Taking the advantages of fast convergence, high ability of global optimization in artificial fish-swarm optimization algorithm, this paper optimizes the background sequence, time sequence error and the combination of them in grey model GM (1, 1). Practical examples for GDP prediction are given and the simulation results indicate that the improved model gives better prediction precision and may have...
The superconductor-triggered type fault current limiter (STFCL), which was developed by KEPCO and LS Industrial Systems, is under operation for a verification test at KEPCO's power testing center. The STFCL is composed of a superconductor, a fast switch and a current limiting resistor. In this paper, we investigated the empirical modeling of the STFCL using principal component based and fuzzy support...
In this paper, we define two new unbiased GM (1, 1) models for the selection of initial conditions: starting-point fixed unbiased GM (1,1) (SUGM (1,1))and ending-point fixed unbiased GM (1, 1) (EUGM (1,1)), which are based on the unbiased GM (1, 1) regarding the 1-th and the n-th vector as the initial condition. Then it gave initial condition an amendment item respectively and carried out an optimization...
