Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
In this paper a comprehensive model of electrical power grid with outage planning and forced outage simulation for prospective studies of transmission system operators is presented. The model is formulated as a mixed-integer linear programming (MILP) optimization problem with overall costs minimization being the objective. The power flow through the transmission system is estimated by DC load flow method. Thermal plants are modelled as multi-block, multi-fuel units with spinning reserves holding capability. Pumped-storage as well as conventional hydroelectric power plants are modelled. Outage planning problem is formulated as a MILP considering network load profile and marginal prices of power plants. A forced outage algorithm with partial unit commitment fixation is used for the grid behaviour simulation during and after unexpected plant failures. The computational results of an annual simulation of Czech 400 kV high voltage network (with 61 power plants, 110 blocks and 31 nodes connected by 53 lines) are presented. A state-of-the-art commercial general-purpose solver Gurobi is used to solve MILP models. Copyright © 2013, AIDIC Servizi S.r.l.
