Abstract

In this paper, wind power potential of Mil-E Nader region is statistically analyzed based on 10 min measured short term wind data. Weibull parameters at 40 m height have been estimated and used to describe the distribution of wind data and its frequencies. Additionally, diurnal and monthly wind speed variations have been calculated. Based on power law model and average wind speed at three heights (10, 30 and 40 m), wind speeds at higher elevations have been extrapolated. Energy analysis has been carried out to find best hub height by comparing energy production of several wind turbines with different classes and hub heights. The energy production analysis showed that the wind turbines with 80 m height have high production in comparison to the others.

Introduction

Nowadays, scientists and the public are more concerned and sensitive to the need for environmental friendly energy sources. The energy demand is increasing continuously and the only way to fulfill this demand is to start using renewable energy sources. Wind is one of those major free, clean and inexhaustible renewable energy sources [1]. Wind is an abundant resource available in nature that could be utilized by mechanically converting wind power to electricity using wind turbines [2].

Technology of the extraction of power from wind with modern turbines is a well established industry, at present. Parameters such as improvement of wind farm efficiency as well as reducing wind turbine component costs, make wind power generation competitive to the conventional sources. Furthermore, the wind power has an additional advantage of being a non-polluting source of energy [3].

Preparing technical and economical feasibility study is a vital step before investing in a wind farm project. This study gives an outlook to investors about costs and economical aspects of a wind farm project. Accurate and proper information on a project conditions (such as site and wind characteristics) play a key role in wind farm feasibility studies. So, inappropriate information may lead to disinvestment and waste of money. In contrast with, select a suitable site for a wind turbine regarding to the parameters such as: turbine size, blade shape, capacity, etc. resulting in high efficiency of a wind farm. It is quite important to know several fundamental properties of the site such as wind behavior, availability, continuity, and probability in the proposed region. To make decisions with those properties, statistical and dynamic wind characteristics of the site should be found out using wind observations and statistical wind data [1].

This paper presents the detailed wind data analysis and wind availability at Mil-E Nader, an area in Sistan and Baluchestan Province of Iran.

Site description

Sistan and Baluchestan Province is one of the 31 provinces of Iran. It is in the southeast of the country, bordering Pakistan and Afghanistan and its capital is Zahedan (Fig. 1a). The province is subject to seasonal winds from different directions, the most important of which are the 120-day wind of Sistan known as Levar, the Qousse wind, the seventh (Gav-kosh) wind, the Nambi or south wind, the Hooshak wind, the humid and seasonal winds of the Indian Ocean, the North or (Gurich) wind and the

Wind speed data

The wind data used in this study were captured using a cup generator anemometer. The wind data were measured by 10 min sampling period at heights of 10, 30 and 40 m above ground level between years 2010–2012 (Fig. 2). The measurements include wind speed, wind direction, temperature, humidity and global radiation at the site. Technical specification of the mentioned sensors (using Theodor Friedrichs Company’s catalogues) is shown in Table 1.

Data logger device records minimum, average, maximum,

Methodology

Wind energy resource is highly variable both in space and time [7]. Therefore, to understand the characteristics of the resource, various parameters were considered.

Results and discussion

For the analysis of wind characteristics and wind energy potential of the Mil-E Nader region, the measurement data for the 18 months period from 01/09/2010 at 1:30 to 10/03/2012 at 9:00 have been used. Verifying measurement indicate that about 0.01% of the observation data (5 raw of observation data) were missing. These missing data were due to machine calibration, servicing and malfunction machine. Data for other periods were checked but unfortunately big gap for the sensor in 10 m height was

Conclusions

The investigations show that in the targeted Mil-E Nader region there is technically usable wind energy potential at 80 m hub height. The basic properties of the wind energy in the targeted region are:

1.
18 months average wind speeds at heights 10, 30 and 40 m are: 5.38 m/s, 6.84 m/s and m/s, 7.21 m/s respectively.
2.
The wind rose is characterized by two dominant wind directions at 30 and 60. These directions are similar to minimum turbulence directions and maximum wind power production directions so that

