Two‐stage stochastic energy and reserve market clearing model considering real‐time offering strategy of renewable energy by Zhengting Jiang, Yunpeng Xiao, Taishan Xu, Qi Liu, Jianxue Wang

“…To fill the gaps, this paper incorporates the strategic offering models of renewable energy into the two‐stage stochastic energy and reserve market clearing model. Within the two‐stage framework, the first day‐ahead stage serves for energy and reserve market clearing, while the second real‐time stage considers the adjustments on offering quantities of renewable energy according to the fluctuations of renewable generations. …”

Educational Institutions of the System of State Labor Reserves of the USSR in 1941—1954: Adaptation to Migration Impact (Materials from the Sverdlovsk Region) by L. V. Zakharovsky, S. L. Razinkov

“…It is shown that the awareness of the impossibility of widespread use of compulsory punitive mechanisms without restriction was formed directly during the implementation of state policy in the 1940s — mid 1950s, it was also represented among the leaders of the system for training young skilled workers — the State Labor Reserves. It is noted that such an understanding leads already at the beginning of the 1940s, in the most difficult conditions of the initial period of the Great Patriotic War, to the development among the leadership of educational institutions and the regional administration of the State Labor Reserves mechanisms for adapting educational institutions and students to a complex of problems caused by the powerful migration impact. …”
