Primary Energy Supply

The study analyzes the economics of renewable energy sources into electricity generation in Tanzania. Business as usual (BAU) scenario and renewable energy (RE) scenario which enforce a mandatory penetration of renewable energy sources shares into electricity generations were analyzed. The results show total investment cost for the BAU scenario is much lower as compared to RE scenario while operating and maintenance variable costs are higher in BAU scenario. Primary energy supply in BAU scenario is higher tied with less investment costs as compared to RE scenario. Furthermore, the share of renewable energy sources in BAU scenario is insignificant as compared to RE scenario due to mandatory penetration policy imposed. Analysis concludes that there are much higher investments costs in RE scenario accompanied with less operating and variable costs and lower primary energy supply. Sensitivity analysis carried out suggests that regardless of changes in investments cost of coal and CCGT power plants, the penetration of renewable energy technologies was still insignificant. Notwithstanding the weaknesses of renewable energy technologies in terms of the associated higher investments costs, an interesting result is that it is possible to meet future electricity demand based on domestic resources including renewables.

Depth Analysis

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

Energy Supply Security

Electricity generation, one of the renewable energy sources (RES), delivers a solution for various problems such as energy efficiency, energy supply security, reducing foreign dependency, and especially, environmental concerns. However, the solutions provided for these problems bring along the question of which RESs are produced more effectively. Therefore, in this research, RESs used for electricity generation in Turkey were analyzed by using generation data to show which one is more effective. Bi-objective multiple-criteria data envelopment analysis (BiO-MCDEA) method, a goal programming-based efficiency determination method, was used for the efficiency analysis conducted for five years between the years of 2014 and 2018. As a result of the analysis, geothermal energy came into prominence as the most effective RES for all of the years included in the solution. Geothermal energy was followed by biomass energy, wind energy, hydroelectric, and solar energy, respectively.

Energy Supply Systems

Currently, the majority of world economies (even those located in the sunbelt (+/− 35 degrees of latitude with good sunshine with low seasonality) uses various types of fossil fuels as the main source of energy for their economies. However, this represents a very volatile and unsustainable strategy, since according to various estimates, the fossil fuel era will inevitably end as all carbon fuels are going to be spent in the next few centuries. Unlike traditional energy, renewable energy sources (RES) are not based on energy resources, but rather rely upon natural energy flows. With regard to its unique property, there has been an active construction of power plants of renewable energy and their gradual integration into national energy supply systems in recent decades. At the same time, the existing models of electricity markets were unprepared for their wide distribution. Hence, determination of the market value of energy generated by power plants using renewable energy sources becomes a particularly significant issue. This market value has to take into account the prevention of costs from the use of fossil fuels, as well as the resulting environmental benefits. Our paper proposes methods for solving this problem, contributing to the increase of economic efficiency of investment projects for the construction of renewable energy facilities and the formation of economic incentives for their propagation in energy supply systems. The proposed methods are based on the dynamic differentiation of tariffs for consumers with renewable energy sources depending on their structure of electricity consumption. Its effectiveness is demonstrated by calculating the cost of electricity for households located in the Krasnodar region using renewable energy sources. It is shown that this approach to the formation of tariffs for consumers allows the household to receive additional savings from the efficient use of energy installations on RES and energy storage devices in terms of alignment of the energy consumption schedule. This creates a significant incentive for households to use them and contributes to increasing the effectiveness of government renewable energy support programs, including by solving the acute problem of raising electricity tariffs from the grid.

The relevance of the transition from traditional to renewable energy sources is investigated in the paper. The most popular renewable energy sources (RES) for Ukraine and the World are highlighted. The trend of changing electricity generation by photovoltaic stations is analyzed. Peculiarities of the functioning of electric networks with RES are considered. A mathematical model of the problem of optimal control of the parameters of the normal mode of the power system (PS) with a high level of integration of photovoltaic power plants (PPS) is presented. The main components of the criterion of optimality in the control of the power system, which must be taken into account when determining it. The article investigates in more detail such a component of the optimality criterion as power equivalent to the loss due to power failure caused by unstable generation. The instability of RES generation, in particular, FES, can be caused by both unpredictable changes in meteorological factors and changes in the technical condition of FES equipment. The photovoltaic module is the main element of any FES, so the article focuses on determining the technical condition of the FEM. Therefore, the main study presented in the article is the development of a neuro-fuzzy model to determine the technical condition of the FEM, which is represented by the coefficient of the total residual resource. For this purpose, the characteristic fault to the FEM, in particular, the fault to the frame of the FEM is analyzed and presented; the fault to cable insulation; the consequences of increasing resistance and heating of the contacts at the junction of the cell busbar FEM; the decrease to the impermeability of the FEM and others.

The general topic of this paper is to study the possibilities of using renewable energy sources to supply urban consumers electricity, consumers located in areas affected by industrial restructuring. This carries out a comprehensive study on the possibilities of using renewable energy sources in the Motru Basin area. Moreover, creation a mix capable of producing the electricity needed by the inhabitants, in household consumption and not only, is being studied. The entry of free energy market has brought about the alignment with competitive conditions and observance of pollution regulations in force, and energy production has determined retrofitting or restriction of the activity of some thermal power plants due to non-competitive costs for primary energy resources. Our country has a diversified and balanced energy mix (hydropower, nuclear energy, coal and natural gas) but it must be complemented by renewable sources (wind, solar, biomass) to provide stability and energy safety prospects.

Primary Energy Supply

As energy is a vital element for sustained economic growth and development, therefore energy consumption is used as a basic indicator of people’s living standards. Due to technological and industrial development, the demand of energy in Pakistan is increasing more than the total primary energy supply; therefore, it is confronting the severe energy deficit today. So there should be a serious concern for the government about the energy security and should take actions for the development of indigenous alternative and renewable energy resources. Renewable portfolio supply (RPS), and carbon tax are the two indirect policy options used for the improvement of energy security. Renewable Energy Promotion is used to reduce greenhouse gas emission, promote local energy sources and improve energy security through reducing energy dependency and diversification of energy sources. Carbon tax is an indirect policy option for energy security enhancement through emission reduction. Imposing tax on carbon emission will alter the primary energy supply mix, more efficient fuel and technologies will be substituted for less efficient fuel and technologies. This will reduce the primary energy demand and lead to improved energy security.
