Curtailed wind energy is a challenge in utilities with high wind energy penetration. This happens mainly when wind generation exceeds load minus the minimum stable operating point of generation units. At first, the role of generation mix on the curtailed wind energy is analyzed. Then, demand response (DR) applications are modeled to quantify additional reductions in the curtailed wind energy. The...
Integrating additional wind energy into the existing power system may cause wind curtailment due to the system operational constraints and reliability requirements. Effective ways to mitigate this problem are to use energy storage or increase transmission capacity. In this paper, the impacts of coordinating with pumped storage and increasing transmission capacity on wind output curtailment mitigation...
Due to its intermittent nature, high wind penetration requires more flexibility in the electric power grid to provide the balance. Large scale energy storage is one such option that allows the intermittency to be absorbed in real time. Two types of large scale energy storage technologies including Sodium Sulpher (NaS) battery and compressed air energy storage (CAES) are studied in this paper. In this...
