Considerando o estresse hídrico vivido pelo mundo na atualidade e o desafio da geração deeletricidade sustentável, a utilização da água no setor elétrico é uma importante questão a serestudada. Dessa forma, este trabalho pretende contribuir para um planejamento eficaz depolíticas integradas de energia e água. No Ceará, 65% da energia é produzida por tecnologiasde usinas termelétricas (UTEs) a carvão e gás natur...
This article presents the use of two mathematical models (MM) developed for photovoltaic modules (PVM). These are known as MM 4-parameter model - 4P (IL; I0; RS; a) and model parameters 5 - 5P (IL; I0; RS; Rsh; m). In this work were initially designed photovoltaic characteristic curves (IV). Then those curves were compared with the curves shown in PVM manufacturer's catalog used (KYOCERA the KC85T). It was noti...
One of the technical restrictions on the dissemination of solar projects is the low efficiency of photovoltaic systems, which promotes a search for alternatives to maximize the use of solar irradiation in these systems. Among these alternatives is the use of solar tracking, which causes the solar capture surface to face the sun, following its movement and thereby capturing more irradiation. Thus, in the present...
This article presents a study on the bi-directional DC-DC Converter with Dual Active Bridge Tri-State Switching cell for use in photovoltaic systems and battery bank. It is shown the proposed system for application, the converter operating principle, its ability to charge and discharge a battery bank with a combination of photovoltaic panels, and other features. This battery bank has a nominal voltage of 48 V, ...
The energy-water nexus is a challenge that can affect the electricity production of Ceará (CE), especially in long periods of drought. This dependence is more evident due to the fact that the state's current matrix has four thermoelectric plants (Porto do Pecém I and II, Termofortaleza, Termoceará), which demand a high amount of water, and the concurrent use of limited water resources. Based on this motivation,...
