The article is devoted to the study of the development of «green» energy in Ukraine. Extraction of non-renewable resources reduces our reserves, and using in the process of production and consumption leads to global warming. Further development of «green» energy will reduce the problems associated with environmental pollution and ensure consumer demand for clean energy at low prices. The article analyzes in details the current state of «green» energy of the country, considers promising opportunities for investment in the industry by Ukrainian and foreign entrepreneurs, which will create and implement new technologies in production, modernize obsolete enterprises. The main problems of using alternative energy sources are highlighted, the prospects for the development of «green» energy are determined, the possibilities and expediency of the transition to ecological types of energy are considered, taking into account the features of the country's economy. The article considers and analyzes the energy balance of the state, which is significantly dominated by the use of nuclear fuel, coal and gas. The use of modern and advanced technologies in the use of renewable energy sources will increase the share of clean energy in the energy balance of the country. The chronology of development of solar power plants in Ukraine is considered. It is noted that due to scientific and technological progress, reduction of prices for solar power plant equipment, «green» tariff capacity of generating alternative energy facilities will continue to grow. The volumes of energy production, which is produced with the help of renewable sources, are analyzed, the number of enterprises that receive income from the sale of electricity at the «green» tariff is considered. A comparative analysis of the size of the «green» tariff in Ukraine and European countries, the prospects for solving existing problems, proposed measures to fully disclose the potential use of alternative energy sources. The positive aspects of the use of alternative energy are analyzed; the role of the country in the process of implementing an effective energy strategy, creating an electricity market and the country's transition to a carbon-neutral economy is analyzed.

Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes. Many countries have made significant progress in the development of renewable energy.

The article examines a set of issues related to "green energy" in the world, problems and opportunities from the introduction of alternative energy sources for greening the economy, developing sustainable economy and preserving human potential. Analytical works of some Ukrainian authors have been studied, in which the current state, obstacles to the realization and prospects of "green energy" in the world have been determined. The purpose of the article is to refute the allegations about the need to immediately stop the introduction of "green technologies", including the construction of solar stations. There are two opposing views on the need for green energy, which have been being discussed around the world for the past few decades. The most popular evidence from both sides on this issue is given, in particular, that the planet can be saved only through the active use of renewable energy sources, and on the other hand, that "green energy" at the current level of human development will cause even more environmental and economic problems. The arguments most often expressed by opponents of the active introduction of "green energy" are highlighted, namely: the high cost of new technologies compared to existing types of generation; the inability of "green energy" to solve the problem of warming on the planet with reference to scientific research on the amount of CO2 emissions from different types of generation as a major factor in warming; danger to the energy systems of all countries of the world due to the instability of energy production by natural factors. Counter-arguments on these issues are provided and evidence of the ability and necessity to use clean technologies is provided. The problem, on which the opinions of both parties coincide, is highlighted - the reluctance of "green" investors to spend money on storage systems, energy storage and stabilization of energy systems due to their high cost, size, insufficient energy consumption and insufficient duration of work. It is noted that the issue of developing the latest energy storage and stabilization systems and their installation at new and existing RES stations needs to be addressed immediately, but is not an obstacle to the further development of green energy.

Technical Specifications

The use of alternative energy sources, in particular solar energy, has gained rapid growth in recent years. This trend is prompting manufacturers of equipment for solar power plants to increase production volumes. At the same time, the question arises of the disposal of used modules, because each material has its service life. According to technical specifications, the average life of solar modules and batteries is 25-30 years. Decommissioning may occur earlier than this time due to the following reasons – moral and physical deterioration, mechanical damage, replacement of obsolete equipment with new, modernization of solar power plants. Already in 2030, it will be necessary to replace the solar modules installed in 2000. Therefore, there are acute questions not only regarding the development of technologies for processing waste equipment from solar power plants but also organizational and economic methods. This article discusses the main problems that arise during the utilization and recycling of solar modules, analyzes the experience of countries in resolving these issues. After all, the use of renewable energy sources should minimize the negative impact on the environment from energy production at all stages – from the production of equipment for a power plant to the disposal and recycling of this equipment.

Bulk Power

Pollution and far-away location of generation are the main disadvantages regarding bulk power generation from conventional power plants like gas plants, thermal and nuclear power plants. These constraints give scope to look for alternative energy sources reducing pollution and distance of location. Distributed generation (DG) is a viable option to generate power at distribution level without pollution and further reducing transmission line losses due to distance. Sending power from renewable energy sources needs an inverter to be integrated with grid. Inverter also performs the task of harmonic filtering in source components acting as active power filter. This paper presents integration of distributed generation from PV array to grid via an inverter controlled with DG controlled PQ theory. When power is fed from distributed generation, the source power from main grid to load will decrease and this variation is shown in results. MATLAB/Simulink software was used to develop the proposed model and the results are discussed for different cases. Results are presented for two cases where the source current is affected by the load without APF and variable active power to grid with the integration of DG along with APF.