Spatiotemporal variation of power law exponent on the use of wind energy
2024, Applied Energy
The power law, a common method in wind energy assessments, often assumes a global power law exponent (α) of 1/7, potentially leading to inaccuracies in estimating wind conditions and energy potential. This study uses high-frequency measurements from eight wind towers to assess the power law's reliability and demonstrates its general applicability, except in complex topography. The α value is found to differ significantly from 1/7 in validation sites, yet it can be reliably used in ERA5 data based on regional verification. To evaluate the global spatiotemporal variation of α, we analyze the hourly α from 1980 to 2022 using ERA5 wind speed data at 10 m and 100 m. Our findings reveal varying α value with time and geography, with particular disparities between land and ocean. Additionally, we observe changes related to diurnal cycles, seasons, and latitudes. This analysis of α value carries significant implications for a global-scale wind energy resource assessment, site selection, and turbine design.
Estimation of regional and at-site quantiles of extreme winds under flood index procedure
2024, Heliyon
Extreme winds are becoming more common among environmental events with the most catastrophic societal consequences. A regional frequency analysis of Daily Annual Maximum Wind Speed (DAMWS) is necessary not only for a comprehensive understanding of wind hazards but also for infrastructure design and safety, wind energy potential, disaster risk reduction, insurance and risk assessment in a particular region of study. This study investigated regional frequency analysis of DAMWS of Baluchistan and Sindh provinces of Pakistan. L-moments regionalization techniques along with flood index procedure were applied to DAMWS records of 21 stations from 1990 to 2019 across the study area. We intended to find the regional frequency distribution for maximum winds and predict the returns for extreme winds events in the future. Only one station namely Lasbella was found to be discordant. With the help of cluster analysis, the remaining 20 stations were further divided into two homogeneous. Heterogeneity measures validate that both regions are homogenous with allotted stations. Regional quantiles for both regions are estimated through best-fit probability distribution among Generalized Normal (GNO), Generalized Logistic (GLO), Pearson Type 3 (P3), Generalized Pareto (GPA), and Generalized Extreme Value (GEV). Robustness of GLO distribution compared to GEV distribution is assessed through Monte Carlo simulations of relative bias and relative root mean square error. Findings clearly show that GLO distribution is the best for regional modeling. Furthermore, with the help of index flood procedure we determined at-site quantiles of all stations for various return periods. These estimated quantiles are of valuable information for various sectors, including infrastructure, energy, disaster management, and climate resilience, leading to improved planning, development, and risk reduction in the face of wind-related hazards in Sindh and Balochistan provinces of Pakistan.
Potential of wind energy and economic assessment in Egypt considering optimal hub height by equilibrium optimizer
2023, Ain Shams Engineering Journal
In Egypt, the wind market increases quickly to make it one of the top countries in the Middle East. This study discusses the viability of wind resources and the economic assessment for four locations in Egypt: Ras El-Hekma, Farafra, Nuweiba, and Aswan through two stages. In the first stage, the optimal hub height for some wind turbines has been calculated by using Equilibrium Optimizer (EO) algorithm to achieve maximum wind energy with overall minimum cost. The second stage, the economic assessment has been evaluated by using such turbines to calculate the cost of energy (COE) compared to the global and Egyptian production costs of wind energy. Developed MATLAB programs are applied for statistical analysis of wind data. The results have shown that Ras El-Hekma’s average wind speed is higher than other sites and its wind energy potential is the best. Moreover, the economic assessment for selected locations turns out that Ras El-Hekma by using EWT-DW61/22 turbine has the lowest COE.
Evolving from a hydrocarbon-based to a sustainable economy: Starting with a case study for Iran
2022, Renewable and Sustainable Energy Reviews
