Abstract:

Purpose – This paper aims to demonstrate the complex inter-relationship of non-technical barriers involved in the implementation of decentralised energy (DE) projects. To meet its ambitious 2050 target of 80 per cent carbon emission reduction, the UK needs to increase dramatically the wider uptake of DE systems. Many examples exist internationally of DE systems leading to enhanced carbon emissions reductions, including systems based not only on technological but also on more innovative policy, financial and social-economic approaches.

This system records and simulates how much electricity is generated from renewable sources (biogas, solar, wind, etc.) on the farm. This is compared with the consumption of the barn technology (milking robot, feeding robot, etc.). This energy management is regulated according to the needs of the c

Abstract:

This paper describes the technical-economic analysis of a hybrid renewable energy systems (HRES) connected to the grid, consisting of photovoltaic (PV) source and municipal solid waste (MSW), taking into account economic and technical criteria. Photovoltaic energy and the new technology used for MSW processing have a lower cost and lower environmental impact. The sensitivity analysis shows that improving the rate of return on investment in HRES can be a measure to encourage the use of renewable energies for electricity production, both in terms of costs and environmental impact.

The article stipulates that at present, the grinding technology strives to increase the degree of grinding, improve the granulometric composition of cement and reduce the specific energy consumption for grinding processes, taking into account the extremely low efficiency of grinding plants. Therefore, when choosing the optimal dosages, the fineness of the grind of cements at various grindings was studied.

The studies were carried out in order to propose a criterion for the technical and economic assessment of photovoltaic systems layout options, which allows providing consumers with electric energy at a cost lower than the current tariff in the Unified Electric System, and meeting the requirements for the payback of projects in the energy sector. The theoretical basis for the search for an economically viable option for the layout of the modules of the photovoltaic system was the mathematical formulation of the optimization problem using the following criterion: the cost of generated electrical

Introduction. The complication of the spacecraft payload requires the use of non-standard circuits. The analysis of scientific and technical publications shows that there is no formalized methodology for spacecraft energy-converting equipment designing. Reviewed publications consider some design algorithms taking into account one (efficiency) or two criteria (efficiency, weight and size characteristics). At the same time, the issues of ensuring trouble-free operation of energy-converting equipment are not sufficiently considered which leads to rejection of most part of proposed circuitsolution

This paper presents a probabilistic model for supporting the process of decision making about the value of new lighting systems in existing road tunnels when some data and parameters are affected by uncertainty. The proposed model, which we have called Probabilistic Energy Screening of Tunnel (PrEST), accounts for both the technical performance and the economic objectives of the new lighting systems. The technical performance is described on an adequate (x, y) plane that was defined by two indices. The first index measured the consumption of electricity per kilometre of tunnel lengths; the sec

The article proposes to evaluate the efficiency of an autonomous vehicle, taking into account not only the energy consumption for motion, but also the time of motion, i. e. both factors — efficiency and performance — should be taken into account. As a criterion for evaluating the efficiency of vehicles, authors propose the multiplication of efficiency on performance — the energy efficiency indicator (EEI). The best will be the vehicle with the highest EEI. The indicator should be calculated according to the specified technical characteristics of the vehicle laid down in the technical specifica

An energy-informational memristor model describing this nonlinear physical and technical effect and a parametric block diagram for describing such nonlinearity are proposed.
