Difficult Issue

Synchronizing heterogeneous processes remains a difficult issue in Scheduling area. Related ILP models are in trouble, because of large gaps induced by rational relaxation. We choose here to deal with it while emulating the interactions which take place between the various players of such heterogeneous processes, and propose a pipe-line decomposition of a dynamic programming process designed in order to schedule energy production and energy consumption.

The Future

This paper built up GM(1,1) models for energy production and consumption in China. Then predicted and analyzed total amount of energy production and consumption in China as well as the structure of energy. The study showed that GM(1,1) model can simulate and predict the trend of the total amount of energy consumption and the structure well. In the future, the structure of energy consumption will be optimized. The proportion of coal and oil will decrease and the proportion of gas and renewable energy sources will increase in order to fill the gap.

Purpose of the paper is to analyze main trends of bioenergy development in the EU, identify successful examples and existing problems and also to suggest some recommendations on implementing the best European practices in Ukraine’s bioenergy sector. State of the art and prospects for the development of bioenergy in the EU-28 until 2030 are presented. It is shown that bioenergy is an important part of European Union’s energy sector and the biggest contributor to renewable energy production. The EU is getting on quite well with achieving its RES 2020 targets set by the Directive 2009/28/EС. By now at least ten counties have already attained their obligatory share of renewable energy in the gross final energy consumption. According to expert estimation, under further pursuing of the favourable policy, the present share of RES in EU’s energy consumption may double and reach about 34% in 2030. Main features of bioenergy part in different EU’s energy production and consumption sectors are analyzed. Traditionally, in the EU, biomass contributes mostly to heat production and its leading part among other RES in the sector is expected to remain beyond 2020. The situation in Ukraine is in line with this trend. The difference is that in the EU most part of heat is produced combined with power, and in Ukraine there are few biomass CHP plants. Besides, power production from biomass is behind other RES in Ukraine in contrast with the EU. Based on the main trends existing in the EU, one can recommend the priority development of biomass CHP to Ukraine and also some higher contribution of biomass to power production compared with other RES. In addition it is suggested that Ukraine should pay more attention to the production and consumption of second generation biofuels and implementation of sustainability criteria in the bioenergy sector.

<p>In the proposed system, a strategy for the control of energy consumption by home appliances is provided. The statistics of previous energy production and consumption of a case study city are used in providing the strategy. In the design of the proposed system, home appliances are categorized into three levels of priority, even though it can be more than three. In this article the control of energy consumption is achieved using a real time energy consumption manager (ECM) based on stored data without the need for real time communication. The system which is proposed here is affordable and simple. Also, it does not require grid upgrade or power line communication through the grid. </p>

The objective of this study is to derive a design methodology for a zero-energy building considering the energy production and consumption of the building. In order to establish the design methodology, various factors affecting the energy production and consumption of the building are derived, and the effect of the heat transmission rate, the surface to volume ratio (S/V ratio), the location and the orientation of the building are analyzed by simulation method. As a result, the S/V ratio and the heat transmission rate are the most important factors in the central region of Korea where consumes large amounts of heating and cooling energy. This is because the final energy consumption varies depending on the heat loss through the envelope. It was confirmed that solar power generation is the most important factor in the southern regions of Korea where the energy consumption is relatively small. The final energy consumption varies depending on the solar power generation in these areas. Therefore, when designing a zero-energy building, the zero-energy of the building can be achieved by using the design methodology established in this study.

The authors of the article analyze the problems of legal regulation of rational subsoil use and energy consumption in Russia, Germany, USA, Japan and other countries. It also compares the energy legislation of different countries. Based on the results, it was concluded that the development of the legislation of these countries is in general compliance with the strategic goals in the field of energy production and consumption. These goals are the construction of ecologically clean "green" energy based on the rational use of mineral resources and minerals and the rational and efficient distribution of energy.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.
