Operational Analysis of a 34 KWP Grid-Connected PV System Considering Local Weather Measurements in Central Brazil
Abstract
More and more distributed generations systems have been connected to the power system in Brazil, especially PV systems in the range between a few units (residential) to hundreds (power plants) of kW. On that context, this work is related to operational analysis of a new 34 kWp grid-connected PV system based on local weather conditions measured in the city of Goiania, located in Central Brazil. The PV system had been installed by a research and development project approved by ANEEL (Brazilian Electrical Energy Agency) and it was the first rooftop solar plant installed at UFG (Federal University of Goias) and also among other public universities from Central Brazil. After some basics operational tests, that 34 kWp grid-connected PV system started to work continuously on January 2017 after being registered and authorized by local grid utility. Since then an amount of 4.4 MWh has been generated and fed into the power distribution line up to middle of October 2017. Results registered during February 2017 from an existing and active PV plant were chosen to present a possible operational analysis. At the end, the energy and power performance profiles from grid-connected PV system are discussed in terms of weather measurements and conditions. As a fully one operational year from 34 kWp grid-connected PV system has not been concluded yet, authors still working on its performance analysis.
