The construction of a decentralized energy system can have technical and economic reasons. It may be a technical reason that the consumer requires that are not available by connecting to a wired network. If a consumer decides to install his own power generating unit and becomes a “prosumer”, a preliminary technical and economic analysis of it is necessary. The design of the system, as well as the most optimal operating strategy for the system, must be determined during the technical examination. During my research, a simple unit cost analysis of a cogeneration system was performed. The aim of the research is to determine the costs of both electricity and heat production, and then to draw economic conclusions in comparison with the fixed tariffs. In the course of the examinations, I also discuss the role of the investment and operating costs of the unit costs. Possible economic planning principles are determined for combined heat and power gas engine unit.","PeriodicalId":226881,"journal":{"name":"2019 7th International Youth Conference on Energy (IYCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127928891","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 these systems, transients challenge the vehicle developer, in terms of their impact on the protection, measurement and the communication systems. A transient occurs while connecting a vehicle to the infrastructure at the beginning of a charging procedure. In this paper, a summary of the effects of voltage and current transients on the automotive HV supply systems is shown. A detailed system level modelling approach is provided to examine the electric transients on automotive HV-systems. The critical design and integration challenges are analysed with respect to reliable and stable operation. Furthermore, the relevant electrical characteristics on device and system level are evaluated to guarantee the safe and stable operation of the automotive HV supply systems.

Using the information revealed, dioxin and carbon dioxide emissions are observed. The former is compared with cigarette smoking, the latter with the emission of gas fueled heating systems in Hungarian households.

One example of such a device that utilises this effect is called an ionic flyer. The device has no moving parts, no combustion emissions and near silent. The Biefeld-Brown effect causes the flyer to be able to float in the air. The thrust that causes the device to float is created by the application of high voltage dc across a capacitor configuration resulting in an ionic wind, creating a net force from the negative toward the positive terminal. An investigation is undertaken to determine if the Biefeld-Brown effect could be used to create a lifting effect on an aircraft wing and as such aid flight. A model aerofoil wing was tested in a wind tunnel under the application of high voltage dc in order to reproduce the Biefeld-Brown effect. This paper outlines the tests that were conducted in the wind tunnel on a wing aerofoil model, as well as the empirical measurements taken. Results are analysed and arguments presented on the potential benefits of using the Biefeld-Brown effect on fixed wing aircraft.","PeriodicalId":226881,"journal":{"name":"2019 7th International Youth Conference on Energy (IYCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129937418","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 Ideal Transformer Model algorithm is one of the most straightforward methods for hardware-in-the-loop simulations. Integration of the Ideal Transformer Model into the system does not affect systems impedance characteristics and this is its most prominent advantage. However, specific change of system and load impedance ratio may result into system instability. Furthermore, it is shown that the transition of the system into an unstable state is the consequence of the time-delay between simulators. Time-delay turns out as a disturbance that amplifies an error due to transmission of the voltage signal between the simulators. Taking into account Nyquist stability criterion, three cases with different system and load impedance ratio are presented, first with the simulations in Matlab Simulink and later on with simulations on RT simulators.","PeriodicalId":226881,"journal":{"name":"2019 7th International Youth Conference on Energy (IYCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122351214","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}

Due to its outdoor installation, it is exposed to all sorts of climatic stresses, such as mechanical, ultraviolet radiation, temperature, and humidity stresses. Safe and reliable operation of the photovoltaic systems is highly dependent on the DC cables installed between the photovoltaic modules and inverters. Since these cables not only carry the load current but are also exposed to the external harsh environment and hence are more vulnerable to degradation. This research has been aimed to study the aging of low voltage photovoltaic DC cables under thermal stress. The cable samples are thermally accelerated aged and the electrical integrity of these cables are studied by the dissipation factor and capacitance measurement in the frequency range of 20 Hz to 500 kHz. The results show that because of aging the dipolar polarization has been affected. Also, the minimum value of the dissipation factor has significantly decreased at lower frequencies, in addition, the shifting of the minimum value of dissipation factor to lower frequency with the aging has also been observed.","PeriodicalId":226881,"journal":{"name":"2019 7th International Youth Conference on Energy (IYCE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122412621","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 recent years, several methodologies based on computer algorithms and mathematical formulation have been proposed for solving optimal reactive power dispatch. The techniques are classified based on conventional and intelligent methods. The objective of this paper is minimization the power losses using intelligent algorithms like Particle Swarm Optimization method and conventional method like Newton Raphson. Particle Swarm Optimization (PSO) is based on the simulation the act of group of fishes or birds in searching space for finding optimal solution as the piece of food. The proposed algorithms are analyzed on the Nordic 44 system. The results of simulation show the reduction of total power losses using intelligent method.
