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 focuses on analyzing the impacts of EVs on low voltage distribution networks in Turkey. Three distribution network models, two of them belonging to actual Turkish distribution network segments and one being generic, including different customer attributes and network structures are constructed and utilized throughout this study. An extensive EV model is developed using probabilistic models and assumptions. Gaussian distribution function for EV plug-in times and Weibull distribution function for daily travel times are adapted in Digsilent PowerFactoy simulation tool.Monte Carlo based load flow simulations are performed in order to evaluate the response of the distribution networks to various EV and load scenarios considering different multi-tariff mechanisms. Furthermore, a methodology is developed to obtain and present network results based on transformer and cable overloads, voltage drops, and grid losses. This methodology will help the decision maker determine the necessary investments on the distribution networks and associated time frames. This approach will improve the planning process of distribution companies. Hence, distribution companies will submit more realistic and accurate investment plans to the regulatory agencies.

Assessment of Impacts of Electric Vehicles on LV Distribution Networks in Turkey
TEMIZ, Armagan; Güven, Ali Nezih (2016-04-08)
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 a...
Monte Carlo based control algorithm for economic feasibility of V2G applications
Şahinkaya, Kıvanç; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2019)
The use of electric vehicles (EVs) has been increasing in recent years due to economic and environmental factors. This rapid development makes it necessary to investigate the effects EVs on the power system planning and system participants. The aim of this study is to determine the optimal operating strategy for a microgrid operator which can function as a prosumer with the contribution of vehicle to grid (V2G) application. The connection time, plug-in time and state of charge (SoC) of EVs are stochastic va...
An improved energy requirement prediction for queueing applications of electric vehicles based on parameter estimation
Sağlam, Berkay; Göl, Murat; Department of Electrical and Electronics Engineering (2022-8)
The use of electric vehicles has increased in recent years. Although they have many benefits to the environment such as reduced carbon emissions, charging of vehicles brings some new challenges for power systems such as overloading, reliability problems, etc. Charging of electric vehicles should be managed to overcome these problems. Queueing strategies are one of the management methods. These strategies are applied to obtain a feasible operation that depends on the decisions made considering system propert...
Optimal Battery Sizing for Electric Vehicles Considering Battery Ageing
Gezer, Ali; Ünver, Baki Zafer; Bostancı, Emine (2022-01-01)
Due to environmental issues such as emission of carbon gases and depleting natural resources, Electric Vehicles (EVs) are attracting more attention. To make EVs viable and widespread, the batteries' high cost and performance degradation problems have to be overcome. The degradation of the battery both in terms of energy capacity and power capability is highly dependent on conditions of utilization. To understand the relationship between energy utilization and battery size, an electric vehicle model that is ...
Optimal phasor measurement unit (PMU) placement for the power systems with existing SCADA measurements
Ertürk, Bulut; Göl, Murat; Department of Electrical and Electronics Engineering (2017)
It is extremely important to maintain efficiency, sustainability and reliability of the generation, transmission and distribution of the electrical energy; hence it is mandatory to monitor the system in real time. State estimation has a key role in real time monitoring of a power system. The considered power system has to be observable in order to perform state estimation. Traditionally, power system state estimators employ SCADA measurements. However, as the number of Phasor Measurement Units (PMUs) increa...
