“…In conclusion, the REI's mean‐median and range values are very different. Since the standard deviation is higher as a result of this more considerable difference (2.29E+08), this suggests that the REI swings with time (Wang et al, 2023). Since this prevents us from making predictions about the variable, we must go deeper into the matter.…”

Energy resources' impact on gross domestic product and financial growth is controversial. The research is quiet on the potential effects of fluctuation in other areas, such as energy resource investment and finance, on exchange rates, financial and environmental indicators, making it urgent that this topic receives attention today. Our research aims to fill this gap by highlighting the fundamental insecurity of natural resource markets, energy expenditure markets and green financing markets. Because of the challenges in collecting older data, this analysis focuses on the decade from 1990 to 2020. We analysed the following asymmetry by employing the model TGARCH specification. According to the calculations, there is more room for fluctuation after a negative shock to natural resources than after a positive one. The study's empirical findings are then used to inform policy recommendations for maintaining a secure financial system and controlling the rising cost of scarce natural resources. The study also highlights the need for increased investment in green finance and recommends diversifying existing energy resource investments to foster the growth of alternative energy sources. This research suggests that we put more resources into green financing and develop new renewable energy sources. Conclusions: natural resource and energy investments are subject to volatility over time, as evidenced by the results and standard and relevant volatility assessments such as autoregressive conditional heteroscedasticity.

“…Furthermore, validation on real electrical-network models shows substantial improvements in accuracy and robustness compared to traditional methods. Another study [73] proposes a network-reduction methodology based on the generalized Thevenin theorem, addressing optimization and reorganization of existing networks by connecting subnetworks. The research emphasizes the importance of considering uncertainties in the reconfiguration of distribution networks to enhance their robustness and operational efficiency.…”

This paper provides a thorough exploration of the evolution and contemporary trends in electrical-distribution networks, with a focus on smart grids in the context of Industry 4.0. Beginning with the traditional components of electrical grids, the study highlights the transition towards sustainable energy sources and the integration of renewables. Key trends include economic operation, the application of distributed energy resources, and the significance of photovoltaic solar energy. The paper unfolds in seven sections, examining smart-electrical-network architecture, sustainable technology progression, energy efficiency, carbon-emission-reduction challenges, future perspectives, and concluding insights. Each section delves into specific layers and aspects, such as data management, electrical infrastructure, automation, and consumer interaction. The intricate role of smart meters and their impact on energy management is explored, providing a comprehensive overview of the current state and future directions of electrical-distribution networks.

“…Regarding structure, the growing utilization of renewable energy makes the system's power structure more complicated, which might pose greater running risks; the elevated use of renewable energy will raise the network's rate of interruption and increase the susceptibility of the power grid to risks.

The primary goal of electricity producers is to ensure the efficient operation of the electrical grid and the reliable delivery of electricity to individual households. Strengthening the electricity network with the integration of micro-power plants such as wind farms and photovoltaic power plants, as in the case of Algeria, contributes to improving the quality of electricity supplied to consumers. This work presents a simulation study of the electrical network of the Adrar region using ETAP program, to show the influence of the insertion of photovoltaic and wind power plants on the electrical network. The results showed good tolerance of the grid to the integration of wind energy, while the integration of photovoltaic energy needs more requirements and technical challenges to overcome, because, as shown by the results of simulations, the integration of photovoltaic energy makes the network more vulnerable to disturbances. The primary reason for this phenomenon is the lack of mechanical inertia, enabling the system to minimize perturbations. Where wind turbines are unique in their ability to withstand load variations and respond quickly to disruptions. They return to their initial value in 20 seconds, while solar power systems signal return to their initial value after 45 seconds due to their lack of mechanical inertia. Owing to the limitations of the electrical network, the majority of test scenarios demonstrate that wind farm structures can sustain a steady voltage and frequency of 50 Hz. On the other hand, there are momentary fluctuations in voltage and frequency in structures that have photovoltaic systems installed.
