Study on Calculation of Dynamic Penetration Limit of WTG and Applications of BESS in Power Systems

풍력발전기와 같은 신재생에너지원은 기존 한 상황에서는 주파수 변동에 신속히 대응하지 못하므로 주파응답성능을 Since the characteristics of Renewable Energy Sources like wind turbine generators are very different from those of existing thermal power generators and their response to the sudden change of the frequency are not as good as that from thermal power generators. Especially when the penetration level of the wind power generation is substantially high, the output from the WTG would be possibly limited to keep the stability of power systems. For this, this paper implements the process for calculating the dynamic penetration limit of WTG and analyze the potential application of BESS for increasing the dynamic penetration limit of WTG.
