrid power generation systems and indicating the best configurations for the system, using technical and economic criteria. With this software, it was possible to verify that the tier II data center configuration is more advantageous than the tier I data center configuration, according to the lowest net present cost criteria.
