Techno‐economic evaluation of standalone hybrid solar‐wind systems for small residential districts in the central desert of Iran

Abstract

Today, it is common knowledge that increased use of renewable energies has a significant impact on reducing greenhouse gas emissions. The most notable types of renewable energies are solar energy and wind energy, whose popularity comes from their prominent features such as cost‐effectiveness, stability and easy utilization. The objective of this paper is to perform a technical–economic analysis on combined utilization of solar and wind power in two cities of Qom and Yazd, to conduct a feasibility study on the construction of clean energy producing power plants in these locations. To achieve this objective, we first gather the required data from the national meteorological organization, and then use Homer software to perform technical and economic analyses on the two considered sites. Solar and wind analyses on Qom and Yazd show that both cities have great potential in solar energy generation, but wind speed data indicate that only Qom has the wind characteristics appropriate for wind power generation. Overall, these results indicate that investments on solar energy sector of both cities will be economically justified, but only Qom has the wind characteristics required to make investments on its wind energy sector economic. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1194–1207, 2017

The Role of Renewable Energy to Achieve Energy Sustainability in Iran. An Economic and Technical Analysis of the Hybrid Power System

“…Among renewable energies, the role of wind and solar energy is most remarkable for electrical production [40]. Because wind speed and solar radiation especially in the countries with proper potential in this regard are an effective factor to more exploitation of renewable energy and electrical production [34].…”

“…More than two-thirds of Iran experience about 300 sunny days per year and average solar radiation of Iran is about 4.5-5.5 kw/m 2 per day, which points to a very high solar energy generation potential [20]. For example it can be mentioned that some of cities in Iran such as, Yazd [34], Taleghan, Abadan, Bandar-Abbas, Semnan [2], Kashan [33] has a good potential in solar energy. Also Iran country for good weather condition is suitable for wind energy utilization, and the abundance of windy areas in Iran provides it with a suitable platform to extend the development of wind farms.…”

Feasibility Study of a Grid‐Tied Photovoltaic System for Household in Pakistan: Considering an Unreliable Electric Grid

“…Razmjoo et al . performed technical–economic analysis of a solar and wind hybrid power in two cities of Qom and Yazd and found that the investments on renewable energy sector of both cities will be of economically justified.…”

“…The proposed energy system is able to meet 67.3 and 62.3% load demand using renewable sources, which helps to reduce the GHG (greenhouse gas) emission by 67 and 64% for the two islands. Razmjoo et al [21] performed technical-economic analysis of a solar and wind hybrid power in two cities of Qom and Yazd and found that the investments on renewable energy sector of both cities will be of economically justified.…”

Simultaneous feasible injectivity of foam and hydrolyzed polyacrylamide to optimize the oil recovery enhancement

“…Although both mechanisms are within the mechanism of capillary pressure, capillary adsorption utterly depends on the surfactant formulation in comparison to the capillary snap-off. Two-dimensional presentation of foam system are being graphically depicted in Figure 1 (Jones et al, 2016a(Jones et al, , 2016bKapetas et al, 2016Kapetas et al, , 2017Khoshnevis et al, 2017;Li et al, 2006;Razmjoo et al, 2017).…”
