The cost based approach is presented in this paper. It allows to make optimal choice for the Microgrid structure depending only on the local prices on the market. The demand side management concept is used to optimize the behavior of Microgrids in the electricity market. To do this time-of-use tariffs are presented as highly effective demand-response programs for Microgrids with DG sources. Tariffs that change over time allow to respond to demand in the market. Such tariffs stimulate load regulation, both manually and automatically, which allows consumers to save on electricity costs, while enjoying the benefits of the system. The purpose of this paper is to present cost based DSM methods for the Microgrids with Distributed Generation sources to optimize their operation.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"4 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120835856","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, a primary concern is that the rates of electric to kinetic energy conversion efficiency are typically found to be less than 1%. In order to determine feasibility of EHD propulsion in an atmospheric medium, potential ways to increase efficiency, thrust, thrust density, and decrease thrust to power ratios must be considered. A theoretical increase in EHD electric to kinetic conversion efficiency from less than 2% up to 22% has been previously suggested by Singhal & Garimella (2005) as a function of bulk fluid velocity. At sufficient velocity, the total combined output fluid efficiency was theorized to be greater than those expected from mechanical and electrical systems individually, possibly due to convection currents. The proposed experimental setup has the benefit of being straightforward and robust, and the power input and output of each individual mechanical and EHD system of the thruster can be observed and measured as they operate separately, and then in a combined manner as a system.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123541906","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 thermodynamic model of unsteady heat transfer during molding of the polymeric composite material in the heated tools has been developed. The model allows obtaining the temperature distribution over the thickness of the system under study, evaluating the influence of the exothermic effect of the binder curing reaction, and determining the required power of the heating system. It is shown that energy saving for the heated fiberglass shape-generating molding tools is from 40 to 60%. Analysis of the influence of mechanical characteristics of the material of the molding tools on energy consumption has been carried out. Fiberglass has the lowest energy consumption; heating of the aluminum and steel tools of similar purpose will take 20% and 45% more power, accordingly. Dependencies of the heating system parameters on the various conditions of heat transfer (air circulation rate in the room and heating rate) are shown. The final stage of the study involved creating an experimental prototype of the portable heating equipment of the shape-generating molding tools for the manufacturing of structures of polymeric composite materials.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115330137","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}

Averaged mathematical models of boost, buck and buck-boost converters have been developed, allowing the analysis of steady-state processes in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It is shown that a new approach to obtaining averaged models makes it possible to calculate not only the constant components of the process, but also their pulsation components, as well as the duration of the time intervals of the steady-state process, which is an advantage over traditional averaging methods. Using the obtained models, the dependences of the current ripple of the storage choke relative to the load current and the voltage transfer coefficient of the converters were calculated in the entire range of regulation of the switching duration.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122848284","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}
