Primary frequency control in future GB power system with high penetration of wind generation

摘要

The system inertia reduction, driven by the integration of renewables, imposes significant challenges on the primary frequency control to maintain the post-fault frequency evolution within the security boundary. Dynamic simulations through a simplified GB power system dynamic model are carried out in this paper to illustrate the impact of declining system inertia on the primary frequency control. This paper also demonstrates the increased requirement on primary frequency response driven by larger online plants and higher penetration of wind generation. Furthermore, an advanced stochastic system scheduling tool is applied to quantify the amount of primary frequency response provision as well as the associated cost and carbon emission under two representative GB 2030 system scenarios.
