To perform theoretical calculations of electronic structures of high Z atomic ions,one has to consider the configuration mixings due to excitations and rearrangements of the core and valence electron orbitals with the same principal quantum *** present a method to examine systematically such configuration mixings along isoelectronic *** an illustrative example,such configuration mixings give rise to a reversed fine-structure splitting of 4^(2)F5/2,7/2 states for atomic ions with Z≈36 along the potassium isoelectronic sequence;while the 5F,6F,and 7F have normal fine-structure splittings.

The paper proposes a stochastic unit commitment(UC)model to realize the low-carbon operation requirement and cope with wind power prediction errors for power systems with intensive wind power and carbon capture power plant(CCPP).A linear re-dispatch strategy is introduced to compensate the wind power deviation from the spot *** robust optimization technique is employed to obtain a reliable commitment plan against all realizations of wind power within the uncertainty set given by probabilistic *** proposed model is validated with IEEE 39-bus *** advantages of flexible CCPPs are compared to the normal coal-fueled plants and the impacts of robustness controlling are discussed.
