Multi-rope elevators are widely used in modern buildings. However, problems such as vibration, noise, uneven wear of key components and shortened life caused by the uneven distribution of rope tensions are still unsolved in the elevator industry. In order to balance the different tensions and the axial deformation of each rope, a novel automatic balance equipment for rope-type elevators (NABE-RE) is proposed in this article. Simulations based on the Simscape numerical methodology are used to verify the kinematic rationality of the proposed mechanism. The optimal structural stability of the core components is evaluated through a series of investigations based on the finite element method. Additionally, the manufactured prototypes are put through a series of comparison experiments to evaluate their tension balancing performance. The results show that the unbalance rate of the system is effectively limited to a low level, thus verifying the feasibility of the automatic tension balancing function of the proposed NABE-RE.

“…Energy sources that have the highest potential can be prioritized for further development. This potential can be developed and maximized by using technologies that have been developed by researchers, for example, triboelectric nanogenerators for ocean waves (Huang et al, 2020;Rodrigues et al, 2020;Zhang et al, 2019), piezoelectric systems for hydro, micro-hydo, pico-hydro (Bao et al, 2019;Mahajan et al, 2021;; tidal-current turbine for tidal energy (Mutsuda et al, 2019;Li & Zhu, 2023;Qin et al, 2022), binary cycle power plant for geothermal (Eskandari, 2023;Hekim & Çetin, 2021;Wu & Wang, 2022), biorefinery for biomass (Kosamia et al, 2022;Saravanan et al, 2023;Siddiki et al, 2022), anaerobic digestion for biogas (Kannah et al, 2021;Vargas-Estrada et al, 2021;, hybrid photovoltaic for solar (Gupta et al, 2021;Tang et al, 2023;, and triboelectric nanogenerator for wind (He et al, 2022;Li et al, 2021;Ren et al, 2022). The rapid pace of technology is increasingly enabling humans to process renewable energy effectively.…”

This study aims to reveal the various renewable energy sources that have the potential to be developed on the island of Java, Indonesia. Because it is cheap and easy to reach, non-renewable energy is widely used as a source of energy for people's lives. The negative side of non-renewable energy sources forces local governments to look for alternative energy sources that are more environmentally friendly. Environmentally friendly alternative energy is rarely studied, specifically on the island of Java, through literature studies. Therefore, this study used a research method: a literature study on 28 Scopus, WoS, and Sinta-indexed articles. This literature study yields the information that 10 types of renewable energy sources have the potential to be developed in Java. These renewable energy sources can be further developed using technology according to their potential in each province. Thus, this research has succeeded in linking various renewable energy sources that have the potential to be developed on the island of Java.

“…The tidal current energy is a kind of energy that changes with time and space, which determines that the power has unpredictable fluctuation. With large-scale power current power generation connected to the grid, the negative impact of power fluctuation on the grid operation becomes more apparent [2]. Therefore, mining the essential attributes of tidal current power fluctuation can minimize the risks on grid operation.…”

With the continuous maturity of tidal current power generation technology, the scientific requirements for testing and evaluation are also increasing. In the process of analyzing the measured power data of tidal current power generation, the selection of sampling interval has a significant impact on the accuracy of power fluctuation analysis. Choosing an appropriate sampling interval can reduce data processing and improve calculation speed while ensuring the accuracy of test data. Based on the measured power data of tidal current power generation in a certain sea area of China during rising and falling tides, this paper calculated and analyzed the power fluctuation of multiple sampling intervals through discrete index analysis and first-order difference component analysis. And based on the entropy weight method, obtained the regularity of power fluctuation with sampling interval, calculated the comprehensive fluctuation coefficient to determine the maximum sampling interval, and proposed a recommended sampling interval of 60 seconds. This has important practical significance for scientifically testing tidal current power generation.
