Almost 75 percentage of the population lives in rural areas and only about 30 percentage of the rural households have access to grid electricity and about 42 percentage of the population no access to the electricity. It is highly difficult to extend high tension transmission lines to these areas as some of the places are separated from the mainland and from each other by wide rivers, creeks and hills. Renewable energy is considered to be the right choice for providing clean energy to these remotesettlements. Off-Grid energy systems are growing in popularity as an independent source of energy to satisfy electricity needs of individual households, small communities and commercial applications. Mainly in Bangladesh where the main grid is either not developed or the grid is noncommercial to extend due to remoteness of the location. A successfully installed Off-Grid energy system for several years to provide a reliable 24-h electricity supply to the inhabitant of an island. The objective of this paper is to analyze and design an off-grid energy system for Bangladesh consisting of PV panels, charge controller, battery and inverter to serve a remote locality. A mini solar grid of 21KWh capacity has been designed.

The theme of the final qualification work: “Parametric Energy-Efficient Optimization of the Project for the Reconstruction of a Cultural Heritage Objectâ€. The work is devoted to the consideration of the issue of reconstruction of historical buildings in terms of energy conservation and energy efficiency.The purpose of the study is to develop a methodology for energy-efficient simulation optimization of the project of a cultural heritage object.The object of study in this work is the cultural heritage object “City Manor, XVIII-XIX centuries – Main House, XVIII-XIX centuries (at the heart of the chamber of the turn of the XVII-XVIII centuries) at the address: building 1, 8 Ul. Prechistenka, Central Administrative District, Moscow†at the stage of its reconstruction.The subject of the study is the energy-efficient simulation optimization of the cultural heritage object reconstruction project.Research objectives:1. Study of the current state of construction of cultural heritage objects and issues of energy efficient optimization.2. Analysis of the actual state of the object and modelling of the energy efficiency class of the building.3. Development of information and analytical building models for energy efficiency analysis.In the course of the study, methods were used to generalize and analyse domestic and foreign experience, compare and evaluate the results of energy modelling for various scenarios.The practical significance of the work lies in the possibility of assessing the energy efficiency of historical buildings using an optimized simulation energy-efficient model.The following results were obtained during the study:-         The information model of the building was built in Autodesk Revit 2022 according to the available design documentation;-         The analytical and energy model of the building was modelled based on the information model created in Autodesk Revit 2022;-         Software calculation of surface insolation and lighting calculation was performed;-         Nine building energy consumption scenarios were modelled depending on different parameters. The best scenario and parameters that need to be changed/optimized to achieve the best result in terms of energy consumption are determined. Energy efficiency benchmarks have been defined for each scenario;-         An analysis of the results of energy modelling was carried out and reports of annual energy consumption were generated;-         Recommendations and proposals were developed for the implementation of energy modelling in the construction process, including process diagrams in BPMN notation. A variant of the hybrid method of sharing BEM and ML (Machine Learning) is also considered. It is applicable for solving problems not only related to energy modelling, but also for solving other problems in construction and reconstruction.This approach makes it possible to increase the investment attractiveness of such projects by reducing energy costs and related costs during the operation period. To achieve such results with a minimum investment of time allows the use of modern methods of parametric design, such as BEM and BIM. The use of such design methods also makes it possible to bring a historic building in line with modern requirements for the reliability, safety and efficiency of buildings, and allows the use of modern materials.

Theme of final qualification work: "Single-phase heating storages in engineering networks." This work is devoted to the study of single-phase heat storage devices and the possibility of their application in the heating system of a residential multi-storey building. The aim of the study was to increase the energy efficiency of heat supply systems by installing a single-phase heat storage. Tasks that were solved during the study: 1. Review of existing heating systems. 2. Construction of a calculation model of a single-phase heat storage. 3. Assessment of energy efficiency. 4. Comparison of various heat storage materials. As a result, a calculation model of a single-phase heat storage device and a list of initial data for it were presented, and was given an example of calculating such a storage device for a certain multi-apartment building and a comparison of two heat-accumulating materials. Based on the results, a choice was made in favor of concrete, as a body-accumulating material. It is worth noting that before that the issue of using single-phase heat storage devices in the heating system for the whole building was not considered. Economic efficiency with the use of such drives is achieved by charging at a cheaper rate (at night), and the consumption of stored energy in the remaining time of the day.

