The role of the power supply device is to produce, process and distribute energy sources. Telecommunication equipment can only operate if it has continuous supply. Therefore, to maintain the continuity of the supply, a UPS (Uninterruptable Power Supply) device system is needed so that the supply to the Essential Load device will remain available so that continuity will be maintained. This research designs and proposes how a series of automatic redundant switch systems on UPS to ensure the availability of power supply for the main equipment of telecommunications systems. The Auto switch circuit is designed to have 3 (three) working stages which will trigger the relay driver as control circuit, namely the normal working condition of the contactor input K1 is present, the input condition is zero (lost), and the input condition is present. This system can automatically supply power to telecommunications equipment.

Fundamental Part

Energy storage systems are expected to play a fundamental part in the integration of increasing renewable energy sources into the electric system. They are already used in power plants for different purposes, such as absorbing the effect of intermittent energy sources or providing ancillary services. For this reason, it is imperative to research managing and sizing methods that make power plants with storage viable and profitable projects. In this paper, a managing method is presented, where particle swarm optimisation is used to reach maximum profits. This method is compared to expert systems, proving that the former achieves better results, while respecting similar rules. The paper further presents a sizing method which uses the previous one to make the power plant as profitable as possible. Finally, both methods are tested through simulations to show their potential.

Reducing Energy

Energy poverty is a problem that affects all member states of the European Union to a varying degree, including Poland, where about 9% of the population is at risk of energy poverty. The article aims to show the changes in energy poverty in Poland in 2010–2018. The specific goal, however, is to evaluate government measures aimed at reducing energy poverty through investments based on renewable energy sources. To present changes in the level of energy poverty in 2010–2018, the authors proposed a new synthetic measure that unifies several different measures used by researchers and allows for a comprehensive assessment of this phenomenon. The conducted research showed that in 2010–2018 there was a slow but visible decrease in the level of energy poverty in Poland. In addition, the article indicates investments in renewable energy sources that may have a positive impact on reducing the scale of energy poverty in Poland. The programs implemented with national and EU public funds, which finance investments in renewable energy sources in Poland, are also presented.

Regional Sustainable Development

In this paper, the author focuses on the fundamental hypothesis that the adoption of a concept of regional sustainable development and the use of renewable energy sources are preconditions to organising an acceptable regional tourism offering based on an eco-philosophy The renewable development of tourism regions is the basic framework for research regarding opportunities for introducing renewable energy sources such as hydro energy, wind power, solar energy, geothermal energy, and biomass energy. The purpose of this paper is to indicate the real opportunities that exist for substituting conventional energy sources with renewable ones and the role of renewables in regional development from economic, environmental and sociological viewpoints. It should also be noted that renewable energy sources have a strong regional importance and can contribute significantly to local employment.

The article examines topical problems of the role of international organizations in the direction of the development of alternative energy and strengthening of energy security in the world. Considerable attention is paid to the importance of the introduction and development of alternative energy in the context of ensuring environmental human rights and economic well-being. Analyzed the main international legal treaties regulating the reduction of greenhouse gas emissions into the atmosphere and the use of alternative renewable energy sources. The main international governmental and non-governmental organizations in the direction of ensuring environmental and energy security have been identified. Attention is drawn to the need to strengthen the role of these organizations by strengthening the functions of supervision and monitoring to increase the possibility of influencing states that do not comply with the provisions of signed and ratified international conventions. It is concluded that it is necessary to adjust the vector of development of instruments for the protection of environmental rights in the direction of its world globalization. The existing global concept for the development of alternative energy sources requires changes. Given that the environmental problem is universal and, although to one degree or another, it still affects every person, regardless of country or nationality, the obligation to protect the environment must be universal, fulfilled and enforced not only by the government bodies of sovereign states, but also international government organizations. It is noted that the programs and recommendations of international organizations are developed directly for individual states, taking into account their geographical and economic location when choosing the types and methods of developing alternative energy.

The paper studies the role of alternative and renewable energy sources (ARES) in the maintenance of Azerbaijan’s energy security. In the view of annual depletion of reserves capacity of such traditional natural resources as the oil, gas, coal, shale and the environmental disorder in their usage, as well as considering the fact of their implementation as the major pressure means serving to the geopolitical interests of the countries, due to the instability and variability of the fuel types prices in the world market, the necessity of surveying new alternative and renewable energy sources in the region is marked. It is pointed out that wide-scale recovery of alternative and renewable energy sources in Azerbaijan will lead to the involving of oil-gas raw into the petrochemical industry, to the decrease of degree of the harmful man-made effect on the environment in the process of energy production, as well as to the significant reduction of economic dependence on the various fuel types. The methods of increasing the production capacity of alternative energies in the strengthening of country’s energetic safety by the acceleration of implementation process of alternative and renewable energy sources were studied and the significance of the development of oil concept considered the essential of long-term maintenance of national energy safety marked as well.
