Proposal of evaluation method of electric power fluctuation using wavelet transform

The output power of electric generating system using natural energy contains electric power fluctuation. The study that smooths the electric power fluctuation is actively studied. And, the m to evaluate a characteristic of the electric power fluctuation quantitatively uses various methods. But they don´t represent the feature of electric power fluctuation enough. This paper proposes an evaluation method of electric power fluctuation using wavelet transform and considered it. Non-periodic fluctuation characteristic of the electric power fluctuation can be expressed by using this evaluation method.
