“…The generation of electrical power by harnessing the weight of flowing or streaming water is known as hydropower, and the resulting hydroelectricity is known as hydroelectricity. It is anticipated to rise by roughly 3.1% annually for the next twenty-five years, making it the most commonly utilized source of renewable energy and responsible for 16% of worldwide power output (3,427 terawatthours of power generation in 2010) [13]. There are 150 nations that generate hydropower, with 32% of the world's hydropower coming from Asia and the Pacific in 2010.…”

Many nations must undergo economic growth, and this will inevitably lead to a rise in population, both of which will have consequences for the natural environment. This is due to the fact that producing energy (whether for electricity, cooling, heating or power for transportation motors and other applications) is an ecologically inefficient and wasteful activity that contributes to pollution. Considered crucial to the creation of prosperity, energy is widely recognized as an important factor in economic growth. It has a crucial role in alleviating poverty and fostering long-term growth. It has a beneficial impact on social, economic, and environmental development in areas such as livelihoods, water availability, agricultural production, health, population levels, educational equity, and addressing the needs of women and girls. Due to this, energy resources are crucial for every nation on Earth. This paper provides a discussion of the benefits to the economy, environmental effects (including on global warming), pros and cons, and methods for optimal utilization with regards to renewable energy sources and their role in sustainable development.

“…Power-electronic-based devices are expected to have a relevant impact on power system stability [13], for smalldisturbance [14][15][16][17] and large-disturbance phenomena [18]. Although it is clear that the main aplication of VSC-HVDC systems is power transmission, they can also help to improve the operation of power systems by means of supplementary controllers [19][20][21][22].…”

Multi‐terminal high‐voltage direct current technology based on voltage‐source converter stations (VSC‐MTDC) is expected to be one of the most important contributors to the future of electric power systems. In fact, among other features, it has already been shown how this technology can contribute to improve transient stability in power systems by the use of supplementary controllers. Along this line, this paper will investigate in detail how these supplementary controllers affect electromechanical oscillations, by means of small‐signal stability analysis. The paper analyses two control strategies based on the modulation of active‐power injections (P‐WAF) and reactive‐power injections (Q‐WAF) in the VSC stations which were presented in previous work. Both control strategies use global signals of the frequencies of the VSC‐MTDC system and they presented significant improvements on transient stability. The paper will provide guidelines for the design of these type of controllers to improve both large‐ and small‐disturbance angle stability. Small‐signal stability analysis (in Matlab) has been compared with non‐linear time domain simulation (in PSS/E) to confirm the results using CIGRE Nordic32A benchmark test system with a VSC‐MTDC system. The paper analyses the impact of the controller gains and communication latency on electromechanical‐oscillation damping. The main conclusion of the paper is that transient‐stability‐tailored supplementary controllers in VSC‐MTDC systems can be tuned to damp inter‐area oscillations too, maintaining their effectiveness.

“…After investigating several models, the work concluded that no single reducedorder model suits all scenarios. A model order reduction algorithm is developed in [32]. The proposed reducedorder model uses a state space method in an attempt to improve the model's accuracy compared to the existing models.…”

This paper presents a performance comparison between switching and reduced-order models of grid-following inverters. Different models have been developed to study the inverter’s operation using MATLAB and PSIM simulation tools. These models offer a tradeoff between accuracy and computational burden. The switching model fully represents the discontinuities in the inverter due to switching, but such a model demands high computational resources. The inverter representation is simplified using reduced-order models, which is common in the literature. However, the fidelity of these simplified models might not be adequate for some applications. Therefore, it is essential to investigate the performance of such models closely to ensure their suitability depending on the purpose of the analysis. Hence, a comparative study between switching and reduced-order models is presented here by simulating different scenarios and operation conditions. The results have validated the efficacy of the reduced-order model in representing the grid-following inverter’s operation in both steady state and response to a step change resulting from active or reactive power variation. Unlike the switching model, the findings illustrate that the reduced-order modeling fails to represent harmonics and losses. After simulating different scenarios, this work highlights the main differences between the switching and reduced-order models to facilitate the choice of the proper modeling method for researchers.
