Abstract
With the widespread application of modern power electronic devices, harmonic pollution and reactive power issues in power systems have become increasingly severe, affecting power quality and system stability. To address these challenges, this study focuses on the coordinated control strategy for harmonic mitigation and reactive power compensation. By establishing a unified mathematical model that integrates harmonic suppression and reactive power compensation, a novel comprehensive control system based on an adaptive filtering algorithm is proposed. This system employs multi-ob jective optimization methods to achieve effective harmonic current suppression and precise reactive power compensation while ensuring grid voltage stability. Experimental results demonstrate that the proposed scheme maintains excellent dynamic response characteristics under various operating conditions, reducing harmonic distortion to less than 3% and increasing the power factor to over 0.98. Compared with traditional single-treatment approaches, the coordinated control strategy presented in this study not only enhances overall system performance but also reduces equipment investment costs, offering significant technical and economic advantages. Additionally, the research innovatively incorporates an intelligent prediction mechanism that adjusts control parameters in advance according to load variation trends, further enhancing system robustness and adaptability, thus providing new insights and technical support for the efficient and stable operation of power systems.