Lemeshko; Sherzod K. Khaldarov;Relevance. The power provided by generating stations based on wind and solar energy depends on the state of the environment at a particular geographical point, the prevailing wind speeds and the level of solar insolation. The wind speeds and solar insolation characterizing patterns are probabilistic in nature and depend on the terrain and season. This means that the power provided by generating stations based on renewable energy sources is also probabilistic. Risks associated with an inaccurate knowledge of the probabilistic patterns describing renewable energy sources, as well as the unpredictability (uncertainty) of the natural environment affecting renewable energy sources, are the reasons why system operators do not take into account such stations in calculating the power balance. This situation does not allow considering the generating stations as full-fledged market participants, covering the flow of investments in such projects. Accurate determination of the output power distribution laws for solar and wind power stations, based on the wind speed and solar insolation data analysis can significantly help system operators in power predicting of the power stations. Aim of study is building models of distribution laws that best describe the results of wind speed and solar insolation observations, as well as models of distribution laws for the generated power of wind and solar stations. Methods: methods for estimating the parameters of distribution laws, methods for testing statistical hypotheses. Results. It is shown, that the 3rd kind of beta distribution laws and their mixtures describe the series of measured wind speed and solar insolation better in the territory. The same concerning the probability distribution of the wind and solar stations power. Distribution law models for wind speed, solar insolation and power of the corresponding stations are constructed. It is shown that on the basis of the law of the distribution of wind speed and the mathematical relationships that connect power with wind speed, good models can be constructed for the probability distributions of power of wind power stations. The models can be used as an auxiliary tool for power system operators to predict output power.

In nominal and close to them modes, power transformers have a fairly high coefficient of performance (COP). However, the efficiency of autotransformers depends on many factors due to their design features. In this study, the authors propose a method for improving the energy efficiency of autotransformers while optimizing the functioning of their cooling system in order to reduce operating losses for electric drives of pumps and fans of forced cooling systems using an autotransformer with a rated power of 125 MVA as an example. Вопросы внедрения эффективных мероприятий по снижению потерь при эксплуатации силового электрооборудования представляют практический интерес для электросетевых и промышленных предприятий. В номинальных и близких к ним режимах силовые трансформаторы обладают высоким коэффициентом полезного действия (КПД). Однако из-за конструктивных особенностей автотрансформаторов их КПД зависит от многих факторов. На примере автотрансформатора АТДЦТН-125000/220/110-У1 номинальной мощностью 125 МВ·А предложен способ повышения энергоэффективности при оптимизации функционирования их системы охлаждения с целью снижения эксплуатационных потерь на электроприводы насосов и вентиляторов систем принудительного охлаждения.

Almost 75 percentage of the population lives in rural areas and only about 30 percentage of the rural households have access to grid electricity and about 42 percentage of the population no access to the electricity. It is highly difficult to extend high tension transmission lines to these areas as some of the places are separated from the mainland and from each other by wide rivers, creeks and hills. Renewable energy is considered to be the right choice for providing clean energy to these remotesettlements. Off-Grid energy systems are growing in popularity as an independent source of energy to satisfy electricity needs of individual households, small communities and commercial applications. Mainly in Bangladesh where the main grid is either not developed or the grid is noncommercial to extend due to remoteness of the location. A successfully installed Off-Grid energy system for several years to provide a reliable 24-h electricity supply to the inhabitant of an island. The objective of this paper is to analyze and design an off-grid energy system for Bangladesh consisting of PV panels, charge controller, battery and inverter to serve a remote locality. A mini solar grid of 21KWh capacity has been designed.

The theme of the final qualification work: “Parametric Energy-Efficient Optimization of the Project for the Reconstruction of a Cultural Heritage Objectâ€. The work is devoted to the consideration of the issue of reconstruction of historical buildings in terms of energy conservation and energy efficiency.The purpose of the study is to develop a methodology for energy-efficient simulation optimization of the project of a cultural heritage object.The object of study in this work is the cultural heritage object “City Manor, XVIII-XIX centuries – Main House, XVIII-XIX centuries (at the heart of the chamber of the turn of the XVII-XVIII centuries) at the address: building 1, 8 Ul. Prechistenka, Central Administrative District, Moscow†at the stage of its reconstruction.The subject of the study is the energy-efficient simulation optimization of the cultural heritage object reconstruction project.Research objectives:1. Study of the current state of construction of cultural heritage objects and issues of energy efficient optimization.2. Analysis of the actual state of the object and modelling of the energy efficiency class of the building.3. Development of information and analytical building models for energy efficiency analysis.In the course of the study, methods were used to generalize and analyse domestic and foreign experience, compare and evaluate the results of energy modelling for various scenarios.The practical significance of the work lies in the possibility of assessing the energy efficiency of historical buildings using an optimized simulation energy-efficient model.The following results were obtained during the study:-         The information model of the building was built in Autodesk Revit 2022 according to the available design documentation;-         The analytical and energy model of the building was modelled based on the information model created in Autodesk Revit 2022;-         Software calculation of surface insolation and lighting calculation was performed;-         Nine building energy consumption scenarios were modelled depending on different parameters. The best scenario and parameters that need to be changed/optimized to achieve the best result in terms of energy consumption are determined. Energy efficiency benchmarks have been defined for each scenario;-         An analysis of the results of energy modelling was carried out and reports of annual energy consumption were generated;-         Recommendations and proposals were developed for the implementation of energy modelling in the construction process, including process diagrams in BPMN notation. A variant of the hybrid method of sharing BEM and ML (Machine Learning) is also considered. It is applicable for solving problems not only related to energy modelling, but also for solving other problems in construction and reconstruction.This approach makes it possible to increase the investment attractiveness of such projects by reducing energy costs and related costs during the operation period. To achieve such results with a minimum investment of time allows the use of modern methods of parametric design, such as BEM and BIM. The use of such design methods also makes it possible to bring a historic building in line with modern requirements for the reliability, safety and efficiency of buildings, and allows the use of modern materials.

