Estimation Method of Harmonic State Based on Improved Generative Adversarial Network
The traditional harmonic state estimation based on the least-square method is limited by few measuring devices
difficulty in obtaining accurate harmonic impedance
complex network topology and variation of grid operation mode
which results in the problems such as underdetermined measurement equations
non-global observation of the power system and difficulty in accurately extracting coupling relationships between buses. This paper proposes a harmonic state estimation method based on the improved generative adversarial network. The method is based on the pix2pix harmonic state estimation network to fit the coupling relationship between the monitored buses and the target buses. And the collected historical harmonic data is used to batch train the model. The harmonic current and harmonic voltage amplitude of the target buses are estimated by the generated network after training to achieve data-driven harmonic state estimation. The model is tested in an environment with noise
and the simulation results verify the effectiveness of the proposed method.
