Many innovations are taking place in the charging, automotive and energy production fields, as well as in countless other areas. The use of electric vehicles is clearly under development. This is necessary for supply to keep pace with demand. Read more
Distribution system operators are investigating methods to facilitate a high penetration of distributed energy resources while maintaining network reliability in a cost effective way. Some of the challenges associated with a high penetration of distributed energy resources are network overloading, voltage violations, and inadequate fault protection. Mitigation measures to these challenges are investigated in a newly developed living-lab in the district of Strijp-S, Eindhoven, the Netherlands.
Electrical energy production from renewable energy sources and electrification of consumer energy demand are developments in the ongoing energy transition. These developments urge the demand for flexibility in low voltage distribution networks, on the one hand caused by the intermittency of renewable energy sources, and on the other hand by the high power demand of battery electric vehicles and heat pumps. One of the foremost ways to create flexibility is by using energy storage systems. This paper proposes a method to first optimize the siting, power and capacity rating, technology, and operation of energy storage systems based on the technical and economic value.
In view of the burgeoning demand for energy storage stemming largely from the growing renewable energy sector, the prospects of high (>300 °C), intermediate (100-200 °C) and room temperature (25-60 °C) battery systems are encouraging. Metal sulfur batteries are an attractive choice since the sulfur cathode is abundant and offers an extremely high theoretical capacity of 1672 mA h g −1 upon complete discharge.
Smart Charging strategies for optimizing the power grid, sustainable energy and energy price
The project focuses on the design of a reliable, safe and high-efficient dynamic inductive power transfer charging pad for electric vehicles. The research goes into dynamic modeling method, multi-objective optimization and foreign objects analysis.

Trolley 2.0 focuses on making the trolleygrid more sustainable and utilising the braking energy of the trolleybuses, consequently improving the stability(in terms of voltage profile) of the trolleybus grid. Various options like adding storage, smart charging of vehicles through the trolleygrid, integrating solar etc will be explored to achieve the goal

Batteries capability and charging are two of the main limitations in the large-scale-private use of EVs. Wireless power transfer technology gives several advantages over the charging through cable, such as an easier implementation of dynamic charging, convenience in case of autonomously-driven cars and safety in wet weather conditions. My project consists in the optimization of the power electronics topologies, compensation networks and control in wireless charging of EVs, for both static and dynamic case.

Distribution grids are undergoing deep changes due to the increase of distributed generation and new loads, such as EVs. The project aims at designing algorithms and guidelines for the integration of Battery Energy Storage System in distribution grids to enhance grids’ flexibility and renewable generation hosting capacity.

As electric mobility is continuously increasing, the increase and availability of charging points isn’t progressing as smoothly. A promising new method for installing public charging stations is to combine them with already existing municipal grid connections. Also promising is to integrate a charging point into an object that’s already connected to a municipal grid connection. Both types of solutions are being tested in Dutch municipalities. Aside from the technical aspects, regulatory and organisational issues need to be considered.
Inductive charging of electric vehicles is a promising technology, but it still needs further development. This is one of the main conclusions of research of inductive charging, conducted by ENGIE, at the request of ElaadNL, EVConsult and the municipality of Rotterdam (in Dutch).
The accepted H2020 project with 13 partners aims at simultaneously and accurately measuring the efficiency of the inductive power transfer (IPT) and the actual transferred power to the vehicle and also provides the means to sound and reliably demonstrate compliance with existing safety standards for human exposure. For this purpose, the consortium will develop the metrology support necessary for this technology and for the development of high-efficiency couplers for inductive charging of electric vehicles (EVs).
The EV-PV project aims at combining the two technologies by creating an electric vehicle charging infrastructure using PV panels. The focus is to reduce the energy demand on the grid due to electric vehicles by locally producing the charging power in a ‘green’ manner through solar panels. The EV battery doubles up as an energy storage mechanism for the PV system.
New EVPV technology can be used on locations with sufficient space for PV panels and electric vehicles, like business areas. Electric vehicles’ batteries are used as an energy storage, creating a regional microgrid.
This project aims at creating a development platform for soft-real time control applications. This platform will give 3rd party application developers the opportunity to develop (real-time) energy management applications that can utilise the maximum grid capacity without risking an outage. The platform is intended to an open platform to stimulate 3rd party application development.
Inductive power transfer (IPT) is the process of transferring power between circuits without wired interconnects by the process of electromagnetic induction in the near-field.
Goal is to electromagnetically model of such distributed systems and also provide design equations and analytical models to optimize both power and efficiency. The next focus of the work is the development of a charge coupler system that can perform the process of transferring power. Here, a lab scale prototype is intended as a research goal. High efficiency, wide-band gap semiconductors are considered for higher efficiency.
The ENBARK+ proposal develops a combination of zonal and nodal pricing methods combined with energy- and power-based modeling techniques for metropolitan distribution systems that have to handle an increasing amount of renewables and the embedding of electrical vehicles.
