Abstract

This paper considers the complex frequency characteristics of large-scale wind power participation in frequency regulation and proposes a robust optimal dispatch method for high-penetration wind power systems considering secondary frequency drops. First

the frequency response characteristics of wind power

thermal power

energy storage

and loads are comprehensively considered to derive the mathematical expressions of the primary and secondary frequency drop processes in power systems

and extract key frequency indices. Second

taking into account wind power uncertainty and dynamic frequency constraints

as well as system operating costs and wind curtailment costs

a nonlinear chance-constrained optimal dispatch model for power systems is established. Subsequently

to address the nonlinear characteristics of the primary and secondary frequency drop constraints in the dispatch model

a two-stage iterative optimization method is proposed. Finally

case studies are conducted on the IEEE 39-bus system and an actual power system in China. The results demonstrate that the proposed method effectively balances system economic operation and frequency stability while significantly improving renewable energy utilization.
