Impact of wind power integration on operating reserves

Wind power integration leads to new challenges for power system operator arising from the variability and the forecasting uncertainty. Many studies have treated technical and economic impacts occurred at high level of wind penetration. Operating reserves determination taking account the variability and the uncertainty of wind generation is considered as a crucial impact to the power system operator. In this paper, different rules are used to calculate the operating reserves in the Tunisian power system and the impact of wind power penetration is studied.
