Frequency Regulation and Economic Optimization of Thermal-Energy Storage Coordination Under Time-Varying Inertia Conditions
摘要
Abstract
To address the challenges posed by time-varying system inertia and the insufficient adaptability of conventional thermal-storage frequency regulation strategies under high renewable penetration,this paper proposes a coordinated thermal-storage frequency control strategy based on online inertia estimation and adaptive deadband optimization.The strategy employs a hierarchical coordination mechanism:under small disturbances,energy storage systems—acting as fast,distributed flexible resources—are prioritized for response through a reduced deadband setting,thereby avoiding frequent cycling and wear of thermal units;under large disturbances,the equivalent system inertia is identified via inversion of the frequency response,enabling adaptive adjustment of the storage's virtual inertia and droop coefficient to dynamically compensate system damping.Furthermore,a full-lifecycle cost model incorporating cycle-life degradation is established to quantify the economic benefits of the proposed strategy.Simulation results demonstrate that the approach effectively mitigates system oscillations while significantly reducing overall frequency regulation costs,offering a technically and economically viable solution for distributed energy storage participation in grid ancillary services and frequency stability management in low-inertia power systems.关键词
