Abstract:

Fusion power concepts that are heated by electrical devices for the purpose of producing high levels of electrical output are in effect electric power amplifiers. Three systems are considered: A hypothetical electric power version of the ITER experiment, the ARIES-1 fusion reactor design, and a modified version of ARIES-1 with stainless steel structural material. We find that an ITER power plant with a reasonable electric power conversion system would produce no net electric power at its target energy amplification factor of 10. The ARIES-1 conceptual power plant, as conceived, would have an energy amplification of 22 and an electric amplification of 6. If stainless steel were substituted for the SiC composite material assumed, the ARIES-1 electric power amplification would drop to roughly 3. We conclude that practical fusion power plants will likely require a near-ignition operating mode and qualified high temperature materials as prerequisites for commercial viability.

Abstract:

Under the background of increasingly serious environmental pollution, virtual power plants have become an effective way to solve environmental pollution due to the characteristics of integrating a large number of clean distributed energy generation. At the same time, electric vehicles with dual attributes of power supply and load bring opportunities for the further development of virtual power plants. In this paper, the ideal matter-element comprehensive benefit evaluation model of virtual power plants is constructed by constructing the index system and weighting model of virtual power plants considering electric vehicles. The virtual power plants connected with different proportion of electric vehicles are taken as an example analysis. The results of the example analysis show that the comprehensive benefit of virtual power plants is the highest when the proportion of electric vehicles access reaches 120%.

Abstract:

The article provides an analytical review of reverse-acting electric energy storage devices that can be used to solve systemic problems of the United Energy System of Ukraine. The need for the use of electric energy storage is due to the existing shortage of maneuverable capacities of the United Energy System and the construction of solar and wind power plants, which, due to the stochastic mode of operation, are a significant destabilizing factor. Due to the lack of market pricing mechanisms, the possibility of adjusting the rates of the "green" tariff, and the decrease in the cost of solar and wind power plant technologies, a rapid increase in their number and capacity has been observed in recent years. At the beginning of 2021, the installed capacity of solar power plants was 6.87 GW, and wind power plants – was 1.31 GW, and by 2030, their growth is planned to be 10.5 GW and 5.0 GW, respectively. Without adequate regulatory capacity, this can lead to catastrophic consequences, as happened in South Australia. The conducted review and analysis showed that the dominant technology of electric energy storage in the world is hydro-storage power plants, the implementation costs of which are about 260 USD/kWh. Compressed air energy storage is the cheapest technology but needs to be located near the energy systems of natural caves. Accumulator systems of energy storage are developing at a fast pace, the costs of their implementation are 311-520 USD/kWh with a tendency to decrease by 2030 by about 25%. They are the most promising for work in energy systems. These storage devices can be used to regulate frequency and power, reduce electricity flows, reduce voltage fluctuations in electrical networks, consolidate daily schedules of electrical loads, prevent overloads of electrical networks and transformers, increase the reliability of electricity supply, increase the stability of the operation of solar and wind power plants, as well as for commercial purposes in various segments of the electricity market of Ukraine. Keywords: energy system, electricity storage, power, capacity.

Abstract:

Improving the operational efficiency (OE) of thermal power plants is one of the most important problems of electric power systems (EPS). According to modern concepts, efficiency is the simultaneous consideration of three properties of objects, viz. economy, reliability and safety. The methodology of their joint assessment assumes that the service life of the main equipment does not exceed the standard value, but this condition is now met by less than half of the production enterprises of a lot of EPS. In order to increase OE, it is necessary, first of all, to learn how to objectively compare the performance of objects both of the same type – in a given time interval, and unique ones – in adjacent intervals. Existing methods for calculating integrated performance indicators do not fully take into account the random nature of technical and economic indicators (TEI). The article presents a new method for comparing the OE of EPS objects, the essence of which is to switch from joint consideration of TEI to analysis of their relative changes in comparison with the factory default value (nominal value). Relative values of indicators characterize the amount of wear or residual life. In this case, for example, the arithmetic mean of the relative values of the TEI determines the average wear of the object. This physical representation enlivens integral indicators, and their comparison and ranking ceases to be science-intensive. It is proposed to take into account also the degree of variation of relative deviations (wear), which is adequate to the object’s misalignment. It manifests itself in a significant change (deterioration) of one or (less often) two relative values of the TEI in the calculated time interval (month) and is characterized by such statistical indicators as the geometric mean and the coefficient of variation of relative deviations. Herewith, if the arithmetic mean value of the object’s wear is restored during major repairs, then the misalignment is eliminated much faster – during current repairs. A necessary condition for the feasibility of using these or those integral indicators is their functional and statistical independence. The results of the studies performed using the simulation method made it possible to establish that the smallest correlation occurs between the integral indicator calculated as the arithmetic mean of random variables and the integral indicator calculated as the coefficient of variation of the same random variables. Comparison of correlation fields clearly confirms these conclusions.

