“…Among these renewable energies, it can be seen that wind and solar energy are cited as the most commonly used [27,28], but hydropower is an important source of renewable energy as well, being the largest generator of electricity in the world. In addition to presenting an advanced technological development, hydropower presents many benefits [29,30].…”

Considering the importance of ISO 50001 in sustainable development, the objective of this research is to identify the challenges found by organizations during the implementation of ISO 50001:2011, according to the literature. To address this objective, a systematic search was conducted. Scientific papers from the following international databases were used: Science Direct, Emerald Insight, Scopus, Springer, Wiley, and Taylor and Francis. Permutations of the terms “ISO 50001” and “Challenges”, “Barriers”, “Lacks”, “Gaps”, “Obstacles”, “Problems”, and “Limitations” were searched. Following this strategy, 206 documents were found. After removing book chapters, articles from proceedings, duplicate articles, and articles that did not mention any challenge related to ISO 50001, 17 articles were left. Eleven challenges were found in these articles. The most cited challenges were: “Lack of Resources-Limitations (HR, Technologies, Infrastructure, Financial, Time)”, “Difficulty to determine the energy baseline and energy performance indicators”, “Human Resources deficiencies (competences, knowledges, and abilities)”, and “Lack of management support and/or commitment”. The challenges most cited shows the need for better planning before implementation as well as a comprehensive analysis of the organization’s requirements and features. The findings of this research show that this theme is still underexplored. The results presented can contribute to future industrial policies to potentialize countries’ economies.

“…PSH is currently the most common form of on-grid electricity storage, with an operating condition which is very well fitted to reversible turbomachines, namely Francis or pumps as turbines (PATs) [8]. The recent increasing influence of variable renewable energy sources forces innovations in energy storage technologies [9]. This has been the main motivation behind other PSH types, such as underwater PSH (UPSH), which some studies have shown can be competitive with conventional PSH and compressed air energy storage (CAES) systems.…”

“…This has been the main motivation behind other PSH types, such as underwater PSH (UPSH), which some studies have shown can be competitive with conventional PSH and compressed air energy storage (CAES) systems. In UPSH, seawater acts as an upper reservoir and an underwater tank has the role of a lower reservoir working with the same concept of a conventional PSH [9]. Accordingly, the novel renewable energies should be designed on the basis of new technologies and small decentralized hydropower plants to decrease the investment costs and increase the reliability and flexibility of the renewable source by making it less dependent on climate factors [10][11][12].…”

“…For this purpose, the pump as turbine (PAT) systems have been recently under consideration and increasing studies have come out addressing different aspects of that [14,15]. PATs are hydraulic pumps that operate in reverse mode for energy production purposes by means of a connected induction motor working as a generator [9]. The operational cost of a PAT is five to 10 times lower than that of a conventional turbine [16].…”

In recent years, interest has increased in new renewable energy solutions for climate change mitigation and increasing the efficiency and sustainability of water systems. Hydropower still has the biggest share due to its compatibility, reliability and flexibility. This study presents one such technology recently examined at Instituto Superior Técnico based on a transient-flow induced compressed air energy storage (TI-CAES) system, which takes advantage of a compressed air vessel (CAV). The CAV can produce extra required pressure head, by compressing air, to be used for either hydropower generation using a water turbine in a gravity system or to be exploited in a pumping system. The results show a controlled behaviour of the system in storing the pressure surge as compressed air inside a vessel. Considerable power values are achieved as well, while the input work is practically neglected. Higher power values are attained for bigger air volumes. The TI-CAES offers an efficient and flexible solution that can be exploited in exiting water systems without putting the system at risk. The induced transients in the compressed air allow a constant outflow discharge characteristic, making the energy storage available in the CAV to be used as a pump storage hydropower solution.

“…The increasing penetration of renewable energy sources (RES) in the power system has highlighted the benefits of being able to store energy in a more efficient manner, and the need of holding additional operating reserves to manage the system under more demanding conditions due to the inherent uncertainty and variability of wind and solar power [1,2].…”

The pumped storage hydropower systems are benefits for grid reliability and integration of variable renewable energy, in this context this paper presents the study and control strategy of a pumped storage hydropower (PSH) system based on permanent magnet synchronous machine (PMSM) associated to the renewable energy source. The dynamic behavior of a pump-turbine, including the PMSM with high number of poles, the AC/DC converter and the control of this system, is studied. Also, a control method of the PSH system, which consists of the reversible pump-turbine unit entrained by the PMSM, supplied of the variable power renewable energy source through a power electronic converter. Simulation results obtained on the basis of the dynamic models of the pumpturbine are given, for different operating points, to demonstrate the performance of the proposed system.
