Untersuchung verschiedener Handelsstrategien für Wind- und Solarenergie unter Berücksichtigung der EEG 2012 Novellierung

The new EEG 2012 law opens up for more parties to participate in the trading of wind and solar power, because of the bonus system that now compensates everybody for all market relevant costs, not only the Transmission System Operators. Therefore it can be expected, that the trading of renewable energies by private parties will increase. One of the central questions to be answered is how efficient does a balance responsible party have to be to stay competitive also with a small pool. The quantification of balance costs for different trading strategies is however complex and non-trivial. We propose a methodology in this study that accounts for this fact. Additionally, we analyse and show the requirements and the monetary value of Intra-Day trading for the handling of wind and solar power. The trading strategies proposed in this article make use of an uncertainty band around the forecasts used in the Intra-Day, in order to avoid double trading and thereby reducing the total balancing volume and the associated costs.

球墨铸铁组织与性能关系的探讨

通过对工作中积累的QT450—10金相组织与力学性能、化学成分诸多数据进行比较,探求组织和性能以及化学成分的内在关系。尝试说明在不满足制取抗拉试棒,只能利用本体取样做金相和化学成分分析的情况下,如何判定零件是否合格。试验结果表明,球化分级小于等于3级,石墨大小6级,珠光体数量小于等于珠30时QT450—10的抗拉强度和伸长率都能满足国家标准要求。在一定程度上可以用本体取样的试验结果代表该批铸件的质量。     

Commercialization as exogenous shocks: The effect of the soybean trade and migration in Manchurian villages, 1895–1934

The effects of commercialization and migration in traditional agrarian economies such as China's during the nineteenth and twentieth centuries have been a subject of ferocious debate. Using data from Manchuria on soybean cultivation and exports, we employ difference-in-differences and instrumental variable approaches to demonstrate a significantly positive relationship between growing soybeans for export and the returns to migration. Those who migrated to Manchuria in response to high market prices, and to villages more suitable for cultivating soy prospered most; they owned approximately two-thirds more of the arable land and one-third more of houses than those who failed to do so. Evidence suggests that the positive welfare effect of commercialization-cum-migration was confined not only to the rich, who seek to relieve the “land constraint” at home, but possibly also to the poor.     

Structural changes in exports of an emerging economy: Case of Turkey

This paper indicates that Turkish exports are subject to structural changes as Turkey integrates into global production networks. Integration, which leads vertical specialization in production and changes in the commodity composition of Turkish exports in favor of non-traditional commodities, paces up during economic reform periods. As the export shares of non-traditional commodities, which have higher import and income sensitivity but lower real exchange rate elasticity, increases, coefficients of the aggregate export function change accordingly. Nevertheless, high import and income elasticity of exports imply that the global growth pattern plays a significant role in determining exports of Turkey.
