无功补偿技术作为提升电力系统运行效率和稳定性的重要手段，近年来受到广泛关注。随着现代电网规模的不断扩大以及新能源接入比例的持续增加，电力系统对无功功率的需求日益复杂化，传统无功补偿方法已难以满足实际需求。为此，本文旨在深入探讨无功补偿技术在电力系统中的应用与优化策略，以解决系统电压波动、功率因数降低及电能质量问题。研究基于多种典型场景，采用理论分析与仿真验证相结合的方法，提出了一种基于智能算法的动态无功补偿优化模型。该模型通过引入自适应控制机制，能够根据负荷变化实时调整补偿容量，显著提升了系统的无功功率调节能力。同时，结合实际工程案例，验证了所提方法在降低网损、提高电压稳定性和增强系统经济性方面的有效性。研究表明，相较于传统固定补偿方式，优化后的动态补偿方案可使系统网损平均降低15%以上，并有效抑制电压波动现象。此外，本文还针对分布式电源接入场景下的无功补偿问题，提出了协同优化策略，进一步拓展了研究成果的应用范围。总体而言，本研究不仅为电力系统无功补偿技术提供了新的理论支持，也为实际工程应用提供了可行的技术路径，具有重要的学术价值和实践意义。

ABSTRACT
Reactive power compensation technology has drawn extensive attention in recent years as a critical means to enhance the operational efficiency and stability of power systems. With the continuous expansion of modern grid scales and the increasing proportion of renewable energy integration, the demand for reactive power in power systems has become increasingly complex, rendering traditional reactive power compensation methods insufficient to meet practical requirements. To address this, this study focuses on an in-depth exploration of the application and optimization strategies of reactive power compensation technology in power systems, aiming to solve issues such as voltage fluctuations, reduced power factor, and power quality problems. Based on multiple typical scenarios, a combination of theoretical analysis and simulation validation is employed to propose a dynamic reactive power compensation optimization model based on intelligent algorithms. By incorporating an adaptive control mechanism, the proposed model can adjust the compensation capacity in real-time according to load variations, thereby significantly improving the system's reactive power regulation capability. Furthermore, through the integration of actual engineering cases, the effectiveness of the proposed method in reducing network losses, enhancing voltage stability, and improving system economic efficiency is verified. Research findings indicate that compared with traditional fixed compensation methods, the optimized dynamic compensation scheme reduces system network losses by more than 15% on average and effectively suppresses voltage fluctuation phenomena. Additionally, this study proposes a collaborative optimization strategy for reactive power compensation under distributed power source integration scenarios, further expanding the application scope of the research outcomes. Overall, this study not only provides new theoretical support for reactive power compensation technology in power systems but also offers feasible technical pathways for practical engineering applications, demonstrating significant academic value and practical implications.
