Renewable energy (RE) is currently viewed as a planned and effective option to achieve development sustainability, as it provides an appropriate answer to climate change and also meets the power requirements. With regards to the current scenario in Iraq, a grave deficit with regards to electric power has been looming in the country and this serious shortage in equipped power started decades ago. Various prospects exist regarding the adoption of renewable energy in order to deal with the current issue pertaining to power shortage. This present study is a crucial examination of the existing and future electrical power needs in Iraq and the ongoing planning and challenges that are deliberated, for a better understanding of the prospects of utilizing Renewable energy sources for investment as well as to be able to provide energy to all those who need it in Iraq. Hopefully, this study can support researchers in earning an in-depth understanding of previous research efforts on this subject, and in exploring directions for future research.

“…Additionally, the offshore wind climate does not vary considerably with height, and offshore winds are more consistent and predictable than onshore winds, reducing the level of wind power intermittency to some extent. In 2019, Belgium's capacity factors for onshore wind turbines were 30%, nearly half of the capacity factors for offshore wind turbines, which were 53% [2]. However, offshore wind power is currently concentrated in one region, increasing up and down ramp rates, while the wide geographic spread of onshore wind capacity enables the reduction of the aggregate wind power variability, which is referred to as the 'smoothing effect', as wind speeds experienced in different areas are not 100% correlated over time [79].…”

“…The inherent variability and uncertainty of wind power generation need improved power system flexibility [1] [2], which can be enhanced in a variety of ways, including an estimate of the additional reserve capacity required as the variable renewable generation (VRG) expands [3] [4]. In [5] [6], as wind power penetration rises, reserve requirements rise as well, and in [7] [8], additional reserve requirements increase linearly with this rise.…”

“…4, December 2023: 945 -966 946 ranges, whilst wind variations vary with seasons, and times of the day [14], therefore further data would contain additional information and could produce different ranges [15]. The investigation of increasing shares of variable RG on the characteristics of power ramping has been discussed in [16] [17] through statistical analysis of historical data. In [18] [19], new metrics have been introduced for understanding the characteristics of power ramping.…”

The need to deal with variability in wind power output is one of the greatest challenges connected with adopting a considerable amount of wind power into power grids. Power system operators need to acquire more information on this variability, which can be utilized in the mitigation of high ramping events, especially when these events synchronize with a large error in the prediction, ensuring flexibility and reliability in the power system besides the economic considerations. The paper analyses short-term variability in output power using actual data obtained from aggregated wind farms from 2015 to 2020, where power ramping characteristics are described using a variety of measurements. The use of the standard deviation of short-term wind power variation as a reserve measure will be investigated in detail since there is no consensus about the ideal confidence level value as a multiplier of σ, which ranges from 3 to 6 times σ. The paper addresses how large this confidence level should be, as well as developing a data-driven approach for estimating this reserve with increasing wind shares and evaluating the proper distribution of short-term wind variation. The results illustrate that the stochastic variations in wind power can retain many of their characteristics from year to year, even when the share of wind capacity is raised.
