Duck curve phenomena occurs when solar energy in higher quantities is integrated into the power grid. This results in excess generation that cannot be delivered during peak hours and a part of the load that cannot be supplied during off-peak hours. This paper proposes a novel, 2-step methodology to determine the effects of duck curve and also to flatten the …
