The article provides a general characteristic and detailed analysis of the main spheres of the fuel and energy complex of Lviv Oblast. The paper proves the importance of development of the fuel and energy complex for the economy of Lviv Oblast and the welfare of its residents, for it fulfills the needs of the entire economic complex in fuel and energy, creates preconditions for development of various types of production, forms the basis for improvement of energy security of the region and country in general. The peculiarities of development of the fuel and energy complex were determined, the main of which are: large amount of coal extracted by mining, small-scale extraction of peat, absence of major electric power stations and high percentage of incoming electric energy from other regions. The paper gives a characterization of the energy balance in the Oblast, and also structure of reserves of coal mines and oil deposits. Areas promising for extraction of bituminous and brown coal, oil, gas, peat and other fuel resources were determined. The structure of consumption of fuel-energy resources by types of organic fuel was determined. Patterns of consumption of the main types of energy carriers in the region were distinguished. The structure of capacities of alternative energy resources in Lviv Oblast was determined. We determined the reasons for the low efficiency of use of natural resources and peculiarities and problems of the development of the energy sphere in the region, the main of which are the unsatisfactory technical condition of the objects of the fuel and energy complex, non-effective system of management in the sphere, absence of new sources of providing primary energy resources. We suggested recommendations on increasing the efficiency of functioning of the fuel and energy complex on the basis of use of non-traditional types of energy sources, i.e.: energy of sun, wind, biomass of solid fuel and others, which would allow natural and financial resources to be saved.

The energy sector of the Republic of Belarus is one of the key sectors of the national economy, the effective development of which ensures the operation of the entire real economy and the sphere of housing and communal services. Due to the lack of the necessary amount of its own energy resources, the country is affected by factors of internal and external threats that form the energy dependence of the Republic on the supply of fuel and energy resources from outside. This weakens its energy security. The main importing country of fuel and energy resources for the Republic of Belarus is the Russian Federation. In this regard, the concept of energy security needs to be clarified, taking into account external and internal threats. The article deals with theoretical approaches to the definition of energy security, the specific features for the importing and exporting countries. The main threats to energy security for the Republic of Belarus are clarified, the causes of their occurrence and consequences for both fuel and energy complex enterprises and energy consumers are revealed. To determine the level of energy security, the indicative assessment method, which involves the identification of parameters and indicators of the development and functioning of the fuel and energy complex, its subsystems and facilities, as well as energy consumers, is the most optimal. These parameters characterize the composition, depth and territorial framework for the implementation of threats to energy security, its level. The indicators of the main directions of energy safety have been analyzed in dynamics; their levels are determined by periods. The directions of energy security, which are most and least susceptible to threats, have been identified. A combined approach for determining the objects of energy security is proposed. The author's definition of energy security is presented.

Insufficient Knowledge

This paper attempts to improve the understanding of the available world energy supply data, which are being imperfectly interpreted and increasingly used. There are basic differences in reserves concepts and definitions between the primary energy resources. There is insufficient knowledge to justify the apparent precision of original measurements of most energy resources. The collection of energy data is in many diverse hands, but of paramount importance is collection close to source, because original estimates are progressively amended by opinions which are difficult to ascertain and assess. The factors affecting energy demand are not yet sufficiently understood to take full advantage of the potential of mathematical models. Cooperation between the energy industries must develop. Experience in preparation for the 1974 Survey of Energy Resources by the World Energy Conference illustrates these points of which an understanding is necessary for wise consideration of world energy problems.

Flow distribution calculation is the determination of the values of the state parameters at the nodes and connections of the system that satisfy the Kirchhoff laws. This calculation is necessary to determine the existence and admissibility of operating states in a multi-energy systems, as well as in singleproduct systems. In addition, it is an essential component of solving the problems of optimization of states in order to ensure the minimum cost of production, transmission and distribution of energy resources. Traditionally, a means of such minimization is the redistribution of the load between sources, consumers and storage of energy resources. As a consequence, this redistribution applies to the elements of transmission and distribution networks. This means are supplemented also by the possibility of converting energy resources from one type to another in multi-energy system. Covering the needs of the end consumer in different types of energy can be provided from different primary energy carriers through the chain (sequence) of their transfer and transformation from one type to another. Such a variety of the ways of energy supply, along with the possibilities of storing (accumulating) energy, pro-vides necessary degrees of freedom for solving states optimization problems.

Renewable Energy Systems

Fluctuations in fossil fuel prices significantly affect the economies of countries, especially oil-importing countries, hence these countries are thoroughly investigating the increase in the utilization of renewable energy resources as it is abundant and locally available in all the countries despite challenges. Renewable energy systems (RES) such as solar and wind systems offer suitable alternatives for fossil fuels and could ensure the energy security of countries in a feasible way. Zimbabwe is one of the African countries that import a significant portion of its energy needs which endanger the energy security of the country. Several studies in the literature discussed the feasibility of different standalone and hybrid RES either with or without energy storage systems to either maximize the technical feasibility or the economic feasibility; however, none of the studies considered maximizing both feasibilities at the same time. Therefore, we present a techno-economic comparison of standalone wind and solar photovoltaic (PV) in addition to hybrid PV/wind systems based on maximizing the RES fraction with levelized cost of electricity (LCOE) being less than or equal to the local grid tariff where Gwanda, Zimbabwe, is the case study. The methodology suggested in this study could increase the utilization of renewable energy resources feasibly and at the same time increase the energy security of the country by decreasing dependency on imported energy. The results indicate that the PV/wind hybrid system does not only have the best economic benefits represented by the net present value (NPV) and the payback period (PBP), but also the best technical performance; where the maximum feasible size of the hybrid system-2 MW wind and 1 MW PV-has RES fraction of 65.07%, LCOE of 0.1 USD/kWh, PBP of 3.94 years, internal rate of return of 14.04% and NPV of 3.06 × 106 USD. Having similar systems for different cities in Zimbabwe will decrease the energy bill significantly and contribute toward the energy security of the country.
