The Impact

Paper is characterized by scientific novelty as it involves a very scarce research problem in Lithuanian‘s energy sector, assessing the impact of renewable energy resources on the energy economy. Renewable energy sources have a multiplier effect in spurring the economy and the development of not only the energy sector but also all the supporting activities related to such industry. The impact of the development of renewable energy is one of the factors that develop the quality of technology innovation development. This study includes the impact of renewable energy on the energy economy, using multiple linear regression models. The results of the study have shown that renewable energy resources: wind, sun, water, geothermal and biomass can not always be used together because they compete with each other and therefore reduce the efficiency of the energy economy. In this context, three combinations of renewable energy resources have been developed, which have been adapted to assess the impact of the energy economy on energy productivity and energy intensity. It has been found that the combination of resources of the second model (M2) RE is significant for the efficiency of the energy economy.Keywords: Renewable energy resources; Energy economy; Impact of efficiency

Renewable energy sources are abundantly available in Africa due to the continent’s geographical location. For example, it is the sunniest continent on earth with about 85% of the landscape having solar insolation of approximately 2000 kWh/m2 in a year and also with a large stretch of coastline where both wind and wave energy resources are abundant. The available renewable energy sources are underutilised due to many challenges such as inadequate funds, bad or nonexistent policies, and unavailability of skilled labour. This paper, therefore, aims to investigate the impact of renewable energy on Africa and the world as a whole if these renewables are utilised efficiently. The paper again will look into the reasons why renewable energies in Africa are underutilised and recommend possible solutions to these problems as well. Moreover, the paper will discuss the social, economic and environmental impacts of utilising renewable energy in Africa regarding jobs creation, infrastructure development, revenue creation, and reduction of carbon emissions into the atmosphere. The efficient utilization of these renewable energy resources will make Africa a powerhouse of clean energy production for its use and export.

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.

Abstract Renewable-energy resources require overwhelming adoption by the common masses for safeguarding the environment from pollution. In this context, the prosumer is an important emerging concept. A prosumer in simple terms is the one who consumes as well as produces electricity and sells it either to the grid or to a neighbour. In the present scenario, peer-to-peer (P2P) energy trading is gaining momentum as a new vista of research that is viewed as a possible way for prosumers to sell energy to neighbours. Enabling P2P energy trading is the only method of making renewable-energy sources popular among the common masses. For making P2P energy trading successful, blockchain technology is sparking considerable interest among researchers. Combined with smart contracts, a blockchain provides secure tamper-proof records of transactions that are recorded in distributed ledgers that are immutable. This paper explores, using a thorough review of recently published research work, how the existing power sector is reshaping in the direction of P2P energy trading with the application of blockchain technology. Various challenges that are being faced by researchers in the implementation of blockchain technology in the energy sector are discussed. Further, this paper presents different start-ups that have emerged in the energy-sector domain that are using blockchain technology. To give insight into the application of blockchain technology in the energy sector, a case of the application of blockchain technology in P2P trading in electrical-vehicle charging is discussed. At the end, some possible areas of research in the application of blockchain technology in the energy sector are discussed.

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.

The Impact

The continuous increase on the penetration levels of Renewable Energy Sources (RESs) in power systems has led to radical changes on the design, operation, and control of the electrical network. This paper investigates the influence of these changes on the operation of a transmission network by developing a set of indices, spanning from power losses to GHG emissions reduction. These indices are attempting to quantify any impacts therefore providing a tool for assessing the RES penetration in transmission networks, mainly for isolated systems. These individual indices are assigned an analogous weight and are mingled to provide a single multiobjective index that performs a final evaluation. These indices are used to evaluate the impact of the integration of RES into the classic WSCC 3-machine, 9-bus transmission network.

The main objective of the work is to develop principles for the formation of the optimal composition of the energy complex from all the given power plants based on renewable energy sources for an autonomous consumer, taking into account the variable energy loads of the consumer, changing climatic conditions and the possibility of using local fuel and energy resources. As a result of solving this optimization problem, in addition to the optimal configuration of the power complex, it is also necessary to solve the problem of optimizing the joint operation of different types of power plants from the selected optimal configuration, that is, it is necessary to determine the optimal modes of operation of power plants and the optimal share of their participation in providing consumers at every moment in time. A numerical method for analyzing and optimizing the parameters and operating mode of the energy complex with the most accurate consideration of the schedule of changes in consumer load and software that automates the solution of this optimization problem are also presented.
