Russian Federation, Shakhty PROSPECTS FOR THE DEVELOPMENT OF ENERGY MANAGEMENT SYSTEMS IN THE RUSSIAN FEDERATION
Abstract. This article deals, an analysis was made of the state of the main problems in the energy sector. Modern methods of controlling generation, transportation and distribution of electric power were studied. The table of comparison of methods of the account of the electric power in Russia with some European countries is resulted. The structural scheme of intellectual metering of electric power is given. Next, intelligent grid networks (Smart Grid) were reviewed - modernized power supply networks using information and communication networks and technologies to collect information on production and consumption of energy.
Keywords: Electric power, control systems, street lighting, intelligent accounting, intelligent networks.
Introduction. Recently, electrical networks around the world have undergone a radical restruction. These changes are connected with the wide introduction of geographically distributed alternative energy sources in the energy system. Based on the traditional approaches to managing distributed objects for geographically distributed energy systems, the principles of centralized, hierarchical and distributed control can be applied. The most effective of them is the use of intelligent control systems.
In Russian Federation and abroad a lot of specialists are working at the development of concepts of intelligent network technologies. Prospects for their development in Russian Federation can be formulated as follows:
- development of renewable energy sources;
- development of distributed energy;
- reduction of power losses due to the construction of intelligent metering systems, taking into account the quality of electricity and limiting the load;
- development of the communication environment, providing information exchange between energy suppliers and consumers;
- use of intelligent equipment and software to ensure the reliability of the
work;
- Use of high-performance energy storage devices to equalize the load
graph.
Intelligent energy networks
Intelligent networks are specific application of intelligent energy systems that, with information technology, correct the flow of electricity between suppliers
and consumers. Intelligent networks contribute to the generation, distribution and consumption of electricity. The electrical system becomes prognostic, communicative and controlled. The goal is to make intelligent networks flexible and able to accurately interact with the behavior and actions of all connected users. Recently, an advanced measurement infrastructure has been widely implemented abroad (AMI). It allows measuring energy consumption in detail at a higher frequency. This results in a large volume of smart meter data that shows more information about consumer behavior and displays them on the site. It allows the information system to introduce various price rates for electricity consumption depending on the time of day and season. An intelligent information system collects and transmits information to system components, such as service providers and customers. For example, consumers can benefit from information provided by the system to rationally use electricity, and lower tariffs. Figure 1 shows a comparison of the current power supply system and the intelligent system. One of the main problems of intelligent accounting is the extraction of useful information from a large amount of data (from households, office buildings). The solution to this problem is Big Data technologies that include powerful sets of algorithms. It facilitates the analysis, interpretation and detection of hidden structures in data of an intellectual dimension.

Using Smart Grid technology is effective in the following tasks:
- intelligent systems for monitoring, integrating and managing renewable energy sources;
- distributed devices for the production and storage of energy based on methods of artificial intelligence;
- intelligent systems focused on monitoring and managing electricity parameters by consumers;
- management of electricity consumption;
- load monitoring under extreme conditions;
- automated transmission, processing and provision of information on energy consumption;
- formation of situational databases on energy consumption;
The conclusion. Based on the analysis, we can conclude that the use of intelligent power supply networks can achieve the following effects:
- reduction of technological and minimization of commercial losses;
- reduction of consumer spending and receipt of additional income;
- new markets, industries, jobs;
- increase in energy efficiency;
- growth in the environmental friendliness of energy;
- cyber-physical security;

Senior teachers Tashkent Institute of Finance Uzbekistan, Tashkent city ACTUAL PROBLEMS OF THE METHODS OF TEACHING FOREIGN
LANGUAGES
Annotation: The article is devoted to the problem of usage of information technologies in teaching foreign languages. The author considers theoretical approaches to teaching by means of new information technologies. The teaching paradigms are presented in detail. The role of the internet in the educational environment is specified. The influence of the internet technology on the process of foreign language teaching is presented.
Keywords: multimedia technologies, information technologies, teaching paradigms, communication in the network.
It should be clarified that to understand the Internet as a complex, multilevel phenomenon, there is only one single right approach, be it constructivism or pragmatism. But any theory is just a horizon line for practice. It is necessary to show how theoretical approaches contribute to intellectual orientation in the network of practical activities. After the signing of the Bologna declaration by Russia, aimed at the formation of a European space for higher education, there is an urgent need for students to learn foreign languages using the Internet and new communication technologies. This prepares the basis for the development and testing of joint European student projects at senior courses. It should be said that students already need both theoretical and practical knowledge in the field of applying new technologies. In addition, their training must meet modern requirements, so that they can independently improve their professional level. Thus, the textbooks of the German publishing house "Bertelsman Stiftung", "Klett" for the last few years contain tasks and links to the Internet, and with them our students need to work on the curriculum. In addition, the student must contact German universities in order to discuss methodological problems and improve the level of knowledge of the German language.
There is a need to determine the impact of new technologies and the Internet on changes that already occur in the system of teaching foreign languages. We are talking about changes in the content of the methodical training of future teachers of foreign languages by incorporating in it the knowledge and skills necessary for using Internet technologies in teaching foreign languages for interactive interaction in information and communication networks. All the knowledge and
