Integrated generation- transmission expansion planning: a review of the state of the art
, 2016 In the last decade a great number of research works have approached the power systems planning problem by coordinating in a single optimization problem the generation expansion planning (GEP) and the transmission expansion planning (TEP).

Uncertainty in operational planning of power system generation
International Journal of Electrical Power & Energy Systems, 1980 Abstract Short-term scheduling of a power generation system is discussed with regard to the probabilistic character of the load demand and the effects of generation capacity outages. The probabilistic method and a practical algorithm of optimal unit commitment and load distribution among power stations is presented.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
