The electric power industry is the largest CO2 emitting sector in the national economy. So optimize the power structure is an important part of energy conservation. This article selected the data of power supplydemand and the power structure in Hebei Province from 2004 to 2011 on the basis of the analysis of the power structure. It established a short-term prediction model based on gray theory, and made the power supply and demand situation and the power structure prediction of Hebei province in the next five years, and provides a reference for the scientific development of the power structure optimization of Hebei Province in the low-carbon context.

The construction of intelligent power supply systems for rural consumers (microgrids) is a promising concept for the development of the energy infrastructure of agricultural facilities. In the process of designing and operating micro-networks, a large number of technical, organizational and legal issues arise, the correct answer to which affects on the reliability, quality and efficiency of electricity supply to agricultural facilities. The analysis of the documentation regulating these processes is of particular relevance. (Research purpose) The research purpose is in analyzing the documentation regulating the construction and operation of intelligent power supply microgrid systems for rural consumers. (Materials and methods) The article reviews regulatory documents in the field of regulation of the electric power industry, distributed generation facilities, renewable energy sources, and the functioning of retail electricity markets. Authors used the method of system analysis, methods of comparisons and analogies, and expert assessments. (Results and discussion) The article presents the issues of functioning of micro-networks of rural consumers as part of the power system, in retail electricity markets; implementation of technological connection and integration of micro- networks into distribution networks. Authors evaluated the regulatory and technical documents regulating the general technical requirements for the design and operation of micro-networks. Domestic and foreign standards for the connection and parallel operation of micro-networks with distribution networks as part of the power system and special documents on micro-networks has been studied. (Conclusions) The article proposes measures for the development of GOST R based on the European IEC TS 62898-1 «Microgrids», harmonized with the requirements of Russian standards, taking into account the features of the Russian electric power industry and agriculture. The article notes the need to make changes to the Russian network codes to ensure the integration of rural micro-networks. The measures of state support aimed at stimulating the spread of intelligent power supply systems for rural consumers were cited.

Today, the electricity supplier is not able to declare the possible level of quality of electricity supply, and the consumer simply does not have the opportunity to buy such "high-quality" electricity. In such conditions, a differentiated approach to tariff formation is inevitable, which has been implemented in practice today, albeit in its infancy. Further improvement of the tariff-forming mechanism is impossible without creating a "flexible" dependence of the tariff on the quality indicators of the consumer's power supply. Quality indicators, in turn, are based, on the one hand, on the methods and approaches for their determination, and on the other, on statistically reliable data on the elements that make up the equipment in the "generation-consumer" chain. In recent years, there has been a tendency to change the concept of development of the electric power industry, since preference is given to the development of sources of distributed generation. Distributed generation is understood as a source of electrical energy directly connected to the distribution electrical network or connected to it by consumers. Ensuring the socio-economic stability of society and a decent quality of life for the population largely depends on the reliability and efficiency of the functioning of the infrastructure for the supply of fuel and energy resources, in particular, electricity. Excessive losses of electricity during its production, transportation and distribution, as well as an unacceptable level of harmful emissions into the atmosphere, are the cause of interruptions in power supply to consumers and even the threat of systemic accidents in the United Energy System (UPS) of the country. The introduction of alternative energy sources in electric power systems, in addition to reducing the harmful impact on the environment and solving the problems associated with waste pollution during electric power generation, will reduce the use of natural resources and relieve the backbone and distribution power lines. As part of the scientific search, an approach was proposed, which is the basis for calculations to determine the optimal installation locations for sources of distributed generation of an average overhead line. The results obtained are presented in the framework of a joint technical meeting of leading specialists of operating enterprises, the customer and the staff of the Department of Power Supply named after V.M. Sinkova NULES of Ukraine.

Low-carbon economy has become a development trend in the international energy sector. Our national electric power industry as a part of the energy sector has to change the power structure in order to follow this climate. In this paper, from the perspective of cost-benefits, based on the analysis of impact of the indicators of the power structure, we establish a index system of the planning low-carbon power structure. Combined with the method of analytic hierarchy process, we re-plan the traditional power structure. Finally quantify the distribution proportion of the thermal power, hydropower, wind power, nuclear power and solar power.

The face of the world economic development has transitioned to a low-carbon economy, in order to meet the dual challenges of climate change and scientific development, the development of low-carbon economy has become the reality of the development of key choice. In this background, based on energy consumption situation in Hebei Province,we use GM (1,1) gray prediction model to predict Hebei Provinces energy consumption and energy consumption structure in 2003-2010. Based on the analysis of the results, support from the policies, laws, and adjust the industrial structure, promote the three levels of the low-carbon concept has made a number of recommendations for the Hebei Province future energy planning and low-carbon development.

As one publicly owned company monopolizes the electricity supply, Korea’s power market has been distorted. Firms faced with constraints imposed by a regulatory environment are likely to fail to minimize their production costs subject to market prices. In this paper, we test for allocative efficiency of fuel inputs for the Korean electric power industry over the period of 1990–2015. The potential cost savings and maximum power supply price markdown are calculated by imposing allocative efficiency. The power plants, on average, could have reduced their fuel costs by as much as 22.1% annually. The attainment of allocative efficiency would have enabled the power supply price to be cut by 7.6% annually.

The global climate change require human production and life must go into the low carbon times of low energy consumption,low emission and low pollution objectively, and now the low carbon development of electric power industry becomes the important link to realize the aim of energy saving and emission reduction. With the necessity analyses of carbon emission reasonable control in electric power production, this paper first proposed the thought of regional electric power overall low carbon,then comprehensive summary origin measures from generation side, transmission side and consuming side. This paper set up the optimization system of regional electric power low carbon, proposed the development degree and combination weight model to empirical study,which provide the effective theoretical basis for low carbon concrete measures.