Theme of final qualification work: "Single-phase heating storages in engineering networks." This work is devoted to the study of single-phase heat storage devices and the possibility of their application in the heating system of a residential multi-storey building. The aim of the study was to increase the energy efficiency of heat supply systems by installing a single-phase heat storage. Tasks that were solved during the study: 1. Review of existing heating systems. 2. Construction of a calculation model of a single-phase heat storage. 3. Assessment of energy efficiency. 4. Comparison of various heat storage materials. As a result, a calculation model of a single-phase heat storage device and a list of initial data for it were presented, and was given an example of calculating such a storage device for a certain multi-apartment building and a comparison of two heat-accumulating materials. Based on the results, a choice was made in favor of concrete, as a body-accumulating material. It is worth noting that before that the issue of using single-phase heat storage devices in the heating system for the whole building was not considered. Economic efficiency with the use of such drives is achieved by charging at a cheaper rate (at night), and the consumption of stored energy in the remaining time of the day.

Lemeshko; Sherzod K. Khaldarov;Relevance. The power provided by generating stations based on wind and solar energy depends on the state of the environment at a particular geographical point, the prevailing wind speeds and the level of solar insolation. The wind speeds and solar insolation characterizing patterns are probabilistic in nature and depend on the terrain and season. This means that the power provided by generating stations based on renewable energy sources is also probabilistic. Risks associated with an inaccurate knowledge of the probabilistic patterns describing renewable energy sources, as well as the unpredictability (uncertainty) of the natural environment affecting renewable energy sources, are the reasons why system operators do not take into account such stations in calculating the power balance. This situation does not allow considering the generating stations as full-fledged market participants, covering the flow of investments in such projects. Accurate determination of the output power distribution laws for solar and wind power stations, based on the wind speed and solar insolation data analysis can significantly help system operators in power predicting of the power stations. Aim of study is building models of distribution laws that best describe the results of wind speed and solar insolation observations, as well as models of distribution laws for the generated power of wind and solar stations. Methods: methods for estimating the parameters of distribution laws, methods for testing statistical hypotheses. Results. It is shown, that the 3rd kind of beta distribution laws and their mixtures describe the series of measured wind speed and solar insolation better in the territory. The same concerning the probability distribution of the wind and solar stations power. Distribution law models for wind speed, solar insolation and power of the corresponding stations are constructed. It is shown that on the basis of the law of the distribution of wind speed and the mathematical relationships that connect power with wind speed, good models can be constructed for the probability distributions of power of wind power stations. The models can be used as an auxiliary tool for power system operators to predict output power.

In nominal and close to them modes, power transformers have a fairly high coefficient of performance (COP). However, the efficiency of autotransformers depends on many factors due to their design features. In this study, the authors propose a method for improving the energy efficiency of autotransformers while optimizing the functioning of their cooling system in order to reduce operating losses for electric drives of pumps and fans of forced cooling systems using an autotransformer with a rated power of 125 MVA as an example. Вопросы внедрения эффективных мероприятий по снижению потерь при эксплуатации силового электрооборудования представляют практический интерес для электросетевых и промышленных предприятий. В номинальных и близких к ним режимах силовые трансформаторы обладают высоким коэффициентом полезного действия (КПД). Однако из-за конструктивных особенностей автотрансформаторов их КПД зависит от многих факторов. На примере автотрансформатора АТДЦТН-125000/220/110-У1 номинальной мощностью 125 МВ·А предложен способ повышения энергоэффективности при оптимизации функционирования их системы охлаждения с целью снижения эксплуатационных потерь на электроприводы насосов и вентиляторов систем принудительного охлаждения.
