Book Description
Electric Vehicles (EVs) are emerging to play a key role in mitigating fossil fuel reliance and the environmental impacts brought on by the transportation sector. In parallel, it is essential that this growing electricity demand be met mostly with renewable sources. This study, as part of the Irvine Smart Grid Demonstration (ISGD) project, analyzes the effects of a renewable solar photovoltaic (PV) nanogrid --- a small-scale, autonomous power system, that ultimately ties into the central electrical distribution grid --- for EV charging associated with a controllable battery energy storage system, deployed in a primary circuit on the UCI (University of California, Irvine) Microgrid. The system's dynamic behavior is characterized for different control algorithms that govern battery dispatch, creating four different energy management strategies.Power quality aspects of EV charging are also investigated, with a focus on harmonic distortion. A robust system design using delta-wye grounded transformers was shown to prevent any excessive harmonic currents from flowing upstream into the microgrid. Additionally, a diversity of EV charging loads promotes favorable harmonic cancellation.A power flow model of the nanogrid was developed in a commercial power flow software (ETAP) and verified against smart meter data, which were used as inputs for the ETAP Real-Time module.Lastly, a linear program was developed for optimally sizing nanogrid assets in the context of minimizing operation costs for the microgrid operator. The combination of an 80 kW PV array and a 95 kWh/45 kW battery energy storage system was shown to be the best option to power 20 Level-2 (7.2 kVA) EV chargers deployed at one of the university campus parking structures.

Book Description
Electric vehicles are only ‘green’ as long as the source of electricity is ‘green’ as well. At the same time, renewable power production suffers from diurnal and seasonal variations, creating the need for energy storage technology. Moreover, overloading and voltage problems are expected in the distributed network due to the high penetration of distributed generation and increased power demand from the charging of electric vehicles. The energy and mobility transition hence calls for novel technological innovations in the field of sustainable electric mobility powered from renewable energy. This Special Issue focuses on recent advances in technology for PV charging and storage for electric vehicles.

Book Description
This is a reprint in book form of the Energies MDPI Journal Special Issue , entitled “Energy Storage Systems and Power Conversion Electronics for E-Transportation and Smart Grid”. The Special Issue was managed by two Guest Editors from Italy and Norway: Professor Sergio Saponara from the University of Pisa and Professor Lucian MIHET-POPA from Østfold University College, in close cooperation with the Editors from Energies. The papers published in this SI are related to the emerging trends in energy storage and power conversion electronic circuits and systems, with a specific focus on transportation electrification, and on the evolution from the electric grid to a smart grid. An extensive exploitation of renewable energy sources is foreseen for the smart grid, as well as a close integration with the energy storage and recharging systems of the electrified transportation era. Innovations at the levels of both algorithmic and hardware (i.e., power converters, electric drives, electronic control units (ECU), energy storage modules and charging stations) are proposed. Research and technology transfer activities in energy storage systems, such as batteries and super/ultra-capacitors, are essential for the success of electric transportation, and to foster the use of renewable energy sources. Energy storage systems are the key technology to solve these issues, and to increase the adoption of renewable energy sources in the smart grid.

Book Description
MICROGRIDS for COMMERCIAL SYSTEMS This distinct volume provides detailed information on the concepts and applications of the emerging field of microgrids for commercial applications, offering solutions in the design, installation, and operation of this new, cutting-edge technology. The microgrid is defined as Distributed Energy Resources (DER) and interconnected loads with clearly defined electrical boundaries that act as a single controllable entity concerning the grid as per IEEE standard 2030.7-2017. It provides an uninterrupted power supply to end-user loads with high reliability. Commercial systems like IT/ITES, shopping complexes, malls, the banking sector, hospitals, etc., need an uninterrupted input power supply with high reliability. Microgrids are more suitable for commercial systems to service their clients with no service discontinuity. The microgrid enables both connection and disconnection from the grid. That is, the microgrid can operate both in grid-connected and islanded modes of operation. The microgrid controller plays an important role in microgrid systems. It shall have an energy management system and real-time control functions that operate in the following conditions: both grid-connected and islanded modes of operation, automatic transfer from grid-connected mode to islanding mode, reconnection and re-synchronization from islanded mode to grid-connected mode, optimization of both real and reactive power generation and consumption by the energy management system, grid support, ancillary services, etc. Whenever a microgrid is in islanded mode, it will work as an autonomous system without a distribution grid power supply. In this mode of operation, fault in the transmission or distribution grid will not propagate into the microgrid. Whenever a microgrid operates in grid-connected mode, power flows bi-directionally between the distribution grid and microgrid at the point of interconnection. Hence, microgrids ensure the interrupted power supply to the end-user loads with high reliability. This book aims to bring together the design, installation, operation, and new research that has been carried out in the field of microgrid applications for commercial power systems.
