Electronic differential is utilized in EVs due to some drawbacks of traditional mechanical differential such as being heavy and bulky systems which are not convenient for EV, and mechanical losses caused by the powertrains. In this study, an EDS for front wheels of an EV with in-wheel motor is modelled instead of rare wheels which has commonly been studied in the literature. The front wheel speeds are estimated by equations derived from Ackermann-Jeantand model using Codesys Software Package. Then, the simulation of EDS is also realized by Matlab/Simulink. According to the change of the vehicle speed and steering angle of EV, front wheel speeds estimated by Codesys are verified by Simulink results. It is observed that the modelled EDS is appropriate for EVs with in-wheel motors.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115508711","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}

EV presents economic and environmental advantages over traditional gasoline vehicles. However, a number of EVs, if charged simultaneously, may pose some serious challenges for electric utilities especially at the distribution level. This paper investigates selected EV charging strategies to mitigate the adverse effect of charging EV on the peak demand. These charging strategies are implemented for different EV penetration levels and charging modes. Simulation results indicate that EV charging time, charging power and penetration levels are significant factors impacting system peak load. Examining different EV charging strategies can help reduce the negative impact of EV penetration on the peak demand and thereby improve system load factor.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129114597","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}

Hardware design of the electric motor control unit (EMCU) complies with the automotive hardware design standards. The software architecture of the EMCU is an AUTOSAR compliant real-time operating system (RTOS) based structure which enables easy integration of different function components and ensures safe hard real-time operation. Together with the RTOS on the 32-bit main microcontroller, an 8-bit support microcontroller is used to implement the functional safety requirements derived from analysis according to the ISO26262 automotive standard. The modular software structure also decouples the algorithm and interface development stages, making both hardware and software development processes less error-prone. To test the EMCU, a generic vector control scheme is implemented on the PMSM. Experimental results presented in the paper are acquired from tests on a full-sized ETAS HiL simulator setup consisting of a real-time PC and a configurable FPGA-based PMSM emulator board.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115630499","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}

Sunlight should fall with steep angle to extract maximum power from PV panels. Therefore optimum fixed tilt angles of PV panels should be changed monthly and seasonally. In the mathematical analysis of the study, the monthly, seasonal and the annual optimum fixed tilt angles of PV panels depending on solar angles are calculated for Bilecik city. In the experimental study, optimum fixed tilt angles for May, June, July and August are determined by PV panels placed at 10°, 20°, 30°, 40°, 50° and 60° tilt angles.

In this study, insulator leakage currents are simulated with the help of Ant Colony Algorithm (KKA). The pollution layer accumulated on the insulator surface is accepted as pheromones substances of the ants. In regard with this approach, the movement of ants, which are determined based on voltage of each point on the insulator surface, depends on amount of pollution and distance between these points. In the ant colony algorithm, pheromone substance is laid down to the trail of ants randomly and the amount of pheromone is constantly updated by multiplying with a coefficient of evaporation in order to take the evaporation into account. Similarly, the pollution layer on the insulator surface is distributed irregularly and evaporation coefficient is used to refer to a reduction in the amount of pollution caused by formation of dried bands. These bands are caused by the effect of heat produced by the flow of leakage current. The surface conductivity is calculated from the value of pheromone and the leakage current is calculated from conductivity and voltage difference between points by employing a computer software developed in accordance with this algorithm.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251160","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}

This paper aims to fit electricity price behavior to a statistical distribution in order to help market participants. We used a couple of statistical distribution functions in this study to determine electricity price behavior. The historical electricity price data were obtained from the website of PMUM, which consisted of hourly prices. Analyses were carried out for different intraday demand levels in different periods.
