Operating modesof solar and wind power plants directly depend on external uncontrollable factors - solar and wind activity. An additional feature of the planning of the wind and solar power plants operation modes is their instantaneous termination of power output in the event of the disappearance of the wind or the sun, respectively. Therefore, the termination of the power output is a “failure”, which creates an imbalance of active power in the system. To cover it, it is necessary to place active power reserves at the thermal or hydro power plants in advance, and the value of this reserve should be equal to the capacity of the largest wind and/or solar power plant. Systematic and consolidated information on the composition, quantity and installed capacity of wind and solar power plants in the United power system of Russia is not published in the public domain. Therefore, the purpose of this study is to establish the quantity and installed capacity of wind and solar power plants, as well as to identify the most powerful wind and solar power plants in Russia.","PeriodicalId":260032,"journal":{"name":"2021 Ural-Siberian Smart Energy Conference (USSEC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125008253","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}

In the known methods, the coincidence of the considered traveling wave front polarity with the first one is used as a criterion for selecting the traveling wave reflected from fault. The criterion is based on the assumption that the characteristic impedance of the electrical system adjacent to the protected power line is less than the characteristic impedance of the protected power line. In many cases, this assumption is justified, but there are examples of electrical systems in which this condition is not met. In such systems, the mentioned methods lose their performance due to incorrect criterion for selecting the traveling wave, reflected from the fault. This paper proposes an adaptive single-end traveling wave fault location method, based on taking into account the ratio of the characteristic impedance of the adjacent electrical system and characteristic impedance of the protected power line when identifying the traveling wave reflected from fault.","PeriodicalId":260032,"journal":{"name":"2021 Ural-Siberian Smart Energy Conference (USSEC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115424456","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}

Typically, when developing and testing regression models based on machine learning, their accuracy is calculated over a long time interval, from several months to several years, and then is averaged. However, in the real-life operation of such systems, the customer is likely to draw a conclusion about the system efficiency based on the results of the first 2–4 weeks of operation. If one or several large errors appear on this short interval, they will not be averaged as it happens over a long one. As a result, there is a risk of failure in the intelligent forecasting system implementation due to the discrepancy between the calculated mean error and that obtained over a short time period at the start of operation. This study considers the problem of solar power plant generation short-term forecasting, analyzes the distribution of errors over short time periods, and substantiates the need to use more detailed accuracy metrics of machine learning models than the error values averaged over a long interval.","PeriodicalId":260032,"journal":{"name":"2021 Ural-Siberian Smart Energy Conference (USSEC)","volume":"458 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125954028","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}

Previously, developed algorithm of the adaptive heavy-loaded trajectory identification makes it possible to identify the heavy-loaded trajectory using a current power system digital model relatively to a current power system state. The algorithm, in calculating limited active power flows in terms of small-signal aperiodic stability and monitoring small signal aperiodic stability violation in the researched controlled section precisely, uses such criteria as voltage levels at the ends of researched and adjacent controlled sections connections, as well as normalized angles through these connections. A software implementation of the adaptive heavy-loaded trajectory identification algorithm is performed using the object-oriented programming language C# in the development environment Microsoft Visual Studio applying AstraLib library of RastrWin3 software. The program is tested at controlled section No.1, which is the part of 500 kV transit of the chain structure. Calculated values of limited active power flows manually and using the program applying the adaptive heavy-loaded trajectory identification algorithm differ by 62 MW or 2.3%, which does not exceed 5% error value. Developed “Adaptive heavy-loaded trajectory identification” program allows calculating values of limited active power flows for a current power system state automatically. A promising direction of the program development is decreasing the running time of program operation and program modification for the identification of the adaptive heavy-loaded trajectory in circular and multi-closed structures.","PeriodicalId":260032,"journal":{"name":"2021 Ural-Siberian Smart Energy Conference (USSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129754702","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}

The paper considers Ekaterinburg (a city in Russia), which is the capital of the Urals. One of the factors ensuring the dominance of this city and its development is the presence in Ekaterinburg of a company that provides the management of the united energy system of the region. It is “United Dispatch Control of Urals”, part of the “Russian Power System Operator” company. The functions of the system operators, both direct and indirect, are considered, such as interaction with universities and research centers, participation in educational activities, job creation. An analysis of Ekaterinburg from the point of view of the labor market, characteristics of the energy system of the Sverdlovsk region (the capital of which is Ekaterinburg) was carried out.

To solve this problem, one of the possible approaches is the use of digital platforms. Its purpose is to provide a toolkit to reduce time-to-market for EMS.
