To handle significant variability in loads, renewable energy generation, as well as various contingencies, (two-stage) robust optimization method has been adopted to construct unit commitment models and to ensure reliable solutions. In this paper, we further explore and extend the modeling capacity of two-stage robust optimization and present two new robust unit commitment variants: the expanded robust...
To reveal the change law of the simulation error of grey model GM(1,1) with translation transformation applying on the original sequence, in this paper, the experiments based on 55 real world data sequences have been conducted to study how the translation transformation influences the grey models' error characteristics. The results show that a larger translation transformation can make the total error...
In wireless sensor networks, the resource-limited sensor nodes collect and transmit sensing readings to Sink node collaboratively in multi-hop manner to conserve energy. For more energy-efficient data collection, we consider the problem of spatial clustering, which aims to group the strong correlated sensor nodes into the same cluster for rotatively reporting representative data later, and propose...
