“…Seven parameters were selected for the research, which are most important for the characteristics of energy storage devices and are most often found in the literature. These are output power, capacity, efficiency, response time, discharge time at rated power, service life and unit cost [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”

“…When energy decreases (for example, during peak hours) or it is off, previously accumulated energy can be used. This means that renewable energy sources require the use of energy storages along with them [9][10][11][12][13][14][15][16][17][18][19][20].…”

“…They are of different types and differ sharply from each other in terms of the principle of operation, device, technical capabilities and financial costs. Along with all this, there is no doubt that the need for the use of energy storages will arise and increase as the transition to the widespread use of renewable energy around the world [9][10][11][12][13][14][15][16][17][18][19][20].…”

Research relevance This article presents a mathematical solution to the issue of a comparative analysis of various types of energy storage devices and determining the most efficient type of energy storage device for use on an industrial scale. The subject of the study in the article is the most important parameters of seven types of energy storages, the use of which is spreading in the world. The purpose of the work is to obtain an answer to the following question: which of the ubiquitous different types of energy storages is most likely to be the most efficient for the future industrial energy supply? The following tasks are solved in the article: 1) generalization of the collected data; 2) analysis (evaluation) of data using mathematical methods of data analysis. The following research methods are used: comparison, abstraction, axiomatic, analysis, synthesis, formalization and induction. The following results were obtained: among the analyzed energy storages, the best result was shown by a mechanical potential (gravitational) energy storage. Conclusions: If it is planned to use energy storages on an industrial scale in various fields, it should be recognized as expedient to give preference to gravitational devices.

The integrated OWC-PON architecture has a potential to overcome the limitations of existent RF technology and eliminate the last mile bottleneck in geographically constrained access networks thus providing real sense broadband from core to user. However, phenomenon such as atmospheric turbulence causes performance degradation in such systems. In the dissemination of multimedia services, the performance is the ultimate quality as perceived by end user's visual senses. To ascertain this quality in quantitative terms, full reference quality metrics are employed for communication purposes. This paper deals with classification, evaluation and analysis of various image quality assessment metrics for image transmission over OWC channel under varying turbulent conditions. The performance enhancement in terms of these metrics is investigated by deploying MIMO diversity reception. Moreover, a prediction model for SSIM is developed and compared for both SISO and MIMO links. The results show an improvement in IQA metrics with diversity reception. SSIM can be predicted in terms of log of refractive index structure parameter by a fourth order polynomial model for both SISO and MIMO receptions under all regimes of turbulence. The goodness of the fit statistics is presented along with the models to provide for their accuracy and reliability.
