To address wind curtailment and delayed frequency regulation in renewable-rich grids caused by CHP's limited peaking capability

a dynamic multi-objective optimization strategy integrating molten-salt thermal storage is proposed. The core innovation combines chaotic PSO and WOA with dynamic phase-shifting

layered thermal modeling

and grid-adaptive weights to resolve storage hysteresis

convergence traps

and multi-objective conflicts. Simulations demonstrate: under the CPSO-WOA

compared with the other existed strategies

wind curtailment drops from 15.4% to 7.3%

frequency response accelerates to 2.7 s

storage utilization reaches 75%

and operational costs decrease by 17.7%

with proven robustness under extreme conditions.
