This paper presents an optimisation methodology for simulating the integration of distributed generation and electric vehicles (EVs) in a residential district. A model of a smart residential district is proposed. Different charging scenarios (CS) for private cars are considered for simulating different power demand distributions during the day. Four different case studies are investigated, namely...
The reduction of air pollutant emissions for the resolution of preserving and improving air quality across the world is a major concern to which all current governments are assigning significant amounts of commitments and resources. The effective improvement of air pollution involves strategic investments in the commercialisation and adoption of clean energy technologies by both private and public...
In the face of energy crisis and environmental pollution problems, all the countries in the world vigorously promote the development of electric vehicles. Electric vehicle charging infrastructure is the necessary infrastructure to the development of electric vehicles. This work has been focused on Electric Vehicles' Charging Stations (CSs) deployment. It has been considered in this study several constraints...
Electric mobility is assuming a central role in the new world energy scenario where Renewable Energy Sources (RES) have increased their contribution to the electricity production, mainly due to the fact they are characterized by a reduced environmental impact; in the aforesaid context, Electric Vehicles (EVs) can play a significant role to facilitate the integration of RES into the power grid, also...
The transportation sector is greatly responsible for air pollution. Therefore, electric vehicles can play an important role in the near future in order to improve the air quality in cities and metropolitan areas. In general, we cannot assume that the electricity for charging batteries is only generated by renewable energy sources. For this reason, the aim of this work is to present the development...
The railway market increasingly requires a longer useful life for the vehicles and a reduction of the maintenance operation, as well as the better prediction of possible failures of the various components. In this context, sensible components are the signal connectors used to transmit information along the train both in fixed and in detachable configuration. Therefore, the paper, after a brief analysis...
In 2008, the European Commission published the climate and energy package “20 20 20” with the objective of reducing the greenhouse gas (GHG) emissions and increasing the production from renewable energy sources (RES) and the energy efficiency. Electric Vehicles (EVs) contribute to lower the GHG emissions as they produce no exhaust gas as opposed to internal combustion engine (ICE) vehicles. The present...
Even though the role of regulatory policies in the electricity market supporting the diffusion of distributed generation and energy efficiency has been well investigated, the relationship between changes in electricity tariff and the impact on investments in RES and Energy Efficiency Measures (EEM) has been under researched in academic literature so far. The paper is a first attempt to analyze how...
In recent years, the strong growth in solar power generation industries is requiring an increasing need to predict the profile of solar power production over the day, in order to develop high efficient and optimized stand-alone and grid connected photovoltaic systems. Moreover, the opportunities offered by battery energy storage systems coupled with PV systems, require the load power to be forecasted...
The need to reduce pollution, relatively low cost of ownership, and the recent news about exhaust fumes emissions tampering have the potential to increase electric car sales. However, electric cars also need a network of fast charging stations to allow a quickly recharge when driving relatively long routes. This could be achieved by locating charging station for instance in motorway service areas...
Home Automation systems represent one of the most promising technologies for energy efficiency, which is currently considered one of main factors enabling an environmental sustainable growth. However, several barriers hinder a massive diffusion of Home Automation systems and their economic viability. The paper aims to analyze the economic viability of the adoption of a Home Automation system in different...
Nowadays, the transition to a more sustainable energy and transport system is necessary. This work faces this theme at a district level, considering a residential neighborhood of a big metropolitan area and proposing a model for a Smart Residential District. The optimum quantities of installed power are calculated thanks to an optimization procedure based on a Genetic Algorithm: a non-deterministic...
Today there is a huge debate about the diffusion of electric vehicles (EV) to reduce air pollution and the countries' dependence on fossil fuels. The aim of this work is to estimate the environmental impact that the diffusion of EV may have in Italy. Notwithstanding the penetration of EV in the Italian market is still negligible, policy makers consider the massive diffusion of EV as a valid answer...
The goal of this work is to predict e-mobility trends which are essential for understanding the market and the infrastructure development over the next years. Nowadays among the many and different standards and rules there are two charging categories for electric vehicles: high power DC and AC charging modes. It will be interesting to see which technology will prevail in the next few years and if...
Renewable energy sources (RES) are expected to be essential assets in the future smart grid. The impact of renewable energy sources in the electrical grid mainly depends on their nature, their penetration rate and the topology of the grid. This paper addresses how a representative power quality parameter (the number of voltage dips) are affected by the inclusion of renewable energy sources. Specifically,...
The world is facing an urgent need to reduce emissions, limiting pollution for a better quality of life. This objective has to be reached by all cities and governments worldwide. This paper focuses on the field of transportation, which is greatly responsible for air pollution, mainly in cities and urban areas such as towns, airports and seaports. The diffusion of electric vehicles (EVs) enables a...
The HVDC transmission is employed to transmit high amount of power through long distances, to overcome the limits of the AC transmission in terms of power flow regulation. Furthermore, the HVDC transmission is also involved in the connection of renewable energy sources, such as high power solar panels, wind farms, etc. In particular, this paper deals with the fault detection method in HVDC transmission...
Today, innovative Smart Grids work in synergy with Electric Vehicle (EV) infrastructures, not only for a sustainable mobility, but also for their flexibility in supporting the electric grid. These technologies are adopted by many institutional and university campuses to reduce the primary energy consumption, increase the renewable source exploitation and provide a green mobility. The aim of this work,...
Today, the concept of Smart Grid is very often strictly related to Electric Vehicles (EVs) infrastructures. EVs have not gas emissions, they have silent driving and much higher efficiency than internal combustion engine vehicles and, in particular, they are fundamental for the world's sustainable mobility. In fact, many industries and universities have decided to replace their corporate fleet with...
The microgrids can function as a single controllable system in a grid-connected or islanded operation mode. The transition from grid-connected mode to islanded mode can result in microgrid excess generation or demand, which must be spilled or curtailed. This paper proposes an optimization model for optimizing the microgrid operations accounting for distributed energy resources (stochastic generation...
