Modern energy is at the crossroads of cutting-edge technologies that are revolutionizing the way power systems are controlled, managed and optimized. Leading the way in this process are IoT (Internet of Things), FPGAs (programmable gate arrays), and microcontrollers, including powerful devices such as ESP32. These technologies not only significantly improve the efficiency and reliability of energy systems, but also open up new prospects for creating sustainable and intelligent energy infrastructures. In the Republic of Kazakhstan, energy systems are actively monitored and optimized in order to ensure stable development and meet the growing energy needs of society. The use of IoT technologies allows you to quickly collect data on the operation of energy networks, analyze electricity consumption and predict changes based on information from sensors installed in various network nodes. The use of an FPGA provides high-speed processing of large amounts of data, which is necessary for real-time monitoring and control in conditions of rapidly changing load and dynamic energy processes.

The development and spread of digital and intelligent (IoT) technologies, their radical penetration into all sectors of the economy and society is gaining momentum, changing traditional business models, traditional industry structures and schemes of world markets. The scale of the changes is so great that it is safe to say that this is another technological revolution in which digitalization is almost synonymous with competitiveness. Despite the fact that the idea of the "Internet of Things" appeared about 20 years ago, the active development of technologies began only in recent years. The relevance of this direction is constantly growing. A smart environment is impossible without the interaction of its objects, and it is the concept of the Internet of Things (IoT) that takes this interaction to a new level. The Internet of Things allows you to quickly obtain factual information, quickly analyze it, and, accordingly, make informed decisions and measures. The paper explains the terms "IoT technologies in the energy sector", which define the unique content of the processes behind them. A conceptual vision of the development of the electric power industry based on the principles of IoT technologies and a development scenario are presented. The Internet of Things (IoT) is beginning to define the future of many industries and emerging markets. One of the IoT target markets is energy systems. IoT is the production, transmission and processing of information, so everything that is part of the system, including software and hardware, should be considered as a whole. This article presents the current state of IoT-based energy systems to review the latest activities for each IoT component in energy systems. Problems in this subject area are discussed, and then some solutions are presented.

The city of Turkestan, Kazakhstan is experiencing growth leading to an increased need for electricity. In order to meet this demand the city is upgrading its infrastructure specifically focusing on improving its 35/10 kV substations. Engineers are utilizing calculation software like RastrWin3 to design and analyze these substations. This software offers capabilities, for modeling substations. Using RastrWin3 the ability to import data from sources like drawings AutoCad, GIS maps and other relevant resources. This imported data serves as the foundation for constructing the substation model. Engineers can easily incorporate components such as transformers, feeders, circuit breakers and busbars into the model. Each element of the model can be assigned parameters like voltage, current, resistance and power to represent real world conditions. Additionally, load profiles can be generated for analysis purposes to capture fluctuations, in energy demands throughout the day and year. Numerical calculation software plays a role, in the design and analysis of substations. It provides engineers with a toolset to achieve the following objectives: 1. Construct models of substations. 2. Simulate the behavior of substations under operational conditions. 3. Resolve issues that may arise in electrical substations. 4. Enhance the design and optimization of substations. One notable software in this domain is RastrWin3 which offers capabilities for calculations and simulations related to electric substations. Engineers can utilize this program to evaluate power systems, in emergency and transient modes. Accounting for various factors such as non-linearity, power and reactive power losses, as well, as the influence of capacitive coupling. Various types of loads such, as consumer loads, substation auxiliary loads and loads from protection and automation devices are considered in the modeling process. The software RastrWin3 is utilized to design and analyze 35/10 kV substations, in Turkestan. This software assists in enhancing the precision of substation design reducing the time needed for designing and developing substations improving substation efficiency and lowering maintenance costs.

The theme “Energy of the Future,” presented by Kazakhstan at EXPO-2107, is one of the most relevant and globally significant for modernity, concerning the whole world—the sustainable use of energy. The issues of developing renewable non-traditional energy sources have largely been considered in scientific and technical programs of different countries. Particularly, such countries as the USA, Japan, Israel, and Germany work on these energy sources at the level of long-term national programs. As for the possibility of using solar energy in Kazakhstan, it is a country in Central Asia with great potential for solar energy. Solar energy resources in the country remain stable and suitable due to favorable climatic conditions.

В статье исследован фракционный состав железной руды и дана оценка ее гравитационной обогатимости на начальной стадии технологиче- ских исследований. Анализ распределения железа по классам крупности и плотностным фракциям позволил предварительно определить степень раскрытия минералов и перспективность гравитационных методов. Рентгенофазовый анализ установил, что основной ценный компонент представлен слабомагнитным гематитом. Ситовый анализ показал равномерное распределение железа по крупности, при этом до 94% железа сосредоточено в классе -50+2,5 мм. Обработка кривых гравитационной обогатимости выявила легкое выделение тяжелых фракций с содержанием Fe свыше 55% при плотности разделения 3400–3500 кг/м³. Рекомендуется применение отсадки для промышленного обогащения. Работа имеет практическое значение при проектировании схем переработки железных руд Казахстана.

We develop a complex technology of separate processing of fine dust including the procedure of preliminary firing of dust with removal of arsenic from the technological scheme with subsequent application of a hydrometallurgical scheme for the extraction of copper and rhenium: sulfuric-acid leaching of cinder with cementation separation of copper with iron, and extraction of rhenium from the solution. Complex analytical studies of the intermediate and final products were carried out by the methods of atomic-emission spectrometry with inductively coupled plasma and X-ray phase analysis. The compositions of liquid solutions were determined by the method of chemical analysis. The rhenium contents in the original solutions and extraction products were determined by the methods of colorimetric and chemical analyses. This guaranteed the possibility of step-by-step quality control of the obtained products in the course of realization of the technological cycle of processing. As a result of laboratory investigations, we established the following optimal parameters of copper cementation: a temperature of 333°K (60 °C), S:L = 1.5, and a duration of the process equal to 60 min for which we obtained powdered cement copper with the following composition (wt.%): 82.0 Cu, 09.27 Pb, 1.49 Zn, 0.19 As, 0.72 Fe, 0.03 Re, 3.43 O2; balance 11.89. The extraction of copper into a commercial product was as large as ~98%. We obtain new data on the extraction of rhenium from sulfuric-acid solutions of the process of cementation by using an extractant containing (wt. %): 10 trialkylamine (TAA), 80 kerosene, and 10 di-2-ethylhexanol. On the basis of the indicated components, it is possible to choose the composition of the extractant for the processes of extraction of dusts of different types and compositions. We obtained commercial ammonium perrhenate with a rhenium content of 69.17% corresponding to the AR‑0 grade. The end-to-end extraction of rhenium into ammonium perrhenate is as high as 93%.
