Primary-Frequency-Regulation Coordination Control of Wind Power Inertia and Energy Storage Based on Compound Fuzzy Logic

Abstract

The increasing proportion of wind power systems in the power system poses a challenge to frequency stability. This paper presents a novel fuzzy frequency controller. First, this paper models and analyzes the components of the wind storage system and the power grid and clarifies the role of each component in the frequency regulation process. Secondly, a combined fuzzy controller is designed in this paper, which realizes the cooperative control of frequency regulation considering wind power running state, battery energy management, and power grid stability. Finally, this paper establishes typical operation scenarios of various time scales to verify the effectiveness and feasibility of the proposed control strategy.
