Hydrogen is becoming an increasingly important energy carrier in sector integration for fuel cell transportation, heat and electricity. Underground salt caverns are one of the most promising ways to store hydrogen obtained from water electrolysis using power generation renewable sources (RES). At same time, production can be used avoid curtailments during times low electricity demand or prices. The stored also high generation, e.g., with cells, cover fluctuations shortages caused by RES...
This article provides an overview of the requirements for a grid-oriented integration hydrogen energy storage (HES) and components into power grid. Considering general definition HES possible components, this paper presents future demand, electrolysis performance, capacity. These parameters were determined through various overall system studies aiming climate neutrality by year 2045. In Germany, targeted expansion renewable generation capacity necessitates grid to transport electricity from...
Demand data is as necessary for energy system analysis generation and grid information. When it comes to time series analysis, load profiles are required. In Germany standard (SLPs) widely used by network operators electricity modelers. Multiple research also business offers show that advanced techniques can improve forecasted small consumers loads. Hence, our contribution reviews SLPs suggested improvements along with other available data. a case study rural region in north-west Germany,...
The progressing integration of renewables (RE) into distribution grids leads to bidirectional power flows. Due the fact that infeed by RE exceeds grid capacities, bottlenecks occur increasingly and thereby renewable generation has be curtailed. For decision if countermeasures like flexibility options could applied, knowledge amount curtailed as well its local temporal availability is crucial. This study proposes an approach determine characteristics, which creates time series simulating...
Large shares of renewable energy production in the electricity grid make expansion and new technologies necessary. The unavailability models to address upcoming research questions led development open source models. Our work contributes establish open_eGo model for simulations by validating its assumptions results a rural region with high share wind energy. In particular, on electrical parameters graph structure are compared owner's along validation AC load flow at boundaries. It was found...
This paper describes the application of open source models and publicly available data sets for research in field power grid operation. The experience on implementation, modelling methodology obtained results is presented based three exemplary projects: HyReK, enera HyCavMobil. project HyReK focused network connection a hybrid plant OpenModelica software exporting physical equation set to computer algebra system analytic evaluation voltage dependency. In projects HyCavMobil, high-resolution...
Current methods of making crop cover estimates are time-consuming and tend to be highly variable. A low-cost, digital, red/near-infrared band ratioing camera (Dycam Inc., Chatsworth, Calif.) accompanying software (S. Heinold, Woodland Hills, were evaluated for estimating cover. The was tested using a set images having leaf areas known sizes with different crop, soil, lighting conditions. In the field, camera-based compared light bar measured estimates. Results indicate that image analysis...
