23. Wireless Power Transfer: Principles and Applications [Book News]

Author

Spagnuolo, Giovanni

Abstract

The book gives a comprehensive view of wireless power transfer (WPT) technologies, with a special emphasis on the multiple-pickup WPT. A number of applications is also described, including the systems employed in portable consumer electronics, in‐flight charging for unmanned aerial vehicles, underwater wireless charging, and the high‐power electrical vehicle (EV) wireless charging that has been already mentioned above. The book is organized in four parts, each one of them consisting of multiple chapters. The first part is divided into two chapters: an overview of several WPT technologies is given, but the main emphasis is given to inductive power transfer (IPT) technology. The second part of the book gives a view of the issues related to the design and optimization of coupled coils and power circuits.

Abstract

This paper proposes an energy management system (EMS) for a photovoltaic (PV) grid-connected charging station with a battery energy storage system (BESS). The main objective of this EMS is to manage the energy delivered to the electric vehicle (EV), considering the price and CO2 emissions due to the grid’s connection. Thus, we present a multi-objective two-stage optimization to reduce the impact of the charging station on the environment, as well as the costs. The first stage of the optimization provides an energy schedule, taking into account the PV forecast, the hourly grid’s CO2 emissions factor, the electricity price, and the initial state of charge of the BESS. The output from this first stage corresponds to the maximum power permitted to be delivered to the EV by the grid. Then, the second stage of the optimization is based on model predictive control that looks to manage the energy flow from the grid, the PV, and the BESS. The proposed EMS is validated using an actual PV/BESS charging station located at the University of Trieste, Italy. Then, this paper presents an analysis of the performance of the charging station under the new EMS considering three main aspects, economic, environmental, and energy, for one month of data. The results show that due to the proposed optimization, the new energy profile guarantees a reduction of 32% in emissions and 29% in energy costs.
