A lab-based test setup was developed to simulate a novel droop rate controlled DC bus charging plaza installation in the Netherlands. The system consists of multiple bidirectional DC charging points, a PV array and a bidirectional grid connection. Currently the installed system employs linear droop control …

The need for increasing further the penetration of Renewable Energy Sources (RESs) is demanding a change in the way distribution grids are managed. In particular, the RESs intermittent and stochastic nature is finding in Battery Energy Storage (BES) systems its most immediate countermeasure. This work …

In Vlissingen, the municipality wants to make a selected neighbourhood natural gas-free. In order to support this, they have been granted a subsidy. There are many important stakeholders in this project such as the housing corporation l’Escaut which owns most of the houses in the neighbourhood. All of …

The flexible strain sensors have been a topic of interest for multiple studies in the past years. These sensors are soft, bendable mechanisms, which can be applied to substrates through printing or other means. They can indicate longitudinal strain through resistance change, which means that they can …

An operational amplifier based instrumentation amplifier (IA) with a common-mode rejection ratio (CMRR) independent of resistance tolerances is presented in this paper. The CMRR is determined by the operational amplifier characteristics. The IA shows a high CMRR up to 100 kHz. Moreover, since the presented …

Droop control is used for power management in DC grids. Based on the level of the DC grid voltage, the amount of power regulated to or from the appliance is regulated such, that power management is possible. The Universal 4 Leg is a laboratory setup for studying the functionality of a grid manager for …

The Netherlands is aiming for the roll-out of more solar PV. However like many densely populated countries, the country is running into issues of lack of space. Opportunities around infrastructural works like highways provide space without compromising the landscape. Examples of this double use are already …

This Vehicle-to-City (V2C) Operational Pilot, Flexpower, was deployed in two phases in Amsterdam from the beginning of March 2017 up to the end of May 2020 [1]. The first phase, defined as Flexpower 1, ran from March 2017 until end August 2018. The second phase, Flexpower 2, encompasses May 2019 – May …

Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 …
