“…In order to minimize the photovoltaics (PV)-installation space concern, it is assumed that the rooftops of the buildings in the university are used. Because a 3 kW-capacity photovoltaic panel requires 7 m 2 [34,35], the maximum limitation of PV panels was computed as about 99,000 kW.…”

Abstract:In order to minimize the social and environmental concerns arising from the use of traditional energy resources such as fossil fuels and nuclear energy, the South Korean government has attempted to develop alternative energy resources. In particular, the large educational institutes and islands in South Korea-which have the motivation and potential to provide electrical services-are required to install renewable electricity generation facilities to reduce the burden on the local grid systems. With this trend, the current study investigates potential configurations of renewable electricity generation systems to supply the electrical demand of Jeju National University, located on the largest island in South Korea. The potential configurations suggested by the simulation results are evaluated by renewable fraction, cost of energy (COE), and total net present cost (NPC). The suggested configurations show a renewable fraction of 1.00 with COE of $0.356-$0.402 per kWh and NPC of $54,620,352-$51,795,040. Based on the results, both implications and limitations are examined.

Continued reductions in air pollution and greenhouse gas (GHG) emissions are crucial in megacities like Tehran, Iran, as they pose serious threats to both people's health and the environment. Reducing energy use through renewable energy projects will result in the mitigation of GHG emissions. Hence, this study was designed to assess the use of renewable energy resources to provide the energy services for a residential building. The specific objective of this article is to select a hybrid renewable energy system that can meet the energy demand of a 5‐story residential building in Tehran. The energy consumption of the building is calculated using DesignBuilder software. Then, HOMER software is applied to propose an economically feasible solar‐wind hybrid system that can meet the energy demand of the building. Initially, information required for HOMER and DesignBuilder software such as the building plan, details on electrical appliances used in the building, solar radiation, wind speed, and cost of renewable systems were collected. Subsequently, the energy performance of the building was simulated in DesignBuilder software and the results were applied to HOMER software. Finally, the hybrid systems proposed by HOMER were economically compared. Furthermore, the emissions produced by the proposed system were evaluated against a diesel only system to assess the amount of offset emissions. The comparison of the hybrid and diesel systems shows that utilization of hybrid systems can significantly reduce the magnitude of GHG emissions along with achieving cost saving. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

The randomness of generated power by renewable energy resources has led experts in this field to provide sustained and permanent load supply with hybrid renewable energy systems (HRESs). This study investigates the modeling of an off‐grid HRES based on the wind turbine/photovoltaic/gas generator for supplying the consumption of a residential complex in Tehran (capital of Iran). To this end, the HOMER software has been implemented. After calculations, the capital cost and cost of energy of each component are estimated in different HRES models. In addition, parameters such as power generation, emissions, and thermo‐economic analysis of different models of the hybrid system have been investigated. Two models of optimum HRES (based on the lowest net present cost [NPC]), with and without wind turbines, were compared. According to the results, the fuel consumption and emissions caused by the operation of the gas generator will decrease by 53% as a result of using a wind turbine despite an 8% increase in NPC. This is an important achievement regarding high air pollution in Tehran. Based on the results, using a gas generator instead of a diesel generator leads to an 18% decrease in NPC. Additionally, in comparison to using a gas generator only, using the hybrid system leads to a 43% reduction in NPC.
