Assessment of Impacts of Electric Vehicles on LV Distribution Networks in Turkey

Güven, Ali Nezih
This study proposes a methodology to analyze the impacts of Electric Vehicles (EVs) on Low Voltage (LV) distribution networks based on probabilistic models developed for the charging process of EVs. In addition to the battery charging characteristics, Gaussian distribution function for EV plug-in times and Weibull distribution function for daily travel times are utilized in simulations. Monte Carlo based load flow simulations are performed in order to evaluate the response of the LV networks to various EV and load scenarios and different multi-tariff mechanisms. The sample networks are investigated for branch overloads, excessive voltage drops and losses using a systematic reporting approach developed. This method guides the utilities to determine the necessary investments on LV networks and their associated time frames. The expected consumer reaction to different multi tariff systems can also be modeled to assess the economic feasibility of a new multi tariff system against necessary investments in the LV network.


Assessment of impacts of electric vehicles on low voltage distribution networks in Turkey
Temiz, Armağan; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2015)
The number of Electric Vehicles (EVs) has reached a substantial value all over the globe due to economic and environmental factors. The increasing penetration of EVs to the distribution grids urges the requirement to investigate the impacts of EVs on the planning and operation of distribution networks. Despite the fact that there are numerous studies discussing the impacts of EVs on distribution grids, a particular study concerning the Turkish distribution networks does not exist. Therefore, this study focu...
Multi-objective charging scheduling utilizing electric vehicle load models
Güzel, İven; Göl, Murat; Department of Electrical and Electronics Engineering (2022-1)
Utilization of electric vehicle (EV) load models can improve the performance of smart charging strategies, which increase the reliability of the grid by harnessing the flexibility of EV loads. This thesis presents methods for utilizing EV load models in real time stochastic charging control with single and finite system-time horizons. First, the drivers’ load models are found with kernel density estimation. A single system time horizon coordinated charging control algorithm is devised to ensure each EV is c...
Parameter Estimation of Electric Vehicles for Improved Range Prediction
Saglam, Berkay; Bostancı, Emine; Göl, Murat (2021-01-01)
© 2021 IEEE.In order to improve performance of range estimation of electric vehicles, parameters that affect energy consumption should be determined accurately. This paper presents a parameter estimation methodology for electric vehicles based on least squares method. In this study, the power and angular velocity of wheels are measured from the vehicle directly. In addition to those, the directional velocity data is extracted from the GPS signal, in order to avoid the parameter dependency between the angula...
Energy Optimal Controller for Electric Vehicles on Partially Icy Roads with Heuristic Skidding Compensation
Ahiska, Kenan; Özgören, Mustafa Kemal; Leblebicioğlu, Mehmet Kemal (2015-10-16)
In this study, a mathematical model is constructed for an electric vehicle. An energy optimal controller is designed for the gross motion model of the vehicle moving on a positive constant slope road with some icy parts. The energy optimal controller takes torque, speed and battery constraints into account. The loss of control during skidding period is compensated with an additional control command based on heuristics. The compensation is based on an enrichment of applied control input throughout the sectio...
Optimal allocation of sectionalizing switches in rural distribution systems
Daldal, Mustafa; Özay, Nevzat; Department of Electrical and Electronics Engineering (2011)
The distribution system which forms the final connection between customers and power source plays a vital role in an electrical network. Different studies show that substantial proportion of the customer interruptions occurs due to the failures on distribution network. The ongoing privatization process of the electrical distribution services in Turkey raises the importance of reliable and continuous electricity supply significantly. The new regulations come up with this privatization process and the electri...
