The development of the electric grid system in the structure of Smart Grid requires more informatization. Under such conditions, become important components energy monitoring systems and the status of power transformers. This process is even more important in the case of transformers that have been in operation for a long time, and sometimes outside regulatory terms, which is typical of state networks. In most cases, the existing studies is based on the spectral composition analysis a transformer windings phase current and voltage. The procedure of determining the active and reactive power components of a three-phase transformer in idle mode, as indicators of the state of the active parts, taking into account the harmonics of current and voltage, is proposed. An experimental study of the transformer idling mode was carried out on the laboratory equipment. The primary sequence of the experimental study energy performance a three-phase transformer in idle mode is developed. For this purpose is use Fourier transform, and the active and reactive power index of windings are monitoring is determined by the fundamental harmonics of current and voltage and all measurements harmonics. It is noted in one of the phases that the higher harmonics power generation is provided when the star-delta is connected. In the same case, the current harmonics are greatly enhanced relative to the voltage harmonics. The study results can be used as components of information support for the Smart Grid structure.","PeriodicalId":169630,"journal":{"name":"2020 IEEE 7th International Conference on Energy Smart Systems (ESS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132905915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intermittent sources like solar, wind, and tidal power plants exhibit fluctuating power production that create an imbalance between generation and load. In this regard, renewable dispatchable sources like hydropower, geothermal, nuclear, and biomass based plants together with fossil fuel based plants play a significant role in balancing out the variability caused by intermittent sources. Smart energy systems maximize the use of intermittent sources while balancing generation and load with dispatchable sources. In this paper, an overview of smart energy systems is given, with main focus on renewable dispatchable sources. The need for model based analysis is emphasized, which leads to multiphysics problems. Multiphysics simulation languages and libraries are presented. Particular emphasis is put on the Modelica language and relevant libraries such as OpenHPL for hydropower modeling. A case study of the Trollheim Hydropower plant in Norway is presented. In addition, OpenHPL and the photovoltaic PVSystems library for solar power plants are combined to see how hydropower can be used as a dispatchable source for balancing out the variability caused by solar power plants in the interconnected grid of smart energy systems.","PeriodicalId":169630,"journal":{"name":"2020 IEEE 7th International Conference on Energy Smart Systems (ESS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129185302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the moment, in order to assess the reliability of power supply in local systems with renewables, there is a large number of indicators that are not directly related to each other. Reliability is one of the key concepts in electricity. The reliability of the power system is a feature of the continuous supply of electricity to consumers to meet their needs. The concept of reliability includes such features as failure-free, durability and maintainability. But this terminology has not become commonplace, it has not embraced or streamlined many terms for reliability. Thus, many authors use the concepts of structural, mode (functional) and balance reliability. This separation is conditional, first, to simplify the solution of the task of assessing the reliability of complex networks, and secondly, based on quantitative assessments of the components, measures can be taken to improve the level of reliability. Changes in energy sector related to the implementation of market relations and distributed generation require an update of terminology that can be used to decompose the reliability assessment task. Because assessing the reliability of distribution grids in today's environment is quite a challenge. The purpose of the article is to analyze the reliability of power supply for local systems with renewabes. One of the main issues in this topic, despite the large amount of research work involved, is the uncertainty of the method for calculating the reliability of power supply in Microgrids. The paper assesses the reliability of power supply and proves the need to introduce new indicators for local systems with renewables, since distributed energy sources, including renewables, affects systems reliability. Such indicators will allow assessing the reliability by each factor individually, and will show the impact of each factor on the overall state of the system.","PeriodicalId":169630,"journal":{"name":"2020 IEEE 7th International Conference on Energy Smart Systems (ESS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131740646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it should be noted that the optimal operation of the internal combustion engine is possible at a certain engine speed. A decrease in the engine speed leads to a deterioration in the filling of the fuel-air mixture and the exhaust of the engine, accompanied by an intake of exhaust gases into the intake manifold and the ejection of part of the combustible mixture into the exhaust pipe. The paper presents the general concept of creating a control system for an autonomous power source based on an internal combustion engine and an inverter. The expediency of adjusting the opening and closing angles of an internal combustion engine that works as a source of mechanical energy of an autonomous source of electrical energy is proved. The use of this system allows to reduce unit costs by 2 times when generating electric energy. Based on the gas distribution diagram of the internal combustion engine, the dependence of the change in the opening and closing angles of the intake and exhaust valves on the power of an autonomous energy source is proposed.","PeriodicalId":169630,"journal":{"name":"2020 IEEE 7th International Conference on Energy Smart Systems (ESS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115713578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