Abstract:

To supply small cities with electric and thermal energy it is proposed to create selfcontained energy complex based on gas turbine plants (GTP), wind generators and electric storage cell. A scheme for the joint operation of these plants is offered, a methodology for calculating the quantitative characteristics of a wind power plant, gas turbines and electric storage cell is developed. Electric storage cell provide coverage the peak portion of the daily electrical load curve. The heat load is ensured by the operation of the waste-heat boiler and the peak boiler. Using the example of a power complex with an electric load of 5 MW and a heat load of 17.5 MW, the generation of electric energy by wind driven power plant and gas turbine plants, the supply of electric energy from electric storage cell, the heat loads of the waste-heat boiler and peak boiler by months of the year are calculated. When the power share of the wind power plant is 0.2, the electric storage cell provide for an annual period from 5.2 to 10.7 % of the daily demand of the electric load schedule. The electric power of the gas turbine plant in winter is reduced to 70 % of the maximum load of the consumer, in summer - up to 55 %. An increase in the relative share of the power of a WDPP reduces the electric capacity of a gas turbine plants, its cost, while the cost of electric storage cell increases.

Abstract:

This article explains research and development in the field of gas turbine power plants. Natural gas fueled gas turbines driving generators are proving to be the most versatile and effective energy converter in the engineer's arsenal of prime movers. Continued research and development are making these gas turbine power plants even more effective, flexible, and efficient. Gas turbine plants can operate under either base load operations or in quick start/fast shutdown modes. The reliable and dispatchable backup capacity of fast-reacting fossil technology to hedge against variability of electrical supply was a key to successful renewable use in the 26 countries studied. The article concludes that the use of versatile electric power gas turbines fueled by natural gas will continue to grow in the world. In the United States, with recent shale discoveries and fracking of natural gas, such use should increase, with or without the emphasis on renewables.

Abstract:

Increasing economic importance of the Arctic, further intensification of northern sea routes, and exceptional sensitivity of the arctic natural environment to anthropogenic impacts are fundamental factors for a comprehensive study of environmental aspects in the application of innovative technologies for the development of infrastructure in the Arctic. Despite the growing interest in low-power nuclear power plants as a distributed generation facility, their possible application in technologically isolated power systems does not lose relevance. The development of both the Arctic and Far Eastern regions of the Russian Federation presents great opportunities and demand for the use of nuclear power sources. Also, development programs for the Russian arctic zone imply a significant increase in the role and number of nuclear power facilities, in other words of potential radiation-hazardous facilities. Large-scale use of nuclear-powered installations in the Arctic necessitates advanced development of a scientifically grounded and modern forecasting system as well as assessments of threats and risks in case of possible radiation emergencies at nuclear- and radiation-hazardous facilities. Also, the development of proposals for necessary measures to minimize negative consequences of such emergencies is required. This is especially true for the case of compact placement of industrial, infrastructure and residential facilities in the Arctic in the immediate vicinity of nuclear facilities. The paper demonstrates that the demand for low-power nuclear power plants and their competitiveness will grow steadily in the conditions of electric-power industry decentralization, further spread of distributed generation and the development of technologically isolated power systems. Approaches to the generation of a low nuclear-power system based on the philosophy of industrialization of production and centralized management are presented. Special features of the environmental impact assessment of low-power nuclear power plants for the development of a methodology to study the radio-ecological hazard related problems are provided.

Abstract:

In order to supply electric power to the safety related loads, safety and reliability of onsite power have to be ensured for the safety function performance in nuclear power plants. Even though the existing electric power system of APR1400 meets the requirements of codes regarding Class 1E system, there is a room for improvement in the design margin against the voltage drop and short circuit current. This paper discusses the amount that the voltage drop and short circuit current occur in the existing electric power system of APR1400. Additionally, this paper studies with regard to the improved model that has the extra margin against the high voltage drop and short circuit current by separation of unit auxiliary transformer (UAT) and standby auxiliary transformer (SAT) for the Class 1E loads. The improved model of the electric power system by separation of UAT and SAT has been suggested through this paper. Additionally, effects of reliability and cost caused by the electric power system modification are considered.

