2019

With consideration of the increasing energy demand and deficit of fossil fuel resources, the best way for the conquest of renewable resources alternation is the use of hybrid system. In this research, the performance of wind-photovoltaic hybrid system for providing the required electrical energy for a big ministerial building in Kermanshah city is investigated. The required electrical load for the month of a year was calculated 178000 kWh/year by using average electrical energy consumption. With consideration of wind average velocity for hours of a year, Weibull and Rayleigh distribution functions for this location was determined. Also, the power and annual energy of each turbine using wind speed data was calculated. The amount of average solar radiation by use of solar energy relations was calculated, and then, with consideration of annual total energy, the required annual wind energy versus solar cell surfaces selection was determined. Finally, the type and number of turbines by using of their technical specification for each surface selection of solar cells was determined and the performance of hybrid system including 300 m 2 photovoltaic solar cells and a

Assessing the possibility and economical considerations of solar-wind based hybrid power generation in Green buildings

The present power crisis and global scenario trend is favouring renewable energy sources like solar and wind power. Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. The accurate assessment of solar and wind potential for an area requires both the knowledge of probability density function and the power density of both solar and wind. For this purpose, for the area of interest are required databases that to contain direct measurements of solar and wind parameters recorded during at least one year. But, Site measurement of these information requires time and money that often are not available for small micro-generation projects. In this Paper a methodology has been developed to how to assist an existing Solar system with Wind power. This study will demonstrate the importance of Hybrid system applicable to a green building.

Size Optimization of a Grid-Connected Solar–Wind Hybrid System in Net Zero Energy Buildings: A Case Study

Environmental Sciences Proceedings, 2022

This study proposes a hybrid renewable energy system consisting of photovoltaic panels and a wind turbine to supply the total or part of the demand of a grid-connected residential building and presents the optimal system size using a genetic algorithm. Wind speed, solar irradiance, and electricity demand are monitored in 15 min intervals over a year. It is found that the optimal values for PV panels’ area, rated power of the wind turbine, and the tower height are 148.5 m2, 1.5 kW, and 20 m, respectively. These optimal values lead to a total system cost of EUR 42,218 over 20 years.

Feasibility analysis of solar photovoltaic-wind hybrid energy system for household applications

Computers & Electrical Engineering, 2020

The significance of renewable energy resources provide a great opportunity to meet a single household electricity demand in Northern Cyprus. Purposefully, a 6 kW PV-Wind hybrid system seems to offer significant economic savings relative to the conventional grid system. Therefore, the main intention is to shed light on the technical as well as economic feasibility of combining renewable sources. The solar irradiance and wind speed data are analyzed for four populous cities of TRNC using RET-Screen software. The expected energy consumption for a normal household in Northern Cyprus comes out to be 11.27 kWh/d using HOMER software. The proposed hybrid model integrated with Ni-MH battery is designed in MATLAB software to visualize the possible energy output to be feed to the load. The results show that the proposed model provides alternative incentives to the consumers and it is economically feasible.

SOLAR & WIND HYBRID POWER SOURCE FOR RESIDENTIAL BUILDING MATHEMATICAL MODEL APPROACH

Solar and wind are clean energy sources with capability of decreasing grid dependence. The aim of this paper was to present them as possible sources of an electrical energy in a residential building. To roll out principles and realize given objective functions of a hybrid power system a mathematical model has been developed. Conducted calculations have shown that the solar energy is more stable and predictable energy source than wind, however the combination of both allows reduction in capacity of a battery bank.

Techno‐economic assessment of hybrid renewable resources for a residential building in tehran

Environmental Progress & Sustainable Energy, 2019

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.

Techno-Economic analysis of the potential utilization of a hybrid PV-wind turbine system for commercial buildings in Jordan

International Journal of Renewable Energy Research, 2017

The Middle East has about 45% of global crude oil and natural gas reserves, making it highly energy independent. However, not all countries in this region are endowed with such fossil fuel potentials. Jordan is one of such country with energy dependency of about 96%., On the other hand Jordan has huge renewable energy potentials which abound in the solar belt region with solar irradiance ranging between 4 kWh/m² and 7 kWh/m² and good wind potential with wind resources exceeding 7 m/s annually. Electricity tariff for commercial buildings is at $0.33 per kWh and with governments’ introduction of feed-in-tariff and net energy metering systems in December 2013, the potential of renewable energy systems looks promising for grid connected systems. This study simulates the potential of a stand-alone hybrid system comprising PV and wind turbine to adequately meet the annual electricity need of 34.4 MWh of a hotel in Jordan, the technical feasibility and economic viability of the system is a...
