Abstract:

In this article, we propose a new method for determining the maximum load of electric consumers in urban electric networks, which differs from existing methods in more accurate and reliable determination of the maximum loads. Based on the determination of the maximum loads of the objects of urban electrical networks, it is concluded that the proposed methods are determined by high accuracy and minor errors.

Abstract:

The transport systems of the largest cities in Russia usually include extensive tram and trolleybus networks. There are subways in seven million-plus cities. Thus, electric transport has a very significant role in the passenger traffic of these cities. Moreover, the mentioned elements of the electric transport system can influence each other in different ways, and the level of their spatial interaction can also differ. For example, in global practice, there are cases when most types of public transport in the city (bus, trolley, tram, minibus, etc.) are feeders to subway lines, which are usual

Abstract:

A mathematical model is proposed to increase the reliability of power supply on the basis of reducing the technical cause of damage by the expressed relative probability of a flow of failure depending on power consumption. To test the adequacy of the proposed mathematical model, the data of daily winter and summer power consumption schedules are used to determine the dependence of the relative flow of failure from power consumption during peak hours.

One of the main tasks being solved for all electric networks with open topology, including city electric networks, viz. a task of the choice of optimum points of disconnection, has been improved. It is shown that saturation of urban networks with distributed sources of small-scale generation causes the fact that mode parameters being determined in the urban SMART GRID conditions become observable. Therefore, the majority of problems of mode control, typical for urban distribution electric networks of a traditional design, lose their relevance under the SMART GRID conditions.

Abstract:

The progressive substitution of traditional buses with electric ones in urban public transport constitutes a fundamental challenge towards sustainable mobility. This paper presents a methodological approach to assess energy consumption in urban bus networks, focusing on a city with varied topography and examining alternative bus lines for similar trips. Utilizing a quasi-static longitudinal model, real GPS data, and open access terrain models, the analysis aims to provide a nuanced understanding of energy performance, considering factors such as stop characteristics, gradients, and driving sty

Abstract:

In 2016, the Dutch government, in pursuit of the UN’s sustainable development goals, set a target that all its diesel transit bus networks should be fully electrified between 2025 and 2030. A research team from Rotterdam School of Management has since worked in close collaboration with Rotterdamse Elektrische Tram, the public transport operator in the city of Rotterdam, to accomplish this complex transition. This paper presents essential lessons learned and key practical implications derived from the project. As part of the transition process, we developed a discrete-event simulation model tha

Abstract:

Internet of Things, low energy consumption, and intelligent and functionally integrated urban infrastructure construction are crucial elements in the development of smart cities. Distributed generation (DG) and electric vehicle charging infrastructure play a vital role in the planning and construction of smart cities. However, the uncertainty associated with the power output of distributed generation significantly impacts the planning of distribution networks. To address this issue, this paper proposes a site-selection recommendation algorithm that leverages urban multimedia data and improved

Abstract: A machine learning-based framework for forecasting the energy efficiency of electric city buses is presented in this study. It is designed to maximize operational efficiency in public transportation networks. The foundation of this system is a specially created dataset that mimics actual operational situations. It includes variables like Passenger count, temperature, HVAC load, auxiliary load, and elevation change. Before the dataset is used to train multiple regression models, it is preprocessed and standardized. The Random Forest Regressor was chosen as the final model because of i

In the case of M-DTV, the electric field is calculated at user height, while for H-DTV it considers a fixed antenna on houses roofs. The field calculation is based on Geometrical Optics (GO) and the Uniform Theory of Diffraction (UTD). The results for M-DTV show a good agreement with measurement data in an Amazonian ci
