Going forward to reach infrastructure grid by incorporating cluster of renewable and distributed energy sources, storage systems, different kinds of loads, in a huge dimension of information, communication and control technologies, has been established concept of “Smart Grid”. By jointly considering local distributed generation, i.e. two small wind turbines, PP load, i.e. fast charger of electrical...
A 15 kVA power electronic system with a battery energy storage system is presented in the paper. The system is designed for areas where a problem with the quality of the electrical power arises. The system is intended for households and small industrial facilities and provides a variety of functionalities such as: ability of providing high quality voltage for the customers load, uninterruptible power...
In the upcoming years, thousands of battery storage systems will be decommissioned from electric vehicles. Instead of recycling or sending them immediately to landfills, these battery systems could be reused in other applications, such as grid or end-user applications. Second-life batteries are still expected to be capable of storing and delivering substantial energy. It is possible that they could...
In this paper, we propose a comprehensive architecture based on vehicular communication technologies, considering vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. In addition, we present a study about EVs charging load. Our proposal addresses three main issues: (i) knowledge of the number of vehicles that are going to recharge their batteries at a particular point and instant,...
Electric mobility has gained much attention over the last years. The reason for this popularity is the hope that the electric powertrain may—one day—replace conventional combustion engines; including all the problems they cause. At first glace, this hope seems to be justified, on second thought, however, electric vehicles (EVs) do not appear as environment-friendly as they are supposed to. The problem...
The low-carbon society requires significant changes in the operation and planning of distribution systems. In order to exploit existing low voltage systems, Demand Side Integration is essential for offering services that increase security and quality of supply, improve energy efficiency and reduce the energy cost. The paper describes the three-year project e-visiØn, currently under completion, aimed...
To reach the 2020 targets proposed by the European Commission (EC), several smart grid advances must still be implemented at the distribution grid level. The Grid+ project has described these advances in the latest European Electricity Grid Initiative (EEGI) research and innovation (R&I) road map for smart grids. A good review of these research activities can be found at Grid4EU, which is a large-scale...
The simulation model of the Smart Grids Laboratory of the Institute of Energy and Transport is presented in this paper and a day of its operation is analyzed. The developed model simulates six different modules (a photovoltaic array, a Li-ion battery storage system, a small wind turbine, a diesel generator, a laboratory load and the connection point with the grid). The modules are connected radially...
This paper describes Nice Grid, a demonstration project part of the European initiative Grid4EU. The project aims at developing a smart solar neighbourhood in the urban area of the city of Nice, France. The four year project started in November 2011 and will test the suitability of recent developments in distribution networks management for facilitating the connection of distributed renewable generators,...
Despite a widely spread intuition about growing needs for energy storage solutions over the world, there is still no consented scenarios on the requirement for additional storage capacities within main power systems. Besides, storage value assessment and economics are mostly not proven yet in the frame of Smart Grids. The main objective of this paper is to highlight the need for coordinated energy...
