Energy limits in primary frequency control with short-term frequency-band allocation
IEEE PES Innovative Smart Grid Technologies, Europe, 2014 Frequency stability of large power systems requires the use of very fast flexible resources to contain frequency excursions. Potential candidates able to provide such flexibility are demand response and storage. However, capacity and energy constraints usually restrict their use to exceptional and rare events.

Theoretical Integrated Electric Quantity of Primary Frequency Control
Journal of Physics: Conference Series, 2022 Abstract At present, the qualification rate of primary frequency control of hydropower units in the southwest power grid is low. The current grid has defects in the calculation method of the theoretical integral power of primary frequency control of hydropower units.

Optimization of constant power control of wind turbines to provide power reserves [PDF]
, 2013 In several countries, the wind power penetration increased tremendously in the last years. As the current wind turbines do not participate in frequency control nor reserve provision, this may compromise the proper functioning of the primary control and ...
