Abstract

This paper proposes a variable universe fuzzy adaptive control method that considers both the output characteristics of distributed PV and time-domain frequency features, enabling active provision of system frequency deviation suppression and inertial support. The proposed method incorporates multidimensional fuzzy rules encompassing illumination variation, system frequency deviation, and its rate of change. By adaptively adjusting power output, it enhances system frequency response characteristics. Simulation results demonstrate that this approach effectively improves both transient and steady-state frequency performance in power systems with ultra-high PV penetration, thereby strengthening grid security and stability.
