Research on power grid energy saving and loss reduction control methods under the harmonic influence

Abstract

To reduce energy consumption and power grid operation costs, a control method that considers the influence of harmonics is proposed for power grid energy saving and loss reduction. The zip load model is utilized to build the power grid load model, and voltage characteristic curves are obtained under different parameters to calculate network loss. Furthermore, the voltage RMS and total harmonic distortion of nodes are calculated under varying load levels. Ultimately, a control objective function is established to achieve power grid energy saving and loss reduction. Experimental results indicate that this method outperforms traditional methods in terms of voltage response effect and achieves a more extensive reduction range of network loss, with a maximum reduction exceeding 35%.
