Leveraging multi-type power sources for frequency support while disregarding dispatch non-anticipativity could challenge the physical feasibility of steady- state optimization with frequency dynamics. To this end

this paper elucidates the mechanism between the time-series uncertainty-mining characteristics of multi-type generation outputs during unit commitment in low-inertia systems with concentrating solar power and systems' sequential dispatch process in primary frequency reserve (PFR) and secondary frequency reserve (SFR). A multi-stage adaptive robust mixed-integer unit commitment (UC) model based on mixed decision rules (MDR) is further proposed. Additionally

targeting a challenging computationally demand posed by high- dimensional variables and discontinuity of the uncertainty set

an effective solution is proposed that integrates a lifted convex hull equivalent modeling with linear duality arguments and cutting plane method. Finally

the DN-based look-ahead rolling economic dispatch (ED) model is proposed. Simulations results demonstrate that the proposed multi-stage robust FCUC model is effective in leveraging frequency regulation characteristics of CSP plants and ensuring the frequency security.
