- Energetic system with biomass and how to mitigate associated problemsPublication . Nabais, Adelino S.; Galvao, Joao R.; Ascenso, Rita M. T.; Leitao, Sergio A.In this work we present a greenhouse case study with a new energy model based on a Biomass energy source, once it is a more profitable and sustainable energy system, but demands special safety measures. Biomass has some dangerous aspects along the process from transport, to storage until its’ use. The paper foccus on safety for equipment operation, storage of biofuels, the design of the facilities and health of the employees, in a context of primary renewable energy source of greenhouses farming systems, for intensive cultivation of flowers and vegetables for human consumption. Similarly, exposure to biologically active material (mustiness and spores) may constitute a danger to the health of those involved in handling biomass. These properties and their use determine safety conditions in handling and storage. This energy model is constituted with several proposals, both technological and energy alternatives/renewable energy, to meet the needs of electric power and heat, with the objective of increasing the competitiveness in agricultural greenhouses, in the management, financial and environmental aspects. The model was developed with the purpose of improving efficiency and sustainability, with the inclusion of sensors that allow controlling the various components of a greenhouse, with the perspective of a quick distribution in the market, increasing the economic benefits and supported on efficient and intelligent management systems energy.
- Greenhouse with Sustainable Energy for IoTPublication . Oliveira, Filipe Tadeu; Leitão, Ségio A.; Nabais, Adelino S.; Ascenso, Rita M.; Galvão, João R.In order to support the intensive development of agricultural crops and, in particular the floricultural inside a greenhouse, with the perspective of a quick distribution in the market, increasing the economic benefits and supported on efficient and intelligent management systems energy, it is mandatory to conceive a model based on Cyber-Physical Systems (CPS) This implies, accordingly, increases in renewable primary energy sources utilization coupled with sensing technologies, include developments on Internet of Things (IoT) and Cloud Computing (CC), supported with Information and Communication Technologies (ICT) that will lead to new architectural approach applied to a proposed energy system, based on a sustainable and more engineering autonomous process. This work comes up with a new energy model that retrofits the system of a greenhouse supported with multiple sensors in one grid, to expand into CPS concept to manage sensors and controllers that will improve a profitable energy system.
