Study on Flywheel Capacity of the Power Compensator for Wind Turbine Generator

Abstract

Nowadays, the Wind Turbine Generator (WTG) system is remarkably increasing as one of the renewable energy resources in Japan. But in the WTG, the power fluctuations caused by the wind speed fluctuation are the most crucial issue in providing their energy to the utility. It was found that the power compensation system (PCS) with the suitable capacity is still unknown. In this paper, the argument to time range and standardized wind speed including fluctuations is discussed. We estimated the storage capacity of PCS at a wind profiles by standardization of wind speed and verified the validity of their capacities using a computer simulation. It was determined the suitable capacity of the power compensation system with this argument.
