TransnetBW Challenge:

Energy System 2050

In theEnergy System 2050, the demand for flexibility will increase strongly because generation will be largely from renewables and thus volatile and not controllable. This requires a controllable electricity demand that can follow the supply.

Goal

The main goal of the challenge is the identification and evaluation of possible business cases for the provision of vehicle-to-grid (V2G) services by private e-cars owners, i.e. under which conditions (economic, technical constraints) private citizens are assumed to be willing to offer this flexibility service to the grid, and which incentives should be put in place in order to mobilize such flexibility potential.

In addition, an assessment of a trade-off between the cost of participation to V2G on the one side and need for alternative flexibility options (e.g. stationary batteries, grid reinforcement) on the other side should be analyzed.

Fraunhofer-Institut Challenge:

Optimize daylight harvesting systems

Since irregularities occur due to various work in the barn, we want to install an animal welfare-friendly daylight harvesting monitoring system in a chicken barn through Computer Vision. Daylight harvesting systems use daylight to offset the amount of electric lighting needed to properly light a space, in order to reduce energy consumption. This is accomplished using lighting control systems that can dim or switch electric lighting in response to changing daylight availability.

Goal

On the basis of computer vision, the potential for optimal use of daylight is to be determined.

For this purpose, the participants will receive data from the Fraunhofer Institute at the virtual kickoff.

Background

Due to the natural rather dim environment, the eye of the poultry has adapted. Daylight that is pleasant for humans is often too bright and discomforting for poultry. On the other hand, the birds can see less well at night, so a barn that is too dark leads to poor orientation and thus less feed and water intake. Therefore, it is important to have a lighting programme that optimally fulfils animal welfare needs. The lighting programme can influence movement activity, feeding behaviour and feather pecking. Sufficient lighting and light promote health and encourage the broilers to grow healthily. Ideally, the barn has sufficiently large windows because it is not always possible to give the animals free access. Then it is good if sufficient daylight enters the barn.
