In a groundbreaking advancement for the wind energy sector, researchers have unveiled an innovative approach to optimizing collector circuits in onshore wind farms. This development, driven by the pressing need to achieve grid parity amidst China’s ambitious dual carbon goals, promises to significantly cut costs and enhance efficiency in wind energy production.
The study, led by Yi Hai from China Three Gorges Renewables (Group) Co., Ltd., introduces an improved fuzzy C-means (FCM) clustering algorithm that redefines how collector lines are designed and organized. As the wind power industry continues to expand rapidly, the financial burden of collector lines—often a substantial portion of overall investment—has become a critical concern. “Our improved algorithm not only considers the azimuth angle but also the spacing between units, ensuring a more efficient and cost-effective layout,” Yi stated.
By applying this advanced algorithm, the research team was able to effectively group adjacent units into the same circuit while preventing line crossings, a common challenge in circuit design. The algorithm incorporates a correction factor that adjusts the distance from machine positions to cluster centers, allowing for optimized circuit capacity. This meticulous approach culminated in the application of the dynamic Prim algorithm to refine line selection further.
The results are promising. The research demonstrated a reduction in costs of 2.6% for single-circuit and 5.4% for double-circuit collection lines. These figures not only highlight the potential for cost savings but also suggest a pathway toward more sustainable wind energy operations. “The findings indicate that our method can be a game-changer in the design of wind farm collector lines, providing a template for future projects,” Yi emphasized.
As the global energy landscape shifts towards renewable sources, the implications of this research extend beyond mere cost reductions. Enhanced efficiency in wind farm operations could lead to lower energy prices for consumers and a more competitive market for renewable energy providers. The optimization of collector circuits is a step toward realizing the full potential of wind power as a viable alternative to fossil fuels, contributing to a greener and more sustainable future.
Published in ‘发电技术’ (Power Generation Technology), this study not only sets a new benchmark for the design of wind farm infrastructure but also serves as a vital reference for industry stakeholders aiming to align with the evolving energy paradigm.
