A comprehensive review of wind power integration and energy storage

Wind energy integration into power systems presents inherent unpredictability because of the intermittent nature of wind energy. The penetration rate determines how wind energy integration affects system reliability and stability [4].According to a reliability aspect, at a fairly low penetration rate, net-load variations are equivalent to current load variations [5], and