Abstract:

Electric vehicles (EVs) are currently popular, and their number is growing; therefore, they have an impact on the power system. In this paper, the impact of electric vehicles on a power line connected to photovoltaic (PV) power plants regarding the power losses and voltage level is presented. The study is performed for a power line located in Mureș County, Romania, to which two photovoltaic power plants are connected. Three supply options are available for the power line, which supplies 15 loads. The power demand of the loads is determined with the power meters installed at the load premises. Electric vehicles are also considered to be connected in different points along the power line at the buses with the lowest voltage level. The results give the power losses and voltage levels for the case of when the PV power plants and EVs are connected to the power line, compared with the case when the EVs are not connected to the power line. The power losses were 400% higher in the case where the EVs were connected when the power demand was higher, while the voltage level was 2% lower if the EVs were connected.

Abstract:

The modern power system is characterized by the massive integration of renewables, especially wind power. The intermittent nature of wind poses serious concerns for the system operator owing to the inaccuracies in wind power forecasting. Forecasting errors require more balancing power for maintaining frequency within the nominal range. These services are now offered through conventional power plants that not only increase the operational cost but also adversely affect the environment. The modern power system emphasizes the massive penetration of wind power that will replace conventional power plants and thereby impact the provision of system services from conventional power plants. Therefore, there is an emergent need to find new control and balancing solutions, such as regulation reserves from wind power plants and electric vehicles, without trading off their natural behaviors. This work proposes real-time optimized dispatch strategies for automatic generation control (AGC) to utilize wind power and the storage capacity of electric vehicles for the active power balancing services of the grid. The proposed dispatch strategies enable the AGC to appropriately allocate the regulating reserves from wind power plants and electric vehicles, considering their operational constraints. Simulations are performed in DIgSILENT software by developing a power system AGC model integrating the generating units and an EVA model. The inputs for generating units are considered by selecting a particular day of the year 2020, when wind power plants are generating high power. Different coordinated dispatch strategies are proposed for the AGC model to incorporate the reserve power from wind power plants and EVs. The performance of the proposed dispatch strategies is accessed and discussed by obtaining responses of the generating units and EVs during the AGC operation to counter the initial power imbalances in the network. The results reveal that integration of wind power and electric vehicles alongside thermal power plants can effectively reduce real-time power imbalances acquainted in power systems due to massive penetration of wind power that subsequently improves the power system security. Moreover, the proposed dispatch strategy reduces the operational cost of the system by allowing the conventional power plant to operate at their lower limits and therefore utilizes minimum reserves for the active power balancing services.

Abstract:

The analysis of the promising direction of development of energy installations of land transport is conducted. To date, in view of the emerging problems of depletion of oil resources and environmental safety in transport, in some popular science publications and in the media, the idea of the upcoming transition of motor vehicles to electric traction is actively awakening. However, in the opinion of the overwhelming majority of authoritative specialists in the automotive industry, this idea is premature and does not have a serious scientific substantiation. Currently, there is a large investigated potential of replacing oil with alternative energy products, the resource base of which, in some cases, significantly exceeds the traditional raw material base of oil fuels. Wide opportunities to solve the problem associated with the predicted depletion of oil resources are enclosed in the use of natural gases (primarily methane) and vegetable (biological) raw materials for the production of motor fuel. The development of alternative energy is universally considered one of the promising ways to solve the problems of energy supply, both in the field of constantly growing energy consumption in general, and in the direction of the future development of the energy balance of the transport complex. Thus, it is possible to assert with confidence that the domestic automobile transport is guaranteed to be provided with motor fuel for many decades. In addition, the current opinion about the high energy and environmental efficiency of electric motor transport is, in its essence, not unambiguous and for a number of indicators the electric vehicle is significantly inferior to a vehicle with a traditional internal combustion engine. In this article, on the basis of a reasoned analysis involving the opinions of a large number of authoritative specialists in the global automotive industry, this statement is proved.

