Assessing the impact of power rate limitation based wind control strategy

With the DOE 20% by 2030 scenario for wind capacity, wind penetration is on the rise, and intermittency of this energy resource must be addressed since it hurts grid reliability and increases ancillary service needs. To cope with the rising variability, this study analyzed the effects of wind control, specifically absolute power rate limitation (ramping control). A ramping constraint was modeled to cap the increase in energy output of a wind generation unit for a minute interval, simulated using the IEEE 24 bus system. Results of this study include a decrease in variability of the wind output, a decrease in the ancillary service regulation requirement, a decrease in the production cost of the system, a decrease in de-commitments of coal-fired power plants, and a decrease in cycling cost of the system.
