We report on a new measurement of the neutron $\ensuremath{\beta}$-asymmetry parameter $A$ with instrument Perkeo II. The main enhancements are high polarization $P=99.7(1)%$ from novel arrangement supermirror polarizers and reduced background improvements in beam line shielding. leading corrections were thus by factor 4, pushing them below level statistical error resulting significant reduction systematic uncertainty compared to our previous experiments. derive...
In future electricity systems, not only generation but also frequency stabilization must be provided by low-carbon technologies. Battery systems are a promising solution to fill this gap. However, uncertainties regarding their revenue potential may hinder investments. Therefore, we apply the agent-based market model AMIRIS simulate day-ahead and an automatic restoration reserves market. Demonstrating setup, chose scenario with high shares of renewable energies. First, back-test our historic...
The ongoing deployment of renewable energy sources (RES) calls for an enhanced integration RES into markets, accompanied by a new set regulations. In Germany, instance, the feed-in tariff legislation renewables has been successively replaced first optional and then obligatory marketing on competitive wholesale markets. This paper introduces agent-based model that allows studying impact changing policy instruments economic performance operators marketers. structure, its components, linkages...
A new measurement of the neutrino asymmetry parameter B in neutron decay, angular correlation between spin and antineutrino momentum, is presented. The result, B=0.9802(50), confirms earlier measurements but features considerably smaller corrections. It agrees with standard model expectation permits updated tests on "new physics" decay.
Increasing the market and system integration of renewable energy sources (RES) is regarded as key to reducing costs RES support transforming electricity system. In several EU countries, feed-in premium schemes have been implemented better align production with prices enhance efficiency marketing by increasing direct participation producers in markets. This paper examines lessons learned from German scheme, which was introduced Renewable Energy Sources Act 2012 an optional alternative...
In this paper we introduce FAME-Core, a Java library supporting development and execution of agent-based simulation models (ABM).It is main component the open Framework for distributed Agent-based Models Energy systems.FAME-Core offers rapid fast capabilities while reducing required programming skills efforts creating running complex ABM.
The proton asymmetry parameter $C$ in neutron decay describes the angular correlation between spin and momentum. In this Letter, first measurement of quantity is presented. result $C=\ensuremath{-}0.2377(26)$ agrees with standard model expectation. coefficient provides an additional for new improved tests.
In decentralized energy systems, electricity generated and flexibility offered by households can be organized in the form of community systems. Business models, which enable this aggregation at level, will impact on involved actors market. For case Germany, paper different scenarios are analyzed from perspective The main components these Community Energy Storage (CES) technology, tariff structure, goal. evaluation, a bottom-up system model is presented, retailer key actors. our model, we...
A reliable and cost-effective electricity system transition requires both the identification of optimal target states definition political regulatory frameworks that enable these to be achieved. Fundamental optimization models are frequently used for determination cost-optimal configurations. They represent a normative approach typically assume markets with perfect competition. However, it is well known real systems do not behave in such an way, as decision-makers have information at their...
Distributed generation is one of the pillars energy transition in Germany, Europe, and around world. Recent studies have underpinned several technical, social, economic benefits using Community Energy Storage systems (CES) for aggregation rising number so-called prosumers. Looking at German electricity market an agent-based approach, we investigate how deployment CES impacts prices integration renewable energies market. The agent-based-model AMIRIS used to simulate profit autarky maximizing...
This article analyses actors in the storage niche during German electricity transition. Thus, we develop a more differentiated understanding of and their activities. For that, employ analytical multi-level-perspective (MLP) framework to focus on interactions between old new technologies. Using data from expert interviews, investigate whether pathway resembles any four ideal types transition pathways for regime. Through our identify five actor market: Big 4 (EnBW, RWE, E.ON, Vattenfall),...
The LHCb (Large Hadron Collider beauty) experiment is designed to perform high precision measurements of B-meson decays. construction and installation the detector was finished early summer 2008, followed by intensive testing commissioning system in order be ready for first data taking. Despite forward geometry over 1 million cosmic events were collected addition beam dumps during LHC synchronisation tests provided very useful data. These allowed calibration spatial alignments several...
This article describes measurements of angular-correlation coefficients in the decay free neutrons with superconducting spectrometer PERKEO II. A method for measuring β-asymmetry coefficient is presented, as well a new determining neutrino-asymmetry B, which allows value proton-asymmetry C to be obtained first time. An ongoing experiment trying improve accuracy these quantities.