Environmental and socioeconomic challenges facing many hydrocarbon-rich nations could help them evolve from hydrocarbon-based (black) into renewables-based (green) economies. In this paper, we present a case study for application of this Black Into Green (BIG) method for Iran. We show that with international cooperation Iran could indefinitely meet its energy and freshwater needs by leveraging large-scale renewable energy harvesting systems integrated with seawater pumped storage hydropower, reverse osmosis desalination, and enhanced distribution systems. This BIG transition could be facilitated by allocating a significant portion of Iran’s potential hydrocarbon-based income to acquire, develop, and deploy renewable energy technology that utilizes Iran’s immense solar and wind energy potential. Our analysis shows that developing just 1% of identified sites would provide over 30 TWh of annual renewable electricity generation and storage, and 221 million m $^{3}$ /day of renewably-powered desalination capacity to meet the freshwater needs of over 85% of its population. In addition to providing renewable energy design and manufacturing technology, the international community could also work with Iran to help evolve its nuclear power program toward small modular reactors for baseload power generation. Such an arrangement would contribute to regional and global security, and greatly reduce the Middle East’s carbon emissions of which Iran is the largest emitter. Results from this holistic approach could then serve as a model for the world economy to work with other resource-rich nations to reduce their environmental impact while modernizing their economies and helping them achieve the socioeconomic goals outlined in the UN’s Brundtland report.
Reliability benefits of wide-area renewable energy planning across the Western United States
2021, Renewable Energy
In response to near- and long-term market and policy shifts, power systems are integrating increasingly-distant renewable energy resources. No analyses quantify the spatial heterogeneity of resource adequacy contributions of renewables at the interconnection-scale in the United States, which would indicate the value to resource adequacy of integrating increasingly-distant renewables. To fill this gap, we develop a Monte Carlo-based probabilistic reliability model to estimate the effective load carrying capability (ELCC) of wind or solar generators. We apply our model to estimate the ELCCs of new solar or wind generators at 1406 locations across the Western Interconnection when contributing to each of five power pools within the Interconnection. Across the five power pools, we find solar ELCCs range from 0% to 44% and wind ELCCs range from 0% to 55% across the Western Interconnection. Solar ELCCs increase from east to west for all but one power pool, incentivizing integration of western renewables into eastern power pools. Deploying storage with wind or solar generators increases their ELCCs, with larger increases occurring at locations with lower renewable-only ELCC values. Thus, resource adequacy gains from deploying storage with renewables can partly substitute for those from integrating increasingly-distant renewables.
A techno-economic analysis for power generation through wind energy: A case study of Pakistan
2021, Energy Reports
Pakistan needs to overcome the cost of power generation and the ever-increasing demand for energy with environment-friendly renewable energy resources. Several research efforts have been made with the support of Pakistan Meteorological Department in the last two decades for wind resource assessment (WRA) across the country. However, the practical installation of wind farms is quite a fraction of the total forecast wind energy potential. In this feasibility, WRA of Umerkot and Sujawal districts located in Sindh provinces of Pakistan has been analyzed by analyzing mean wind speeds, estimated Weibull parameters, power and energy densities calculation for various heights of selected wind turbines. Further, this paper analyzes the overall energy potential for these locations with implementation cost and pay-back period for investment. These locations are selected by the World Bank initiative of wind profiling campaigns to record wind speed data during 2016 and 2018 with 10 min resolution. It is observed that Umerkot and Sujawal sites are suitable for energy production. The highest values of power and energy densities for Sujawal are 414.18 W/m $^{2}$ and 3628.22 kWh/m $^{2} / Y r$ and for Umerkot these values are 303.86 W/m $^{2}$ and 2661.81 kWh/m $^{2}$ /Yr. The results indicate that using Nordex N90/2500 wind turbines are highly beneficial for Umerkot and Sujawal. The associated costs of energy are 0.074 $$$ /kWh and 0.056 $$$ kWh respectively and the payback period is estimated to be around 7 years with 20 years life time of the project. This work suggests the possibility of wind farm installation and commissioning based on power density calculation and cost of land acquisition. This work emphasizes the investment for wind farms at Sujawal and Umerkot for the sustainable growth of the country. This helps out policymakers for long term planning, development of wind energy projects and attracting investment for the country.
