This thesis explores variable renewable energy (VRE) integration, through multiple scales of energy modelling and analysis from the integrated assessment model MESSAGE, to the country-scale electricity system model LEAP, and the production cost model introduced in this work entitled SILVER. The MESSAGE...

aIt is no longer credible to say that solar can’t play a major role in a sustainable energy mix. Deutsche Bahn intends to run the entire German railway system on wind, solar and hydropower. The German economics ministry has collaborated with German companies to run a scaled model of the ...
Based on 19 models from the Coupled Model Intercomparison Project Phase 6 and the Multi-Source Weather (MSWX) dataset, bias correction and UNet downscaling approaches are used to develop high resolution dataset over the East Asian region, referred to as Climate Change for East Asia with Bias ...
The paleoclimate simulations consist of a 22,000 year transient simulation from the Community Climate System Model (CCSM3)41,46and a 21,000 year transient simulation using ECBilt-CLIO47. Decadal means of paleoclimatic simulations were obtained from CCSM3 (Feng He, pers. comm.) and EC-BILT (...
position-regulation capability. To further enhance the controller's robustness against exogenous disturbances, the baseline LQR is instead retrofitted with the proposed self-adjusting model-reference-adaptive-system that employs Lyapunov function to formulate a stable online state-compensator gain-adjustment ...
More importantly, in addition to producingscale-1 replicas(wherenr=no), in the second scenario we want to use the generative model forextrapolation, i.e., we would like to parametrize it to produce ascaled replicaRxthat hasnr=x·nonodes, wherexis called thescaling factor. The structural pr...
Here we use a tropical cyclone downscaling model driven by three global climate analyses that are based mostly on sea surface temperature and surface pressure data. The results support earlier statistically-based inferences that storms were undercounted in the 19th century, but in contrast to earlier...
It is worth to mention, that since the used model does not take into account the droplet volume expansion upon water solidification, the increase in the final droplet height is disregarded. As a consequence, it is anticipated that the simulated freezing time could be lower than the experiment ...
Performance Examples In the following examples the starting material was atomized to a stream of aerosol using a single jet atomizer (Model 9302A) from TSI Incorporated (St. Paul, Minnesota) with a nitrogen gas input pressure of either 25 or 40 Psi (corresponding to an output of 6.6 or 9.2...
