One-Year Monitoring PV Power Plant Installed on Rooftop of Mineirão Fifa World Cup/Olympics Football Stadium

Abstract

This paper presents results of one-year monitoring of AC side electrical parameters and the characterization of local solar radiation at the biggest rooftop PV Power Plant, with an installed capacity of 1.42 MWp, mounted at Mineirão Football Stadium in Brazil. This stadium is one of the sport facilities that hosted 2014 FIFA World Cup and Rio 2016 Summer Olympics Games in the country. Results showed how it is important to study and characterize the solar resource in the region of interest, based on historic data, to provide the understanding of solar radiation and thus project PV power plants with better performance. Furthermore, AC electrical data show the behavior of active, reactive and apparent powers and the influence of the PV system on the power factor at the local grid utility connection point. Finally, PV power plant performance data (as annual final yield, performance ratio and capacity factor) are also presented and compared with data from PVsyst software simulations. The results over the monitoring period were good considering the specificities of the stadium.

Field I-V Curve Measurements Methodology at String Level to Monitor Failures and the Degradation Process: A Case Study of a 1.42 MWp PV Power Plant

“…Figure 2 shows an aerial observation of the stadium with the 1.42 MWp PV generator rooftop, an overview of the whole system. More details on this installation can be found in [22,30,31].…”

“…The study presented in [22] analyzed the performance ratio (PR) for the Mineirão Stadium PV plant for over a year of measured data. The monthly PR results calculated from nameplate data for installed PV power (1.42 MWp) are represented in the light gray bars of Figure 16.…”

“…The energy production was reduced by approximately 16.5% in the dry period and 8.0% after a rainfall period. Monteiro et al presented in [22] outcomes of a one-year monitoring campaign of AC side electrical parameters for the characterization of solar radiation area at the most giant rooftop PV Power Plant, with an installed capacity of 1.42 MWp, installed at Mineirão Football Stadium (Brazil). The authors showed how important it is to survey and characterize the solar resource in the stadium area, based on historical data, to understand solar radiation and design PV power plants with better performance.…”

“…The works cited above [21][22][23] do not specify in detail what level was analyzed for a photovoltaic generation or do not perform a full study of commissioning/quality assurance to compare nominal data with data measured in real operational conditions.…”

Análise do Controle de Potência Reativa de Sistemas de Armazenamento em um Alimentador de Distribuição Real

“…O sistema utilizado neste trabalhoé um alimentador real de média tensão, localizado em Belo Horizonte -MG. Este alimentadoré responsável pelo suprimento de energia de parte da Universidade Federal de Minas Gerais e do estádio do Mineirão, tendo uma carga média de 2,6 MVA com o pico de carga podendo atingir 6 MVA. A usina fotovoltaica do estádio mineirão, cujos detalhes são descritos em Monteiro et al (2017), que conta potência instalada de 1420 kWp e capacidade de injeção de potência de 1320 kWp,é conectada ao alimentador. Está prevista a instalação de dois sistemas de armazenamento com baterias, um com capacidade de energia de 1 MWh e potência de 750 kVA utilizando baterias deíon-lítio e o outro com capacidade de energia de 750 kWh e potência de 400 kVA utilizando baterias de chumbo-ácido avançado.…”