Abstract:

Safety is an essential topic for electric power plants. In recent years, accidents caused by unsafe behaviors of electric power plant employees are frequent. To promote the sustainable development and safety of electric power plants, studies on the assessment of unsafe behavior are becoming increasingly important and urgent. In this study, accident statistical analysis, literature review, and expert survey are adopted to select more comprehensive and accurate assessment indicators of unsafe behavior of the workers in electric power plants. Data about indicator and unsafe behavior were obtained through a questionnaire survey, and 27 indicators were used as inputs, and the unsafe behavior was taken as the output of a backpropagation (BP) neural network based unsafe behavior assessment model. An assessment indicator system about power plant workers’ unsafe behavior composed of 4 first-level indicators and 27 second-level indicators was established and the weights of the assessment indicators were determined. A three-layer feedforward BP neural network assessment model of “27-13-1” layers was found to be a suitable model. The proposed model can demonstrate the nonlinear complex relationship between the assessment indicator and the unsafe behavior of power plant workers. The model can be helpful to evaluate, predict, and monitor the safety performance of electric power plants.

Abstract:

LNG power generation is emerging as a new alternative. LNG power generation is said to have many environmental and economic advantages, with only 10% emission (emissions : urine output) and excellent efficiency such as facility management compared to thermal power generation such as coal. Accordingly, the government has also changed its policy stance in the direction of converting thermoelectric power plants into LNG power plants and has been providing various benefits to LNG power generation. For this reason, not only private enterprise operators but also public power generation companies are planning to change their facilities to LNG power plants or build new ones. Particularly noteworthy is that major companies, which have been consumers of electricity, are pushing for plans to build LNG power plants by themselves to produce and consume LNG power plants independently. Of course, since LNG power generation is environmentally and economically superior to existing thermal power generation, there is no need to oppose the expansion of LNG power plants. However, the reality is that they are not welcomed by the residents where the power plants are located. Nevertheless, many LNG power plants are already under construction across the country, and almost all of them are facing conflicts with residents. Therefore, in order for LNG power plants to become environmentally, socially, and economically useful and sustainable power generation facilities, legal and institutional measures should be prepared to correct the legislative deficiencies of the current ‘Act on Assistance to Electric Power Plants - Neighboring Areas’ to dispel residents' concerns and opposition. Therefore, legislative adjustments should be made, such as significantly improving the current ‘Act on Assistance to Electric Power Plants’. First of all, it should specify that LNG power plants are included in the current legislation, stipulate not only commercial power plants(utility generation power plants), but also isolated power plants(non-utility generation power plants), and clearly support corporate funding and obligations for their own isolated power plants. Second, it is to improve the unreasonable regulations of the existing Act on Assistance to Electric Power Plants. For example, the scope of the surrounding area should be set around the living area based on the distance from the existing power generation facilities, and sufficient compensation and support should be provided according to the degree of damage to residents. Third, the most important thing is to form an independent and a permanent scheme that jointly investigates and monitors environmental damage, which can be said to be the core of the conflict. This should be the cornerstone of a governance organization, including a producer utility generation(including private power plants), government, resident, representatives, and environmental experts. We hope to become a sustainable power plant that is welcomed by residents through the revision of the Act on Assistance to Electric Power Plants - Neighboring Areas.

Abstract:

The perspective energy sources alternative to hydrocarbons, which are currently used in the world, are considered. Energy-saving technologies for the use of hydrocarbon fuel in vehicles are analyzed. The need to develop the use of electric drives on automobiles is noted. The importance of systematical accumulation and analyzing of the existing experience of operating vehicles with electric drives abroad and in the Russian Federation is considered. Monitoring the technologies developed abroad and the problems arising during the operation of electric vehicles will make it possible to determine the priority ways of their development and to concentrate the efforts of researchers in the direction ensuring the maximum efficiency of their application. One of the currently attractive and economically viable ways of developing road transport for domestic practice is the use of vehicles with hybrid power plants. It is shown that the production of hybrid vehicles and electric vehicles abroad is successfully developing and is nowadays one of the most dynamic in the world. Indicators of efficiency of electric power consumption of vehicles with electric drive of various automobile manufacturers are given. A comparative analysis of technologies for the use of electric automobiles to improve the environmental situation in megalopolises is carried out and the problems of increasing the efficiency of automobile power plants are considered. It is shown that the climatic conditions of the Russian Federation with long periods of low temperatures of atmospheric air strongly affect the energy losses associated with heating the passenger compartment, and to a large extent - on the energy efficiency of the power plant of electric vehicles. To assess the efficiency of using electric vehicles, it is proposed to use a universal indicator of the efficiency of energy consumption. It is proposed to carry out a comparative assessment of the energy consumption of various vehicles by the energy parameter qEL. The calculated data show that the use of vehicles with electric drive and, in particular, rechargeable hybrids is more profitable in comparison with the use of vehicles equipped exclusively with internal combustion engines.
