Testing for a stable grid
7 January 2019 by FHI IE
The transition to renewable energy poses a challenge to the vaunted reliability of the Dutch power grid. Renewable energy is highly variable, so a confluence of circumstances can lead to instability or even power failures.
Renewable energy sources, such as wind turbines and solar panels, are an increasing part of the Dutch energy supply. While this transition is desirable, it also presents challenges for grid stability. Renewable energy derived from sun and wind fluctuates strongly, increasing the risk of too much or too little voltage. To ensure a reliable energy grid, grid operators need to be able to reliably predict the rare scenarios in which the grid becomes unstable.
During his presentation, Raymond Vergouwe of Bender Benelux will introduce you to different grid systems and the benefits of various monitoring methodologies. Raymond elaborates on the floating IT grid system and shows a demo where an insulation fault is made in a floating grid system.
Battery systems are used to use less electricity or to be less dependent on the grid. Ramon Zambelli of Nextys will highlight some of the possibilities of using wireless battery systems. What is the technical operation of such a system? And what aspects should be considered if this is chosen? Of course, Zambelli will also show the advantages of wireless battery systems.
Testing batteries
7 January 2019 by FHI IE
Batteries and batteries must not only be of high quality, but also safe and reliable. Numerous aspects, such as misuse, benchmarking, durability, electrical safety and electromagnetic compatibility (EMC), affect the battery. This means that several thorough tests on quality standards are extremely important.
There is a growing demand for efficient energy storage, partly due to the huge increase in mobile devices. This means the use of all kinds of batteries.
During his presentation, Kees Winkel of Weiss Technik will show what testing methods are available for li-on batteries and explain the corresponding safety requirements. Andrea Vinci of Tektronix-Keithley shows an effective and flexible test programme for fully discharging a battery.
Better Battery Management
7 January 2019 by FHI IE
Thanks to properties such as high energy density, lithium-ion batteries are used in numerous applications. Think portable devices and electric vehicles. To ensure the safe, efficient and reliable operation of lithium-ion batteries, a Battery Management System (BMS) is vital.
The BMS is a piece of extra intelligence that ensures that the entire battery pack can be optimally charged, discharged and cooled. Some 'smart' battery packs can even cool harder on one side, for example the side of the car facing the sun, than the other.
The BMS is also a source of information on battery health. It indicates when a battery cell or battery module in the pack is no longer functioning properly. When that happens, the still-functioning batteries have to do more work, causing them to wear out faster. So it is important to get a signal in time when a battery or battery module fails, so you can replace it in time.
Often, for cost reasons, the BMS is done in a minimal version. Sander Kool of Engineering Spirit explains that it is precisely a more complete BMS that offers possibilities beyond the legal requirements. With smaller systems, such as e-mobility, this has concrete benefits. It becomes possible to assess warranty claims or increase the lifetime of the package.
