AHP analysis used Expert Choice software to achieve the best criterion weights according to life cycle assessment results involving major criteria such as wind speed, slope, elevation, climate zone, air pressure and vicinity to infrastructure. The study further shows that the northwestern provinces, namely Kunduz, Balkh, Jawzjan, and Faryab, have the greatest potential in large wind power plants because of cost influences and wind speed. Altogether, these provinces would be expected to produce roughly 26.3 GWh of renewable energy per year, strongly supporting Afghanistan's renewable energy goals. On the low side, provinces like Badakhshan and Takhar have small sizing capacity with maximum suitability for localised and off-grid applications; Badakhshan has an area of 432 km<sup>2</sup> within a total of 2292 km<sup>2</sup>; Takhar has 217.7 km<sup>2</sup> and has limited potential for utility-scale connected wind farms. However, the GA method, which is known for its accuracy, supports the AHP result for Badakhshan but depicts lower suitability for Takhar. The GA unequivocally points out Kunduz medium-suitable areas and sporadic potentiality levels in Samangan and Baghlan Province. A total of 918 km<sup>2</sup> of the Kunduz area is potential, while 854 km<sup>2</sup> are moderately potential for wind energy. The province of Sar-e-Pul has identified the Southern region as a potential wind energy source-524 km<sup>2</sup>. In total, 1816 km<sup>2</sup> provinces of Balkh and Jawzjan together have the largest wind energy potential of about 14.3 GWh per annum. Combined with the estimate, the total harvestable wind energy in the study area is 46.6 GWh. The results of this paper are important for policymakers and stakeholders to select appropriate sites for wind farm development, promote the sustainable energy agenda, and meet the increasing energy demands in Afghanistan.</p>","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.70032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing the limitations of these methods, such as local optimality and constraint violations, is achieved through intensive experimentation, utilising stochastic initialisation and a hybrid heuristic-GD multiple-run strategy. These experiments also investigate the effects of heuristic algorithm parameter settings on the optimisation results, identify optimal parameters for each heuristic-GD method, and assess their effectiveness in handling uncertainties in CEVB operational model inputs (solar irradiance, electricity price, and electric vehicle [EV] power demand). Evaluations conducted using actual operational data from an EV charging station in South Australia demonstrate that all proposed methods can achieve global optimal results in fewer than 100 runs with appropriate parameter settings. Scalability tests were conducted to validate the method's feasibility for larger systems, offering valuable insights into computation times as the number of CEVBs grows.

In this context, several economic indicators usually considered in energy industry, such as LCOE (levelized cost of energy) will be calculated. The method was carried out for a floating offshore wind farm composed by semisubmersible substructures and located in the main Atlantic Islands of Spain: the Canary Islands. Moreover, several cases of study with different prices of steel have been calculated in order to know the influence of this parameter in the economics of an offshore wind farm. Results of the three cases of study considered the highest economic variations are related to the internal rate of return and LCOE, with values of −7.6% and 5.4% respectively.

The impedance mismatch will reduce the coupling efficiency and transmission efficiency of signals, and seriously affect the quality of power line communication. Therefore, accurate measurement of power line channel impedance and analysis of impedance characteristics are of great significance for improving the reliability of power line communication. In this paper, an improved ratio method considering the noise interference is proposed. In the method, the original generation method of sweep frequency signals is changed to one-time multi frequency and variable amplitude injection signals. Based on real-time signal processing technology, the voltage information at all tested frequency points is measured at once, including amplitude and phase. Through digital signal processing technology, the influence of noise is weakened, and the impedance amplitude and phase of all tested frequency points are accurately calculated. By the method, the requirements of the measurement circuit are simplified and the frequency range of impedance measurement is expanded to 100 kHz to 12 MHz.

Current research faces several challenges: traditional methods fail to fully consider the uncertainty of line repair time, existing robust optimization methods encounter difficulties in solving problems involving mobile energy storage (ME), and simple symmetric intervals cannot accurately describe the uncertainty of repair time. To address these challenges, this paper proposes a two-stage distributionally robust post-disaster recovery model that optimizes the connection location of ME in the first stage and adjusts the output of resources such as ME in the second stage to minimize load loss. A Weibull distribution is introduced to fit the repair time of damaged lines, while confidence intervals replace simple symmetric fluctuation intervals to handle the uncertainty of line repair time, improving prediction credibility. The column and constraint generation algorithm is applied to decompose and solve the model.

Traditional PV control typically relies on maximum power point tracking (MPPT); however, in MPPT mode, PVs cannot contribute to frequency control. By implementing droop control on PVs, it becomes feasible for them to participate in frequency regulation. This research introduces a dual droop control approach that focuses on both slow and fast frequency responses to ensure frequency stability and provide a fast response to frequency deviations. Additionally, an adaptive droop coefficient (ADC) is introduced via a fuzzy logic controller, which is incorporated into the dual droop control system to enhance its effectiveness. The ADC provides more flexibility for PVs by providing an appropriate coefficient based on frequency conditions during both fast and slow frequency responses. Additionally, the power from the PV systems is divided into two components: the usable maximum power point and the stored power. Suitable algorithms are presented to facilitate the participation of these two active power components in achieving power balance. This approach enables the control system to maintain active power balance in response to sudden changes for effective frequency control.

The proposed hierarchical cyber insurance planning model (HCIPM) offers an integrated approach to managing the dual challenges of financial risk and operational disruptions caused by sophisticated cyber-attacks. The model is built upon a two-stage hierarchical optimization framework: the first stage determines the optimal allocation of cyber insurance to minimize costs while ensuring adequate risk coverage, and the second stage focuses on real-time operational defense strategies, such as load shedding and resource management, to mitigate the impact of cyber incidents. A key innovation of the HCIPM is its incorporation of a distributionally robust optimization (DRO) methodology, combined with Conditional Value at Risk (CVaR), to effectively handle the uncertainties inherent in FDI attack scenarios. By representing extreme events and their probabilities, this framework ensures robust decision-making under high uncertainty. Extensive simulations conducted on a 33-20 node distribution system demonstrate the efficacy of the proposed model. Results indicate that the HCIPM achieves a 35% reduction in load shedding costs and a 28% improvement in resilience metrics, such as system recovery time and operational continuity, compared to traditional approaches. Additionally, the model demonstrates a significant decrease in financial losses attributable to cyber-attacks, with a 40% reduction in economic damages across high-risk scenarios. The findings underline the model's capability to not only reduce operational costs but also enhance system stability and resilience under diverse attack scenarios. By integrating financial mechanisms such as cyber insurance with technical defenses, the HCIPM represents a comprehensive solution for managing cyber risks in critical infrastructure. This research bridges the gap between operational resilience and financial protection, offering a pioneering framework for future applications of cyber insurance in power systems and other critical infrastructures. The proposed model provides a scalable and adaptable strategy, making it an invaluable tool for utilities and policymakers in their efforts to safeguard modern energy systems against evolving cyber threats.</p>","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143535995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
