Implementation of a Management System for Prosumer Energy Storage Scheduling in Smart Grids

2020

Scheduling of energy storage systems of distributed generation is a key element for optimal renewable energy sources (RES) exploitation in smart grids, demand side response strategies implementation and prosumers interaction with Distribution System Operators (DSOs). In this context, this paper presents the implementation of a management system for energy storage scheduling, which allows taking appropriate account of the storage system behavior in real cases. To properly consider the real system operation, the employed battery model is modified, in order to include also the hysteresis phenomena in state of charge estimation in both charging and discharging operation. The validation of the p…

Efficiency optimization in bi-directional inductive power transfer systems

2015

Inductive Power Transfer (IPT) allows to wirelessly supply electronic devices. Thus, it is a very smart technique of battery charging for electric vehicles. In a parking area scenario, IPT is a proper method aiming at the energy transfer from the vehicle battery to the electric grid too. Bi-Directional Inductive Power Transfer (BDIPT) Systems are an attractive solution for the automotive market. Due to the great relevance of the energy saving problem, the goal of an efficiency maximization is researched by the energy market. In this paper, an in-depth investigation of the power efficiency in BDIPT systems is carried out, aiming at the optimum efficiency.

Life cycle assessment of storage systems: the case study of a sodium/nickel chloride battery

2014

This study assesses the energy and environmental impacts of sodium/nickel chloride batteries, one of the emerging battery technologies for energy storage and smart grids. The analysis was conducted using the Life Cycle Assessment methodology according to the standards of the ISO 14040 series. The study system was one sodium/nickel cell battery providing electric storage for a photovoltaic system, and the manufacturing, operation, and end-of-life steps were analysed. The results indicated that the operation step has the greatest energy impact (55-70% of the total), with the manufacturing step, particularly cell manufacturing, contributing the greatest environmental impact (>60% of the total)…

Investigation of inductive coupling solutions for E-bike wireless charging

2015

Wireless charging of electric vehicle batteries is a major topic for academic and industrial research. The wireless charging is based on the inductive coupling between a primary coil, connected to the grid, and a secondary coil, connected to the vehicle battery. Wireless battery charging provides benefits in terms of comfort for the drivers, who should just park to start the charging operation, without needing to plug in the vehicle. Wireless charging is particularly convenient for E-bike users. For the bicycle charging, the inductive coupling should be implemented through a compact and light-weight solution. In this paper, different options of inductively coupled coils for E- bike charging…

Wireless battery charging for electric bicycles

2017

The contactless solution is increasingly spreading as method of battery charging for Electric Vehicles (EVs). The standard technology of contactless EV battery charging is based on the Inductive Power Transfer (IPT) between two coupled coils, one connected to the electrical grid and the other one connected to the rechargeable battery. The IPT provides benefits in terms of safety and comfort, due to the absence of a plug-in operation. In this paper, an overview on the IPT applied to the battery charging of electric bicycles is provided, with some general considerations on the technical implications. Moreover, a prototype of contactless battery charging for E-bikes is proposed and described.

A heuristic approach for optimal operation of grid connected source-battery-load systems

2016

In the paper an optimal management procedure for a system composed of a renewable energy source, storage batteries and a load, permanently connected to a distribution network, is presented. The issue follows two objectives: a) maximum economic benefit for the system, and b) minimum energy exchange with the network. The operation cost of storage facilities, as well as the technical and economic constraints on power exchanges between the system and the network and the technical constraints about charging and discharging cycles of the batteries are considered. The effectiveness of the management procedure is numerically tested and the results are presented.

Analysis of a Fast Reserve Unit Behaviour with Additional Modular Synthetic Inertia Control

2021

The paper presents the results of a theoretical study on the behaviour of a battery storage system operated as a Fast Reserve Unit and equipped with additional synthetic inertia control. The Fast Reserve Unit is assumed connected to the transmission system of Sicily, operated as an isolated grid in order to show more clearly the effect of the Fast Reserve Unit intervention during a power imbalance. The unit is controlled also to provide synthetic inertia with a conventional control scheme and with a new scheme proposed by the authors and named “Modular Synthetic Inertia”. The latter has been conceived for offering a modular response as a function of the Rate of Change of Frequency, to avoid…
