Development of a Load Profile Generator for Non-road Mobile Machinery

This research presents a Load Profile Generator model for non-road mobile machinery, which depicts the most common operational profiles that reflect real-world conditions. This technological bottom-up model enables users to parameterize specific machines for simulation and observe their power demand at the actuator interfaces. The application of the Load Profile Generator covers different non-road mobile machinery categories, such as construction, agriculture, industrial and forestry. In this study, the Load Profile Generator was used to demonstrate common operations of material handler and forest forwarder, which have been validated against real-world data to match the results. The usage of Load Profile Generator aids engineers in evaluation machines performance by developing operation strategies. It opens doors to further systems analysis as it can serve as an interface for energy demand calculations. The model's results are accurate enough to provide a sufficient understanding of a wide range of non-road mobile machinery load profiles as well as insights about alternative fuel and power supply concepts helping in optimising the system simulation.

High-Resolution Rooftop-PV Potential Assessment for a Resilient Energy System in Ukraine

Rooftop photovoltaic (RTPV) systems are essential for building a decarbonized and, due to its decentralized structure, more resilient energy system, and are particularly important for Ukraine, where recent conflicts have damaged more than half of its electricity and heat supply capacity. Favorable solar irradiation conditions make Ukraine a strong candidate for large-scale PV deployment, but effective policy requires detailed data on spatial and temporal generation potential. This study fills the data gap by using open-source satellite building footprint data corrected with high-resolution data from eastern Germany. This approach allowed accurate estimates of rooftop area and PV capacity and generation across Ukraine, with simulations revealing a capacity potential of 238.8 GW and a generation potential of 290 TWh/a excluding north-facing. The majority of this potential is located in oblasts (provinces) across the country with large cities such as Donetsk, Dnipro or Kyiv and surroundings. These results, validated against previous studies and available as open data, confirm Ukraine's significant potential for RTPV, supporting both energy resilience and climate goals.
