Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

Subject. The article discusses the availability of technological equipment in the agriculture of the Republic of Dagestan. Objectives. We analyze the current situation and trends in the development of available technological equipment in the republican agriculture, identify the role and place of machine and tractor fleet in the retrofitting of the regional agriculture. Methods. The study is based on monographic, abstract logic, statistical, analytical methods. Results. Dagestan has got a critically few technological equipment, which affects the development of the regional agricultural sector. The availability of technological equipment is found to have dramatically reduced in animal husbandry for the recent 30 years. The availability of technological equipment and land cultivation strongly correlates, thus simplifying applicable agricultural technologies. Most agricultural producers of Dagestan were found to be unable to participate in the program for federal agricultural lease. Conclusions and Relevance. The deterioration of available technological equipment in agriculture is a key cause undermining the competitiveness of products and efficiency of the regional agriculture. We prove the importance of governmental actions incentivizing the influx of new technological equipment, including a set of measures reinforcing the availability of technological equipment. As long as most agricultural producers are microbusinesses that lack resources to participate in many machine renovation programs, funding should be increased substantially to subsidize a portion of equipment acquisition costs incurred by agricultural producers, and a portion of reimbursed costs as much as at least 50 percent of the value of agricultural machines acquired.

This paper presents a novel, scalable, and modular multiport power electronic topology for the integration of multiple resources. This converter is not only scalable in terms of the integration of multiple renewable energy resources (RES) and storage devices (SDs) but is also scalable in terms of output ports. Multiple dc outputs of a converter are designed to serve as input to the stacking modules (SMs) of the modular multilevel converter (MMC). The proposed multiport converter is bidirectional in nature and superior in terms of functionality in a way that a modular universal converter is responsible for the integration of multiple RES/SDs and regulates multiple dc output ports for SMs of MMC. All input ports can be easily integrated (and controlled), and output ports also can be controlled independently in response to any load variations. An isolated active half-bridge converter with multiple secondaries acts as a central hub for power processing with multiple renewable energy resources that are integrated at the primary side. To verify the proposed converter, a detailed design of the converter-based system is presented along with the proposed control algorithm for managing power on the individual component level. Additionally, different modes of power management (emulating the availability/variability of renewable energy sources (RES)) are exhibited and analyzed here. Finally, detailed simulation results are presented in detail for the validation of the proposed concepts and design process.

In this paper we analyze the impact of the renewable energy sources on the overall electric power system of the Republic of Macedonia. Specifically, the effect of the photovoltaic power plants is examined. For this purpose we developed an electricity production optimization model, based on standard network flow model. The renewable energy sources are included in the model of Macedonia based on hourly meteorological data. Electricity producers that exist in 2012 are included in the base scenario. Two more characteristic years are analyzed, i.e. 2015 and 2020. The electricity producers planned to be constructed in these two years (which include the renewable energy sources) are also included. The results show that the renewable energy sources introduce imbalance in the system when the minimum electricity production is higher than the electricity required by the consumers. But, in these critical situations the production from photovoltaic energy sources is zero, which means that they produce electricity during the peak load, and do not produce when the consumption is at minimum.

One of the most used renewable energy sources worldwide is geothermal energy. Itrepresents the heat, originated by natural processes happen in the Earth interior. The hot springsphenomena are the most frequent natural manifestation of geothermal activity.Geothermal potentiality of some area can be estimated based on geothermal gradient. Geothermalgradient is a conductive terrestrial parameter that represents the degree of increasing of the Earthtemperature vs. depth. It is usually expressed in ⁰C/m or ⁰C/km. Different areas have differentthermal gradients and thus different geothermal potential. Generally, higher geothermal gradientscorrespond to areas containing more geothermal energy.Geothermal characteristics of the territory of the Republic of Srpska are closely related to itscomplex geological setting. It is the reason why geothermal characteristics are different from areato area. Higher geothermal potentiality is recognised in the northern parts of the entity, in the firstorder in Semberija, Posavina and Banja Luka regions.The use of geothermal energy with different fluid temperatures can be considered throughthe Lindaldiagram, who firstly proposed acomprehensive scale with appropriate temperatures for differentuses. High temperature fluids are mostly used for electricity production and moderate and lowtemperature fluids for the direct use.Despite the fact that the territory of the Republic of Srpska hasfavourable geothermal properties, utilization of this kind of renewable energy resource isinadequate. Especially indicative are data about the use of geothermal energy by heat pumps (inbad sense) in comparison with praxis of developed countries.Chemical composition of thermal waters plays very important role and can be used in itsexploration stage, for analyses of possibility of its use and for prediction of exploitation effects, aswell. This kind of renewable energyresource, highly ecologically recommended, must be consideredmore seriously in the future in the Republic of Srpska. Furthermore, it must be put into the energystrategic documentsin appropriate manner.

It is emphasized that at the beginning of the XXI century application of cooperative lending experience of F.W. Raiffeisen cooperatives model in Ukrainian practice allowed credit unions to abandon collateral as the main form of credit security. For many small agricultural producers, especially farmers, signing of a group agreement on joint and several liability (formation of the so-called loan circle) was almost the only opportunity to obtain loans. The main reason for stopping this practice is indicated. It was caused by the consequences of the global financial and economic crisis, the first appearances of which have been felt in Ukrainian economy since 2008. It is discovered that the content of publications presented in scientific professional journals of Ukraine only to some extent reveals the essence of F.W. Raiffeisen approaches on lending to small rural producers. The need for in-depth study of such experiences is emphasized. It is proposed to establish rural credit societies in Ukraine, which are based on the experience of F.W. Raiffeisen credit cooperatives. The important role of state and local governments in the financial support of this process is emphasized. The external financing mechanism for such cooperatives, especially at the initial stage of their activity, with the use of F.W. Raiffeisen loan circles practice is described. Establishing rural credit societies to finance peasants and farmers are indicated as promising. A model of a rural credit society is proposed. It was successfully functioning in Germany, as well as on the territory of other European countries, including Ukrainian provinces, starting from the end of the 19th century. And provided that appropriate changes are made to current Ukrainian legislation, these rural credit societies can become a source of affordable loans for the development of farming. The expediency of detailing the proposed model of a credit cooperative is indicated, taking into account all the principles typical for cooperatives of F.W. Raiffeisen model.
