The simulation model implements the solution of differential nonlinear equations describing the dynamics of rotational motion of a two-mass electro-hydro-mechanical system. The mutual influence of one inertial component on another is carried out through the electrical connection between the wind turbine generator and the electric motor of the hydraulic turbine. The model takes into account the nonlinearity of the aerodynamic characteristics of the wind turbine from the speed and angle of rotation of the blades the nonlinearity of the hydromechanical characteristics of the hydraulic turbine from the speed. The results of modeling shown certify the reduction of energy efficiency of wind turbines during the accumulation of their energy at the pumped hydro storage station due to the presence of wind speed pulsations.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125830348","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}

By reducing the error in forecasting losses by 1%, this will reduce the cost of compensating for imbalances in the amount of 131.2 million per year, which will reduce tariffs for distribution and transmission of electricity. The study describes a comparative analysis of different architectures of artificial neural networks of deep learning for short-term forecasting of nodal electrical load. A comparison of the results of forecasting artificial neural network architectures and classical forecasting methods was performed. Data from the Northwestern region of the United States and Turkish power system were used. The results of the study show that neural networks of deep learning are superior to classical methods.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"23 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125840394","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}

Two different start-up schedules for real power plants are considered. They differ in the steam parameters and in the duration of some stages of start-up. A mathematical model for calculating low-cycle fatigue in high-temperature turbine rotors is presented. The calculation of the thermal and stress-strain state of the rotor in a non-stationary setting is performed. The areas of concentration of stresses in the rotor are established. It is established that when working on one of the start-up schedules, due to more uniform heating of the flowing part of the turbine and rational start-up time, it was possible to reduce the temperature gradients and the amplitude of stresses in most areas of the rotor. As a result, the permissible number of start-up cycles increased by 15.7%.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122313877","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}

There is also a steady upward trend in non-linear load, largely due to the transition to energy-efficient light sources. In this regard, urban cable networks operate at the limit of their capacity, which means operating with the maximum allowable core temperature limit. The problems of monitoring the temperature of cable insulation are an urgent problem in the electric power industry. One of the most promising areas of research is the development of methods for determining the residual lifetime of cable insulation, which can be calculated from monitoring temperature of insulation and other factors that significantly affect the insulation material. The paper analyzes the possible methods to monitor the cable insulation temperature. Mathematical equations are proposed for an indirect temperature monitoring system for cable using distributed measurements technology.","PeriodicalId":432063,"journal":{"name":"2022 IEEE 8th International Conference on Energy Smart Systems (ESS)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126318260","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}
